The Kinetrol rotary vane design is based upon a single moving part which eliminates additional parts required to convert linear motion to rotary motion. This simple and innovative design provides a highly accurate and extremely reliable actuator for operating valves, drives and dampers, and is perfectly suited for the most demanding process control applications.

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

Kinetrol actuator replacement. The actuator mounts directly to equipment, connected directly to the shaft eliminating the need for rods and yokes. |
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

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.

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.

Challenging Steam Balancing Valve Application at Southwest Power Plant

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.
