Emerson Fisher Snappy Joe™ N562 Series Railcar Emergency Shutoff Valve w/ Excess Flow

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.

This product is backed by a 10 year warranty.

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.
