The Role of Industrial Valve Actuators
Thanks to actuators, multiple valves can be controlled in a process system in a coordinated fashion; imagine if, in a large industrial environment, engineers had to physically adjust every valve via a hand wheel or lever! While that manual arrangement may create jobs, it is, unfortunately, completely impractical from a logistical and economic perspective. Actuators enable automation to be applied to valve operation.

Pressurized-liquid reliant devices are known as hydraulic actuators. Electric actuators, either motor driven or solenoid operated, rely on electric power to drive the valve trim into position. With controllers constantly monitoring a process, evaluating inputs, changes in valve position can be remotely controlled to provide the needed response to maintain the desired process condition.
Manual operation and regulation of valves is becoming less prevalent as automation continues to gain traction throughout every industry. Valve actuators serve as the interface between the control intelligence and the physical movement of the valve. The timeliness and automation advantages of the valve actuators also serve as an immense help in risk mitigation, where, as long as the system is functioning correctly, critical calamities in either environmental conditions or to a facility can be pre-empted and quickly prevented. Generally speaking, manual actuators rely on hand operation of levers, gears, or wheels, but valves which are frequently changed (or which exist in remote areas) benefit from an automatic actuator with an external power source for a myriad of practical reasons, most pressingly being located in an area mostly impractical for manual operation or complicated by hazardous conditions.
Thanks to their versatility and stratified uses, actuators serve as industrial keystones to, arguably, one of the most important control elements of industries around the world. Just as industries are the backbones of societies, valves are key building blocks to industrial processes, with actuators as an invaluable device ensuring both safe and precise operation.
Pneumatic Vane Actuators Can Now Be Used in Foodservice Wash-down Applications
Kinetrol Blueline Foodservice Actuator (Double-acting) |
Finally, food and beverage processing companies can take advantage of the long-life and headache-free performance of Kinetrol vane actuators.
Kinetrol USA has officially introduced it's "Blueline" Series of pneumatic vane actuators for use in foodservice and beverage processing. The actuators are intended to be installed in areas where harsh chemical wash-down is required. These areas are very tough on most types of pneumatic actuators because the caustic or acidic chemicals used in cleaning adversely effect the actuator. All stainless steel actuators are an alternative, but they are prohibitively expensive. Kinetrol's Blueline Series provides a very economical option.
Kinetrol Blueline Actuator (Spring-return) |
The Blueline Series provides food and beverage processors all the time-proven benefits of the Kinetrol PLUS provides an affordable option for tough chemical wash-down areas.
Kinetrol Blueline Features:
- Very good resistance to "caustic wash-down" procedures as typically performed in the food industry.
- Very good resistance to corrosion In salt laden environments.
- Very good non-stick properties.

Rotary Vane Actuators for Corrosive Marine Environments: The Right Choice
Corrosive marine environments present problems for valve actuators. |
Rotary vane actuators, (such as Kinetrol) provide strong immunity to internal corrosion. First, they have no internal gears or springs to corrode. Second, the internal surfaces are coated with a very durable, epoxy enamel finish and all internal hardware is made from stainless steel. Additionally, the “wiping” action of the vane and lip-seals provide a self-cleaning effect that prevents corrosion in the working areas. Finally, unlike rack & pinion and scotch-yoke actuators whose coil springs are bathed in ambient air, (Kinetrol) vane actuators use externally mounted clock type springs that are 100% sealed from ambient air/gasses and are unaffected by corrosive atmospheres.
For any application where corrosion is a problem, such as those in offshore platforms or other marine facilities, engineers should strongly consider rotary vane actuators as the preferred choice for any quarter-turn valve application.
The video below illustrates the difference in construction in actuator types and illustrates the inherent advantages of vane style actuators:

Cement Silos Need Valve Actuators with Power and Reliability
Kinetrol spring return actuator on cement silo valve. |
One particular cement processing plant needed a replacement for their main silo off loading valves. These valves fill cement trucks the company used to deliver their product.
The plant's existing valves were poorly applied for this use and were causing major headaches. The valves were designed with thin steel plate, large gaps between the valve body and disc, and rubber seals that wore away, leading to cement leaking through the valve. The leaking cement would spill onto a feed trough where it would cake and require manual cleaning - an expensive and time consuming operation. If the valve didn’t leak, this expense and time would be saved.
A custom valve manufacturer was called in to use their engineering and fabrication expertise to develop a custom valve that would last. The result was a new rotary valve that uses a much hardier wear plate, and the rotor and body are carefully machined with only a 2/100ths of an inch gap between them. Additionally, the design provides a mechanism to catch any cement should any ever make it through the gap.
The new, custom designed valve needed an actuator that would be equally reliable. The selection of Kinetrol vane actuator with a spring return was the most obvious because its power and its reliability. With only one moving part and no complex linkage to wear out, it was the best choice for long life. The combination of valve and actuator is expected to last many thousands of operations with no maintenance.
Procedure for Calculating Distance of Actuator from Hot Valve
The purpose of this post is to assist in determining the proper distance of a Kinetrol actuator from a hot valve.
In many situation, valves are put inline with a hot process media flowing through the piping system. In these situations, careful consideration must be taken to avoid over temperature exposure of the Kinetrol actuator via conductive or radiant heat.
The following formulae will assist in giving you data to calculate the safe distance between hot valve and actuator.
If you need assistance, or have any concerns about properly distancing the actuator from your process, it's always best to consult with the experts at Kinetrol USA. They're just a phone call away. For more information visit www.kinetrolusa.com or call 972-447-9443.

Kinetrol + Plug Valve = Optimum Sludge Valve Performance
Water treatment plant |
Many valve manufacturers specify high-pressure/high-torque actuators to overcome the sludge. Many times they choose linear type valves and screw-type linear actuators because they provide the brute force needed to push through the sludge. An unwanted side-effect of using linear valves and actuators is that the same force used to push the disc through the sludge, also causes valve damage by pushing and grinding solids into the valve seats, disc and seals. Eventually, the valve becomes so damaged it no longer provides proper shut-off.
Kinetrol actuator |
For sludge applications, Kinetrol rotary vane actuators mounted on quarter-turn plug valves are a great choice . The combination of the high cycle actuator design, with the design benefits of a plug valve, offer wastewater treatment operators a valve assembly that will provide years of trouble-free life.
Warehouse Palletizers Rely on Kinetrol Actuators for Trouble-free Performance

Palletizer with Kinetrol Actuators |
One component is the palletizer subsystem. The palletizer subsystem provides automatic stacking of products on top of a pallet.
More sophisticated palletizers have complex control systems to provide the speed, accuracy and control required for large scale operation. The control systems are made up of computers, PLCs, proximity devices, and optical instruments. For product movement, transfer, and placement, palletizers rely on highly accurate pneumatic, electro-pneumatic, and electro-hydraulic motors, actuators, and drives.
Palletizer in plant. |
Because of their high cycle life, smooth movement, precise control, and maintenance free operation, Kinetrol vane actuators have been very successfully used by palletizer OEMs. The actuator provides 90 degree and 180 degree rotation on the vacuum gripper head and pivot arms. During normal operation the Kinetrol actuators can see upwards of 20,000 cycle per day.

Superpulsator Vent Valve Operation Demands Performance
Kinetrol on Superpulsator Vent Valve |
A Superpulsator unit is a simple type of clarification system utilizing an upward flow tank and inclined plate settling. It operates by varying the level of the flocculation tank through the use of a vacuum pump and vent valve. The pump creates a vacuum in the tank causing the water level to rise. A vent valve then opens to atmosphere causing the water level to fall. The valve is then closed, and the process repeats itself continuously. The actuated vent valve is controlled by a timer set to pre-defined vacuum and vent cycles.
A Kinetrol USA Distributor was called in to assist in a water treatment plant’s upgrade to superpulsators. After reviewing the application, the Distributor specified 4" plug valves actuated with Kinetrol vane actuators and Kinetrol ULS limit switches. The plant’s original system was using double acting, air cylinder operated valves. These had to be replaced because they wouldn't be able to withstand the superpulsator's constant vacuum and venting cycling. The more robust Kinetrol actuator, capable of very high cycle rates, was clearly the best choice.
After installation and startup, and several years in operation, the Kinetrol actuators are performing flawlessly and are providing maintenance-free operation.
20" High Performance Butterfly Valve Closed in Under 1/2 Second!
Fast closing Kinetrol actuator |
You'll note the valve takes about 11 seconds to open, but only 0.4 seconds to close, using the Kinetrol spring return unit.
Quick closing valves are used in emergency situations to stop the flow of fluids that may contribute to uncontrolled combustion, cause backstream contamination, or allow spillage of hazardous materials.
1/4 Turn Electrohydraulic Valve Actuators
A hydraulic gear pump immersed in its own reservoir delivers pressurized oil to the vane-type 90° actuator via the control box, which contains non-return valves and solenoid valves to direct the flow into the actuator; with cam operated limit switches to control travel and (optionally) signal position to the user. The unpressurized side of the actuator is connected to the reservoir, so there is no net transfer of oil from reservoir to actuator. The pump and its motor run entirely on precision ball bearings, so that the friction and motor size can be minimized and life maximized; the efficiency resulting from this reduces the heating effect and allows 100% rating. A pressure release valve is built into the pump so that if the actuator load becomes jammed the torque is limited and dangerous over pressures or motor stalls are avoided.
Fail-safe spring return action uses a reliable low-stress-range sealed clock-type spring unit mounted coaxially with the actuator, together with a fail-open solenoid valve, to ensure reliable positioning when power is not supplied to the unit. A high flow external dump valve can be fitted to allow very rapid spring-driven action.
Double-acting models are supplied with solenoids arranged to give position locking when power is disconnected. An optional manual by- pass valve is available to allow manual override movement of a double acting when power is disconnected.
The interface between pump/reservoir unit and the control box allows mounting of the pump in different orientations at 90° to each other, so that the motor can be kept above the reservoir whether the actuator output axis is horizontal or vertical. External electrical connections are all made via a single accessible connector block in the control box, with the simplest possible switching needed to drive the unit. Two conduit entries are available, to allow easy separate connection of power and signal lines (if used). All internal wiring is connected via a central connector and fuse board, and the actuator is protected from supply surges by a metal oxide varistor suppressor.
