Single acting linear pneumatic actuators are used for on/off or modulating control of any knife gate, wedge gate, globe or pinch valve utilizing compressed air, natural gas or nitrogen actuator supply. Hydraulic Manual Overrides for pneumatic single acting actuators provides a low-effort and high-thrust compact sized override for manually operating the actuator. The Hydraulic Override is a self-contained system for manual operation of pneumatic actuators. The unit consists of two main components, the hydraulic cylinder and the pump/reservoir assembly.

| 1) | Periodic maintenance is easy to perform since the spring return actuator only requires the removal of three-four parts to access all internal parts. |
| 2) | A variety of positioner, instrumentation, controller options makes the spring return actuator ideal for a variety of process control applications. |
| 3) | Using standard O-rings and seals for both static and dynamic sealing makes Supriya spring return actuator soft parts lower cost and easier to find. |
| 4) | Our highly engineering springs with stronger materials and better surface treatment and finish provides exceptionally long fatigue life. |
| 5) | Our actuators are designed for 20years of service life. |
