I. Overview

The PR P/S pneumatic light small angle actuator is a symmetrical arrangement of two pistons in one cylinder, moving towards each other; The thrust exerted by air pressure on the piston is transmitted to the central gear through the rack, forming a force couple. The output shaft integrated with the central gear outputs the angle and torque, which is a new type of pneumatic piston actuator independently developed by our factory; Compact structure, high output torque, reliable action This type of actuator has two structural types: PRS type spring return type (also known as single acting type) and PRP type springless type (also known as double acting type). It is equipped with a valve positioner and can achieve proportional adjustment. Therefore, it is widely used in angular stroke control valves such as ball valves and butterfly valves.
