Achieving Up to 4 Million Operations: The Efficiency of Kinetrol’s Rotary Actuator

Achieving Up to 4 Million Operations: The Efficiency of Kinetrol’s Rotary Actuator

Because of their direct influence on cost, safety, and efficiency, cycle life is a vital criterion when applying pneumatic actuators on industrial quarter-turn valves.

In terms of cost, frequent replacements or repairs of actuators can lead to higher expenses over time. An actuator with a longer cycle life might have a higher initial cost, but its extended operational lifespan can minimize the need for frequent maintenance or replacement. By reducing the frequency of replacements and potential system downtimes, plants can maintain a more steady production rate and avoid unexpected costs related to equipment failure.

Safety is paramount in industrial settings, and an actuator's cycle life plays a role here, too. Actuators that don't achieve their expected cycle life can fail unexpectedly, potentially leading to uncontrolled valve movements. Such unpredictable behavior can harm personnel, the environment, and other equipment. For example, if a valve doesn't open or close as expected because of an actuator failure, it could release hazardous materials or create unsafe operating conditions in the plant.

Efficiency is another area where the cycle life of an actuator is crucial. When actuators on industrial quarter-turn valves operate consistently within their expected cycle life, they ensure the valves open and close as intended, allowing for the precise control of fluid flows. This accuracy is critical for maintaining optimal process conditions. When an actuator is nearing the end of its cycle life and begins to underperform, it can lead to inefficiencies, such as inaccurate flow rates or incomplete valve closures. These inefficiencies can affect product quality, yield, and overall system performance.

Kinetrol's claim of up to 4 million operations for its rotary actuator isn't just a mere statistic; it's a statement of endurance, reliability, and superior engineering. This impressive feat provides engineers and plant maintenance staff with undeniable advantages in terms of cost savings, enhanced safety, and operational efficiency when operating industrial valves.

In essence, Kinetrol's commitment to pushing the boundaries with their rotary actuator's impressive operational capacity isn't just an engineering achievement. It's a boon to the industries that rely on such equipment. Through cost savings, heightened safety, and enhanced efficiency, Kinetrol's rotary actuator stands as a testament to how advanced engineering can profoundly impact industrial operations.

The Steadyline Series: Kinetrol's Answer to Ultra-Reliable Valve Actuation with Enhanced Valve Damping Features

The Steadyline Series: Kinetrol's Answer to Ultra-Reliable Valve Actuation with Enhanced Valve Damping Features

Rapid opening or closing valves in industrial process piping systems can lead to several problems. Here's a rundown of potential issues:
  1. Water Hammer: This is one of the most commonly known problems resulting from the rapid closing or opening of valves. Also known as hydraulic shock, water hammer occurs when a fluid's flow rate changes, causing a sudden increase in pressure producing shock waves that travel through the fluid in the pipes. The resulting forces can damage pipes, valves, and other equipment.
  2. Cavitation: This occurs when the pressure of a liquid drops below its vapor pressure, leading to the formation of vapor bubbles. When these bubbles move to an area of higher pressure, they collapse, causing localized shock waves, eroding the valves and pipes' material, and leading to premature equipment failure.
  3. Surge Pressures: Similar to water hammer but typically in systems with gases, rapid valve closure or opening can result in a pressure surge, damaging the system.
  4. Pump Issues: Rapidly closing a valve downstream of a pump can result in a sudden increase in pressure, which might cause the pump to work against a "dead head" condition, leading to overheating and potential damage to the pump.
  5. Instrumentation Errors: Rapid changes in flow rates can cause instrumentation reading errors, as many flow meters and sensors require steady-state conditions for accurate measurements.
  6. Process Upsets: Rapid valve actions can lead to unexpected changes in process conditions, potentially affecting product quality or even causing unsafe conditions.
  7. Noise: Fluids' sudden acceleration or deceleration can create noise due to vibrations. Over time, this can also contribute to material fatigue.
  8. Seal and Gasket Failure: The sudden change in pressure and flow can exert excessive stress on seals and gaskets, leading to premature failure.
  9. Mechanical Stress: The physical stress from rapid valve actions can weaken pipe supports, joints, and valve mechanisms.
A dashpot is a mechanical device that resists motion, often viscous friction, to dampen dynamic systems. Essentially, a dashpot is a damper that uses hydraulic or viscous friction to absorb energy, similar to how shock absorbers work in cars to smooth the ride. A dashpot rotary damping unit refers explicitly to a device that provides rotational damping.

Kinetrol's Steadyline pneumatic actuator assemblies are precision valve actuators, integrating their dashpot rotary damping units to provide smooth resistance to actuator/valve shaft rotation and individual customer requirements.

Kinetrol Steadyline assemblies smooth out the actuator's standard travel, dampen any flow-induced valve disc oscillations, and allow the user to specify a minimum travel time upon power failure.

Pneumatic Vane Actuators

Pneumatic Vane Actuators

A pneumatic vane actuator is a type of pneumatic actuator that uses compressed air to convert linear motion into rotary motion. It consists of a housing, a rotor with a vane that slides within the housing, and a shaft that connects the rotor to the valve or other device being controlled.

When compressed air is supplied to the inlet port of the actuator, it pushes the vanes outwards, causing the rotor to rotate. The rotation of the rotor is transferred to the shaft, which in turn moves the valve or other device. When the compressed air is released from the inlet port, air applied to the return port (or a spring) pushes the vanes back, returning the rotor to its original position.

Industrial pneumatic vane actuators are commonly used in various industrial applications, such as in process control, power plants, and HVAC systems, to control the flow of fluids, air, and gases. They are also used in oil and gas, water treatment, and chemical processing plants.

The advantages of industrial pneumatic vane actuators include their ability to provide precise control, high speed of operation, and ease of maintenance. They are also relatively inexpensive and widely available. Vane actuators are smaller and more compact compared to other types of pneumatic actuators, such as piston actuators, which makes them well-suited for tight spaces. A vane-type pneumatic actuator has only one moving part because it consists of a single vane that rotates within the housing. The vanes assembly is the only component that moves within the actuator, making it more reliable, and it requires less maintenance than other types of actuators with multiple moving parts.

Consider Space and Fit as a Cost Driver When Applying Actuation to Your Valves and Dampers

Being creative with the design and layout of automated valve packages, and paying attention to space, has significant impact on the total life-cost of an automated valve (or damper) package. Evaluating the footprint available, and then choosing components that will allow for simple installation and continued ease of maintenance, will pay dividends over the long term. Always plan your valve and damper automation systems with ample space for access to tools and service personnel.  Don't burden your maintenance staff with an over complicated or nightmarish actuation system that takes hours of preparation just to do routine maintenance. Also consider that easier access many times means greater safety.

Kinetrol pneumatic actuators, spring modules, and positioners are engineered with this in mind. Their efficient actuator design provides more torque in a smaller package and their bolt together, modular configuration, provides very significant space savings. The result is more power in a smaller space, along with easy access, and quick change-out.

As you can see from the image above, electrohydraulically powered valves and dampers (left) require pumps and motors. Pneumatic cylinder operated valve and dampers require mounting fixtures, linkages, and additional tubing. But you'll note the Kinetrol actuator and positioner (center) provides mounting directly to the valve/damper shaft. The automation is done cleanly and takes up substantially less space.

Pneumatic Actuator Application Guide for The Asphalt Industry

There are two main types of asphalt plants, batch and continuous. Batch plants are the most widespread and offer the greatest flexibility. Single batch mixes can be produced per each customer’s requirements. Individual components are weighed and metered separately every 50-60 seconds to produce a complete batch. Continuous plants produce single mix asphalt in large quantities without interruption. The production system is simplified, which reduces maintenance, but offers less flexibility.

The following Application Guide concentrates on batch plants, although similarities exist between both.

You can read the guide below, or download it from Kintrol USA'a site here.

  • Limit switches
  • Clear Cone position monitor
  • I/P convertors (either simple or with various explosion proof options)
Kinetrol's AP pneumatic positionerOPERATING PRINCIPLES

The AP positioner is designed to drive a rotary or linear actuator to a position set by a 3-15 psi (0.2-1.0 bar) signal and hold it there until the signal changes.

When a signal pressure is applied to the diaphragm it moves the force balance lever clockwise against the tension of the feedback spring. This moves the spool valve, supplying air pressure to one side of the actuator while exhausting trapped air from the other side. The feedback shaft follows the movement of the actuator and turns the cam counter clockwise, pushing the cam follower and increasing the tension on the feedback spring until it balances the force on the diaphragm and moves the spool valve to its central ‘hold’ position.

The relationship between the input signal and desired position (the ‘characteristic’) is determined by the cam profile. A linear 3-15 psi (0.2 - 1.0 bar) signal / 0-90° output movement cam is standard. Split range, fast opening, equal percentage or customized characteristic cams are available.

Review: Vane Actuators

vane actuator
An internal view of a vane actuator allowing you
to see the one piece vane and shaft, lip seals,
travel stops, and the clam shell  design.
The vane actuator is a simple and elegant mechanism for quarter-turn valves, dampers, and other rotary motion applications. The vane actuator produces rotary motion through the application of air pressure to a "vane' attached directly to an output shaft. In higher quality vane actuators, the vane and shaft are machined from a single piece of steel. Because of this, any motion from the vane is transferred directly to the shaft, without backlash or lost motion.

The vane includes “lip seals” that isolate the vane and shaft from the air supply. The lip seal design provides several advantages, namely eliminating the need for shaft seals and an inherent cleaning action internally. A split, or “clam-shell” housing is assembled around the vane, totally enclosing it. When supply air is applied to one side of the vane, torque is produced moving the vane in one direction. Accordingly, there is direct rotary motion transfer to the shaft, with 100% efficiency. Torque is controlled by surface area of the vane and the differential pressure on either side of the vane. Bi-directional over-travel is limited by the use of travel stops mounted in both sides of the housing.

The Kinetrol Vane Actuator
The Kinetrol Vane Actuator
Single acting vane actuators use a spring to return the actuator to its resting position. By adding a spring, vane actuators can fail-open or fail-closed in the event of power failure. Double acting actuators use supply air on either side of the actuator to dictate clockwise or counter-clockwise movement. Other types of pneumatic actuators generally require high quality air as their power source, but vane actuators can accept poorer quality supply air, as the vane design uses the vane’s “wiping action” to push dirt and grime out of the way. Vane actuators are generally more compact that other types of actuators and come in many sizes, producing a wide range of torques.

There are three areas where automated valves are required: 

1) Steam control valve
2) Vacuum pump valve
3) Chemical flow control valve

The steam line at one plant was unreliable and very expensive. It was costing the plant about $4000. To help come up with a better, more economical solution, a  Kinetrol USA Distributor was invited in and specified a Kinetrol actuator, positioner and custom brackets for the existing steam line valve.
