PNEUMATIC CYLINDER LINEAR ACTUATOR
The PROVAL Cylinder actuator designed for a wide range of globe valves. PROVAL Cylinder actuator uses in control or on/off services. Actuator’s thrust capacity is much greater than similar size diaphragm type actuator because of air pressure as high as 700Kpa (7bar) being used.
PROVAL Cylinder actuator operates either as a single acting or double acting type. Positioner is usually mounted on yoke. Double acting type actuator has a two air connection. The cylinder actuators provide the operation to control the valve travel balancing between the force on the piston by the sigal air pressure, and the spring force.
By combining positioner, the actuator brings about high accuracy of positioning.
FEATURES
- · High thrust capability
- Cylinder has higher thrust force than similar size diaphragm.
- · Long service life
- · Long stroke
- It is possible to apply long stroke up to 8 inch
- · Adjustable actuating force to suit different application.
