Rotating Pneumatic Actuators

Model Number

E-02

The rotary actuators are designed to operate rotating valves ball valve, v-notch ball valve, plug valve & butterfly valve for control as well as on-off service. Small size, up to ESD-160, ESA-160 are Scotch-Yoke mechanism which produces a torque curve that most closely match as the torque requirements of rotating valves. It produces great torque at the beginning and the end position of ball valves and butterfly valves.

Features
