Emerson Fisher N562 Series Emergency Shutoff Valves (ESVs) are designed for railcar protection and attach to the shutoff valves on railroad tank cars. Typically, three Type N562s are used: two on the liquid lines and one on the vapor line. Pneumatically operated, the valve is opened and closed by means of a standard quick-disconnect coupling. Remote closure from one or more points is accomplished by exhausting pressure from the valve's piston chamber with a pneumatic control valve.
Note: Type N562 ESV integrates shutoff valve with an excess flow protection to automatically close if flow exceeds 200 GPM (757 LPM propane at 13 psid / 0.90 bar d.
