Product Update: Kinetrol VLS Limit Switch Box

VLS Limit Switch Box
After a decade since the launch of the Kinetrol Universal Limit Switch Box it has become necessary to replace the tooling. As a result, Kinetrol has taken the opportunity to make some improvements to the design.

With the continued pressure for modularization and commonality a new precision die cast switch box will offer some positive improvements over the current model, including more internal space for future developments. The new design is known as the VLS Limit Switch Box.

Reduction in Weight. The unit will offer a reduction in weight of the standard 07 version from 2.32 lbs (1.05 kg) to 1.50 lbs (0.68 kg).

All New Plastic Coupling. Improved access to mounting screws for all electronic options for easy actuator mounting. Coupling is permanently retained in the box and does not need removing.

New coupling has a lower Oring which makes all shafts discretely sealed when not mounted. Coupling retainer is replaced with an integral shoulder on the coupling.

All new switch strikers. Common standard strikers for both mechanical switches and proximity sensor activation.

New Standard V3 Switch (004). New V3 switches offers a more defined switch point.

New Mounting for Model 03 and 05. The VLS Limit Switch Box will be supplied as a Model 07 Female Square as standard, (only one size box) which can then be converted with the use of two adaptor options to suit Model 03 and Models 05 Actuators reducing the number of switch box variations distributors stock. SP1620 - Model 03 mounting kit (includes removable plate coupling and fixings) SP1621 - Model 05 mounting kit (includes removable plate and coupling and fixings)

New Standard Conduit Entries. The conduit entries will remain M20 for ISO and 1/2” NPS for ANSI however the land profile has been changed. The additional entries on the four-entry version remain unchanged.

Switch Options. All switch options will be available including the pneumatic switch option (002) except for ATEX approved versions. ATEX Approved switch options (001, 002, 003 and 009) are currently undergoing ATEX testing and will be available later. As a result, these will continue to use the older design ULS.

Please refer to the Kinetrol coding on the VLS Tech Bulletin located on this Kinetrol USA web page.

Modular Concept. These changes will affect the modular approach when fitting the VLS box to Model 03 and 05 actuators. On actuator Models 07 to 15 there is no change. The discrete option for Models 16 to 30 will now utilize SP1602 07/05 reducer and SP1601 Discrete 05 Drive Adaptor offering a price saving over the old design.

VLS Coding. The coding has been changed to reflect the new design by adding a “V” after the U for non ATEX standard options. ATEX switch options (switch type 001, 002, 003, 009) will remain as “0” after the U in the code.
Examples of code change:

  • 097-104U005004M (DA+ULS) becomes 097-104UV05004M (DA+VLS)
  • 077-004U005004M (ULS) becomes 077-004UV05004M (VLS)
  • 077-001U001000 (ULS ATEX) is unchanged

Angle Retransmit and Pot Assembly – The new Angle Retransmit and Potentiometer uses a geared coupling which replaces the standard coupling when fitted. This new design will also offer an additional price savings. The old ULS Angle Retransmit assembly is not compatible to retrofit with the new VLS unit. All other options are unchanged including AS-interface, Terminal Blocks, Multi-Terminal PCB.

Electropneumatic Valve Positioner Offering Precise Control, Smooth Operation, and Fast Response

Kinetrol EL
Features of the Kinetrol EL positioner (click on image for larger view).

The Kinetrol EL is one of the valve automation industries best performing electro-pneumatic positioners available. It combines the precision and adaptability of a digital electronic control circuit with the smoothness and efficiency of Kinetrol's proven proportional servo valve, to give the best available 4-20mA positioning performance from rotary pneumatic actuators.

To compliment this unbeatable performance, the EL combines the easiest available setup procedure, easiest access to all functions and options, easy connectivity, and a compact all-metal housing, unique easy-set isolated angle retransmit, and limit switch options inside the same enclosure.

The EL positioner is designed to smoothly and precisely drive a rotary or linear actuator to a position set by the 4-20 mA input signal, and then accurately hold it there until the signal changes.

Inside the EL, a microprocessor in the loop powered 4-20 mA positioner circuit reads signal via one channel of a 12-bit A-D convertor, reads the position voltage from tie pot via the second channel of the A-D convertor, and compares the two. If an error between desired position and actual position exists, the EL changes it's output to the servo valve in order to drive the actuator in the direction required to eliminate the error.

In sync with the movement of the actuator, the feedback pot voltage changes, and the microprocessor continually calculates how to adjust the servo valve in order to guide the actuator accurately into position. Because the servo valve is a fully proportional device, it can be adjusted precisely and smoothly to slow the actuator to a stop exactly at the required position.  Programmed in the microprocessor is an advanced algorithm that allows this critical dynamic valve adjustment to be made correctly, giving optimal results with any actuator/load combination. Slow or fast responding, high friction or low friction, high inertia or low inertia, all can be optimized by PGAIN and DAMP parameters via the positioner circuit pushbuttons. The 12-bit A-D conversion gives the amazing resolution of approximately 1/40 of a degree angular.

Rugged Design Makes This Vane Actuator the Best Choice for Any Valve or Damper Automation Job

Watch the video below for a quick understanding of why Kinetrol Vane Actuators provide the longest service life in the toughest valve and damper applications.


Accuracy, Smooth Operation, and Efficiency Key to Industrial Valve Postioner

EL electro-pneumatic positioner
EL electro-pneumatic positioner
The EL electro-pneumatic positioner combines the precision and adaptability of a digital electronic control circuit with the smoothness and efficiency of Kinetrol's proven proportional servo valve, to give the best available 4-20mA positioning performance from rotary pneumatic actuators. This unbeatable performance is combined with the easiest available setup procedure, easiest access to all functions and options, easy connectibility, and a truly compact all-metal enclosure, plus unique easy-set isolated angle retransmit and limit switch options inside the same enclosure.

The EL positioner is designed to drive a rotary or linear actuator to a position set by the 4-20 mA input signal, and then hold it there until the signal changes.

The microprocessor in the loop powered 4-20 mA positioner circuit reads signal via one channel of a 12-bit A-D convertor, reads the position voltage from tie pot via the second channel of the A-D convertor, and compares the two. If it detects a position different from that required by the signal, it changes its output to the servo valve in order to drive the actuator in the direction required to reach the correct position. As the actuator moves, the feedback pot voltage changes, and the microprocessor continually calculates how to adjust the servo valve in order to guide the actuator accurately into position. Because the servo valve is a fully proportional device, it can be adjusted precisely and smoothly to slow the actuator to a stop exactly where it should be.  The microprocessor is programmed with a sophisticated but compact algorithm which allows this critical dynamic valve adjustment to be made correctly to give optimal results with any actuator/load combination - slow or fast, low friction or high friction, low inertia or high inertia, all can be optimized by PGAIN and DAMP parameters via the positioner circuit pushbuttons. The 12-bit A-D conversion gives resolution of about 1/40 degree.

EL positioner curve
EL positioner curve
The relationship between the input signal and desired position (the "characteristic") is stored in the microprocessor's memory. It can be set to follow any one of eleven pre-programmed curves between its two endpoints. The endpoints (each a combination of a signal value and a position) are set by the user via the pushbuttons. One of the eleven curves is a linearly proportional characteristic - this characteristic only can be selected to give movement of the actuator for signals extrapolated below the low endpoint and above the high endpoint, or to stop dead on signals below the low and above tie high endpoint. The "stop dead" behavior is the only option for the other ten non-linear curves.

The settings entered by the user are stored in non - volatile memory, and are retained even if power (i.e. signal) is lost.

Rotary Vane Valve Actuators

Rotary vane actuator
Rotary vane actuator
A rotary vane actuator is simply a part of an automated valve assembly: its role is to change the position of the valve, converting the motive force of fluid pressure into torque and applying it to a valve stem.

Quarter turn valves are widely used in industrial process automation. Their application is primarily for operations requiring fully open or fully closed valve trim positions, although some do provide modulating service. A rotation of the valve stem through a 90 degree arc will reposition quarter turn valve trim between open and closed positions. A rotary vane actuator is well suited for driving this type of valve, with its own 90 degree arc of movement.

A rotary vane actuator operates quarter turn valves, dampers and louvers. A pressure tight housing contains a movable vane which is sealed to the sides of the pressure chamber by means of a low friction gasket. Inlets into the chamber on opposing sides of the vane allow a controller to produce a pressure differential across the vane. The vane will move, in response to the pressure differential, in either direction. A shaft is connected to the vane and the vane acts like a lever to rotate the shaft as the vane is moved by fluid pressure. The torque produced by the actuator assembly is primarily dependent upon the applied fluid pressure.

Hydraulic rotary vane actuators have the ability to handle large amounts of fluid and dynamic motions, exhibiting also qualities of durability and compactness. Pneumatic vane actuators use plant air pressure as the motive force. Both types generally have few moving parts and require little regular maintenance. A variety of typical automation accessories and options are available to customize a unit for a particular application.

Kinetrol Spring Return Units: Spiral Torsion Springs Are Key

Spiral torsion spring
Simple view of spiral
torsion spring (protruding
tab and hex center

Spiral torsion springs are found in many places - clocks, watches, timers ... and Kinetrol spring return units!

Capable of storing much more energy than a typical compression spring, and working in smaller, more compact packages, spiral torsion springs for valve and damper actuation are a proven step-up over helical compression springs.

When a torque is applied to a spiral torsion spring, an angular displacement is created between the first and second loading points, the coil deflects (tightens), and the spring material is placed under stress, exerting a linear (to the degree of rotation) rotational "output" torque,  which drives the spring's rotation. Practically speaking, spiral torsion springs allow for lower torque loss, lower torque stress, and much greater reliability for use in valve and damper actuation.

Kinetrol Spring Return

Along with the inherent advantages of spiral torsion springs, additional benefits of the Kinetrol spring return unit are:

  • Separate housing for modular assembly, easily retrofitted
  • Sealed, non-breathing housing: Protects spring in corrosive environments
  • Adjustable pretension for 'balanced' air and spring stroke torques: Various combinations available for balanced / optimized torques at various air pressures
  • Keeper plates available to ensure safe handling of pretensioned springs
  • Available with ISO/DIN female drive and mounting
The combination of the spiral torsion spring reliability plus the advanced engineering design allow Kinetrol to offer a guarantee against failure of the spring unit for the lifetime of the mating actuator!

Vane Actuators Perform Better: Its All About the Gears (or Lack Thereof)

Why do vane actuators consistently outlast rack and pinion and scotch yoke actuators? The truth is in the gears.

Gears wear.

Surface wear, contact fatigue, scuffing and tooth bending are all real-life issues when dealing with gears. Surface wear affects gear contact in such a way that accelerates failure modes by increasing contact stresses and load distributions. This always leads to reduced accuracy and loss of smooth operation. Wear can never be completely eliminated, and over time, progresses at a more rapid rate.

rack and pinion
Typical rack and pinion design - note gear arrangement
Types of Stress on a Gear
  • Sliding stress - causes surface fatigue damage.
  • Rolling stress - causes contact fatigue damage.
  • Bending stress - like a cantilever beam, always deforms. 


rotary vane actuator
Vane actuator - no gears


Pure simplicity - the rotary vane.

One moving part. No gears.

The rotary vane actuator design is based upon a single moving part which eliminates gears required to convert linear motion to rotary motion. This simple and innovative concept provides an extremely reliable mechanism for operating valves, drives and dampers.

More Accurate Control

Another advantage rotary vane actuators have over rack & pinion and scotch yoke actuators is in smoothness and accuracy of control. The more mechanical connections the actuator has, the greater the cumulative hysteresis, and the lower the control responsiveness and accuracy.

For long, trouble-free performance, choose a rotary vane actuator for your next valve actuation or damper drive requirement. You'll be very glad in the long run. 

The ISO 5211 Valve Mounting Flange and Actuator Connection

Valve with ISO 5211 Flange
Valve with ISO 5211 Flange
ISO 5211 is a European standard that specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.

A standard interface between actuator, valve, solenoids, and positioners  provides many benefits. Actuated valve assemblies are installed in a very wide range of applications and operating conditions resulting in many custom designs. Understanding the connection between these components is critical for long life, safety, and performance.

A standard mounting / connecting device lowers inventory costs and allows for faster maintenance and repair. Standardization also allows for the replacement of brands, so long as both adapt to the standard. Finally, using industry standard adapters maintain consistent specifications and tolerances which improve performance by reducing hysteresis and mechanical wear.

Kinetrol manufactures an ISO adapter for its models 02, 03, 05, 07, 08 and 09 which allows for mounting ISO 5211 valves directly to standard Kinetrol double acting actuators.

20 Innovative & Elegant Engineering Improvements for Pneumatic Valve Positioners

Kinetrol AP Pneumatic Positioner
Kinetrol AP Pneumatic Positioner
on top of a Kinetrol Vane Actuator
A valve positioner is an instrument attached to a valve to ensure the valve is at a desired position of opening or closing as per the control signal. Positioners sense the valve position through a position feedback mechanism connected to valve stem. There are many types of valve positioners. Some utilizing pneumatic signals (referred to as pneumatic positioners) and some using electrical current as the signal (referred to as electro-pneumatic positioners). Many manufacturers stake claim over design and performance enhancements, but one pneumatic positioner stands out because of its elegant design. The Kinetrol AP Positioner.

The AP pneumatic positioner combines the smoothness and accuracy of Kinetrol’s proven mechanical positioner technology (using a proportional spool valve driven by a simple, accurate and robust force balance mechanism) with new advances in convenience and simplicity of use, derived from the unique innovative design both of the internal mechanism and of the overall package. 

The result is a positioner with unparalleled performance and real industrial robustness, sweet and easy to calibrate and characterize, and adaptable to the whole range of applications with its unbeatable list of options – high flow valves, direct mount or industry standard discrete mount housings, 4-20mA angle retransmit, limit switches, Clear Cone position monitor and I/P convertors (either simple or with various explosion proof options).

Tough Actuator Service on Paper Plant Green Liquor Line

Pulp and Paper Plant
Pulp and Paper Plant
It's said the only thing a pulp and paper plant doesn't reuse is the "shade the building casts". The processes used in the production of pulp and paper are very efficient when you consider the reuse of energy and by-products. The efficiency comes at a cost though - through very hostile atmospheres and demanding operating conditions for process equipment.

For example, the "kraft process" (also known as the sulfate process) is the method to convert wood chips into pulp and then to cellulose fibers. This is done by mixing the wood chips with sodium hydroxide and sodium sulphate, soaking, cooking and processing.

Here's a very basic explanation of the kraft process. Wood chips are soaked and processed in sodium hydroxide and sodium sulphate mixture known as "white liquor".  After the wood chips are impregnated with white liquor, they are then cooked in digesters to break the wood down into cellulose. The solid pulp is then separated and the remaining fluid is referred to as "black liquor". Black liquor is further processed to remove solids and chemicals which are to be re-used in the pulping process. One of the final by-products is "green liquor" which contains sodium carbonate and sodium sulfide and is then reacted with lime to regenerate more white liquor.

All of these steps expose process equipment, piping, and valves to very tough environments. Kinetrol actuators are preferred in these situations because they don't allow corrosive atmospheres to penetrate the actuator or springs, their long cycle life,  and their epoxy stove enamel finish.

Below is a picture of a Kinetrol model 14 double acting actuator on a 8” full-port ball valve on a green liquor line. The valve cycles 2 times per day to direct green liquor flow and weak wash (weak white liquor) alternatively from one pipe to another in order to prevent solids build up in the pipelines.

Keeping Critical Turbine Lubrication Flowing

Power plants generate power 24/7. Their generator turbines are constantly running.  Turbines require lubrication to protect against wear and also for cooling. Maintenance of the lubrication system is critical, and switching between two lube skids is a common way to perform maintenance without shutting down the turbine.

Two 3-way valves and pneumatic actuators are used to re-direct flow between between two lube filter housings. The valve and actuator must be extremely reliable as a failure requires the turbine shutting done.

Steam Turbine

The automated valves provides an “on-the-fly” ability to transfer turbine oil service between filters, allowing the unit to run, and maintenance to be performed on the filter not in service. This is an extremely critical service to protect the turbine.
