P327C Pneumatic Cylinder Actuator
Type P327C pneumatic cylinder kits permit opening and closing Emerson N550 Series Snappy Joe® emergency shutoff valves (ESVs) from a remote location. The cylinder opens the valve when pressure is applied.

Upon loss of pressure, the N550 closes, assisted by the spring in the pneumatic cylinder. A bellows covers the cylinder rod to prevent build-up of foreign material around the rod, and a filter in the cylinder vent keeps out dust. All necessary installation hardware for the P327C is furnished.

Image shows a Type P327C installed on a N550.
