Hydraulic Cylinder

Hydraulic Actuators

This type of actuator is used exclusively for rotary valves. The edge of the diaphragm is free, and by attaching a ring, the linear motion of the actuator is converted to a smooth rotational motion in the valve stem. Model 280 is a multiple spring type with four or six small internal springs, while Model 400 is a single spring type with one large spring. Both models are actuators that feature friction-free operation, excellent efficiency, and high output.
