PSP EV-400 3-Way Valve

The Model EV400 is an all mechanical, earthquake activated, 3 way - 2 position pneumatic valve. This valve, when used in conjunction with a spring fail pneumatic actuator, can be used to cut off the supply to almost any piping system during a seismic event. Mounting is accomplished using the two ¼”-20 UNC mounting holes, and the attached leveling chain. Using compressed nitrogen, or clean and dry compressed air (regulated to 80 psi) the Model EV400 can control just about any pneumatic control valve.
