PLD Series
PLD SeriesThe PLD Series actuators are engineered for high-performance and reliability in various industrial applications.
PLD Series piston actuator is designed for high-performance applications, ideal for ON/OFF or control functions in valve automation. The cylinder sizes range from 4 inches to 38 inches, making it a versatile solution for various valve types. It is especially well-suited for globe control valves due to its high thrust capability, stiffness, precision movement, and superior frequency response. The actuator offers bore sizes from 100mm to 980mm, with thrust forces ranging from 430 lbf to 97,500 lbf in the double-acting configuration. For single-acting applications, the thrust force depends on the spring selection. Manual override options are available via hydraulic cylinders or gearboxes for smaller sizes. Additionally, the actuator can be equipped with pneumatic accessories such as limit switches, solenoid valves, and positioners for enhanced functionality.
