PTR251-090P-RA21M-C Brand Introduction

PTR251-090P-RA21M-C is Parker PTR series heavy-duty pneumatic rotary actuator developed for industrial rotary motion control system. It specializes in 90-degree angular rotation, torque output and position feedback for valve, clamping and flipping automation mechanism, matched with solenoid valve and PLC control system.

Pneumatic Rotary Actuator is the core unit of PTR251-090P-RA21M-C. Pneumatic Rotary Actuator adopts high-strength alloy housing, rack-and-pinion internal transmission structure for flange mounting. Pneumatic Rotary Actuator rated working pressure up to 250PSI, rotation angle 90°, built-in Hall effect position sensor for continuous angle feedback. Pneumatic Rotary Actuator converts compressed air power into stable rotary torque to realize fast and repeatable angular movement.

PTR251-090P-RA21M-C provides stable Torque for automation system operation. Torque maintains consistent rotary output in full stroke. Torque supports bidirectional rotation and adjustable cushioning at stroke ends to reduce impact. Torque integrates position sensing function to feed back real-time shaft angle for closed-loop monitoring.

PTR251-090P-RA21M-C features reliable Connection for air pipeline and control assembly. Connection uses standard pneumatic port for compressed air piping. Connection is compatible with Parker solenoid valves, limit switch modules and industrial PLC. Connection ensures stable air supply and position signal transmission in continuous cyclic operation.

PTR251-090P-RA21M-C is widely used in process ball valve actuation, packaging machinery, material handling, fixture clamping and legacy rotary automation system renovation. With mature Parker rack and pinion pneumatic technology, this rotary actuator adopts compact flange mounting and has high repeat positioning accuracy and long service life. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted industrial pneumatic rotary actuator solution.
