Quarter-turn pneumatic actuators are used for on-off or modulating control of any ball, plug, or butterfly valve using compressed air, natural gas, or nitrogen actuator supply Standard features All models available as double acting or spring return Torque outputs to 5,700,000 in lbf [644,000 N m]. Pneumatics Vs Hydraulics. Advantages. Pneumatic Systems are light in weight. For example, the controls are simpler, eliminating the complex system of valves, pumps, filters and sensors that make up hydraulic and pneumatic systems. Advantages of Pneumatics. Butterfly valves used as outlet valves on silos of powdered product can bind when the product causes the torque between the disk and seat to increase above the capacity of the actuator. Advantages & Disadvantages of Pneumatic Systems Two-Stage System. Article contributed by Kevin Hill, European product manager pneumatic actuators, Pneumatic Division Europe , Parker Hannifin Corporation. Disadvantages • Pressure losses and air’s compressibility make pneumatics less efficient than other linear-motion methods. actuators is extremely important to your process control. Typically, electric actuators are known for their high levels of precision while pneumatic actuators are considered less expensive and easier to maintain. Advantages & dis-advantages 3.
