"Failure Is Not an Option" - Kinetrol Manual and Fire Fail-Safe Spring Units

Kinetrol Fail Safe Spring Return Handle

If you want to operate a valve manually, but maintain the advantage of the fail-safe spring's certainty of position when unattended, check out the Kinetrol's manual and fire fail-safe spring handle. This uniquely designed manual operator offers some compelling benefits in automating valves and provides additional plant safety levels. Spring return (also known as "deadman") handles will help you meet individual plant safety requirements and OSHA requirements for valves that must return to the closed position after an operation. Unlike lever handle or gear operators that will leave the valve in the last state, the spring return deadman device ensures that the valve returns to its original starting position powered by the associated spring handle.

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.

How To Install and Remove a Kinetrol Actuator Spring Unit

This video demonstrates how to install and removed a spring unit for a Kinetrol vane actuator. Spring units are available for either clockwise or counter clockwise spring action. They are mounted, as standard, between the actuator and what it drives. With spring units alone, direction is determined by looking at the unit from the end which interfaces with the actuator.

Permanent mold casting (PMC) is a metal casting process that employs reusable molds, usually made from metal. Common permanent mold casting casting metals are aluminum, magnesium, and copper alloys. Other materials include tin, zinc, and lead alloys and iron and steel are also cast in graphite molds. The permanent mold process has a number of advantages over other casting techniques. Benefits of permanent mold casting are:
  • No waste from the mold
  • Reusable mold
  • Good surface finish
  • Good dimensional accuracy
  • High production rates
  • Higher conductivity levels
Kinetrol actuator
Kinetrol actuator replacement. The actuator mounts directly to equipment,
connected directly to the shaft eliminating the need for rods and yokes.
A foundry in the North Central USA was using a hydraulic cylinder to continuously position an armature on each side of a piece of foundry equipment. The movement of the cylinder and associated hardware was limited to 60 degrees of rotation for the application. The mounting style and location of the hydraulic cylinder made it very difficult to access and adjust. To make things worse, the cylinder design and it's associated rods and yokes compounded the need for adjustment due to wear.

The local Kinetrol Distributor was called in and immediately saw the opportunity to replace the hydraulic cylinder, rods, and scotch-yokes with a Kinetrol actuator and simple mounting.

The Kinetrol actuators have been working for several years now, moving continuously without problem and eliminating the need for frequent adjustments.

Upgrade in Steam Balancing Valve Actuators at Combined-cycle Power Plant Lead to Kinetrol

The customer for this application note is an electrical power station with a combined-cycle, natural gas-fired generating unit with two combustion turbines, two heat recovery steam generators and one steam turbine. The output of combustion turbines can vary at different times throughout the year. The nominal output for this facility is 577 megawatts. The station burns natural gas.

A combined-cycle power plant uses a gas and a steam turbine together to produce up to 50% more generated electricity, using the same fuel, when compared to a traditional simple-cycle plant. The gas turbine waste heat is routed to the nearby steam turbine which, in turn, generates the extra power.

One of the most common components for managing high-pressure steam in a combined-cycle plant is the HRH bypass valve (HRH stands for "hot reheat"). Since the valve actuator controls the valve’s ability to reliably and accurately respond to system demands, it can be argued it is one of the most important elements in the steam bypass system, and therefore the entire combined-cycle plant.

In this application, the customer had two 18" steam balancing valves using large, high torque, scotch-yoke actuators that had to cycle 20 times a day. These actuators presented significant performance issues (they were failing), plus they were very large which presented maintenance difficulties.

The customer approached the local Kinetrol USA Distributor and inquired if they could suggest a better alternative. The goal was to provide replacement actuators that provide very high torque, be highly reliable, and save space.

The Distributor recommended Kinetrol Model 30 pneumatic rotary actuators. The Model 30 provides 168000 lbf ins (19140 Nm) at 100 psi (7 bar) of torque and were significantly smaller and lighter than the legacy scotch-yoke actuators. Most importantly, they carried the world-renowned Kinetrol reputation for outstanding reliability, long life, and maintenance-free operation.

An insurance mandate required a major chemical company who produces PTA (Purified Terephthalic Acid) to install a 20" automatic high performance butterfly valve with the capability to stroke from fully opened to fully closed in less than one second.

Requirement:
It's necessary to prevent a $30M USD axial process air compressor from rapidly going into an overspeed condition that could harm equipment, infrastructure, and personnel. 

Challenge:
20" high performance butterfly valve with Kinetrol actuatorThe biggest challenges: stroking the valve in under one second, but without slamming the butterfly disc into the stops which can damage the valve and nearby equipment. 

Solution:
Kinetrol's expertise in rapid cycling enabled us to size, select, and perform certified cycle time tests on the final assembly. This shut out any competition. 

Assembly: 
20" class 300 high performance butterfly valve, Kinetrol 207-120 with a 2" automatic L-Port, 3-way, compressed air supply ball valve with 097-F120, X-proof solenoid, and two exhaust silencers coupled to the size 20 supply port. Open / closed limit switch assembly. Robust SST mounting bracket and coupling. The closure time once actuator air is exhausted: 0.13 seconds.


 

Challenging Steam Balancing Valve Application at Southwest Power Plant

Steam Balance Valve
Steam balance valve
with Kinetrol model 30.
In combined-cycle power generation plants, the most common design for managing high-pressure steam is with cascading bypass systems. Balancing valves are used on the hot reheat line to respond to control loop demands. The application is difficult because of high pressures, high temperatures, and large valve sizes (high torque). The valves must shut off tightly and also be capable of precise throttling.

Outfitting these valves with pneumatic actuators is also difficult. Because of the valve size and valve design, actuators must have high torque output, without taking up vast amounts of space. The actuators must also act quickly and eliminate hysteresis.

Most pneumatic actuator designs simply cannot meet the operating and size restrictions, and hydraulic actuators, with all of their associated maintenance problems, are used instead.

A Kinetrol Distributor in the Southwest USA was asked to recommend a better alternative to a line where very large scotch-yoke actuators controlling two (2) 18" valves were controlling poorly and were taking up too much space.

The Distributor's challenge was to:
  • Deliver very high torque output.
  • Provide as small a package as possible.
  • Improve the actuators stability and reliability.
The solution was to apply Kinetrol model 30 vane actuators. The model 30's deliver 168,000 lbf (at 100 psi) of torque in a compact envelope (comparatively). Additionally, the Kinetrol Model 30's, combined with third-party digital valve positioners, provided the precision and response the application required to eliminate oscillations and instability.  The actuators cycle about 20 times per day and have been performing without problem for years. Huge annual fuel savings can be directly attributed to the actuators reliability and precision due to fewer turbine restarts.
