Type N550 "Snappy Joe" Emergency Shutoff Valves are designed for in-line installation. The valves provide a means of shutting off vapor or liquid in the event of a hose rupture or piping break at the transfer area. In this way large scale loss of LP-gas or NH3 can be avoided. Valves are manually opened and can be closed manually at the installed location or remotely by either cable (standard) or optional air control mechanism.

High Flow Capacity - The main poppet moves completely out of the flow stream to permit extremely low restriction to flow. For example, the 2" body size flows 70 gpm at 1 psig pressure drop.

Cable Release - Standard Snappy Joes are fitted with a release mechanism for cable attachment. Connecting a cable to the wire loop allows the valve to be closed from a remote location.

Fusible Element - The fusible element is located at the hub of the operating lever and stub shaft. If exposed to fire, the element melts and allows the stub shaft to turn. The poppet then moves to the closed position, even in cases where the operating lever has been wired open.
