Double 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. Supriya Hydraulic Manual Overrides for pneumatic single acting actuators provides a loweffort 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) | Supriya Emergency Shutdown Valve (ESD, ESV or ESDV) is designed to provide control of hazardous fluid pipeline valves or hydrocarbon gases pipeline valves based on detection of a dangerous at sensing point. Once the line pressure drops below the set point, an appropriate action is initiated against possible harm to people, equipment or the environment. |
| 2) | Suitable to fit volume tank and achieve fail safe strokes and fail safe position as per process requirements. |
| 3) | A variety of instrumentation, positioner, controller options, switch boxes, customized control panels makes this actuator ideal for a variety of process control applications. |
| 4) | 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. |
| 5) | Supriya actuators are built to provide long end efficient service with minimum maintenance. The design, engineering and materials used in their construction ensure optimum performance even in the hardest environments. |
| 6) | Our actuators are designed for 20years of service life. |
