FW Murphy M5081FS-B: 2" Natural Gas Shutoff Valve; 24VDC, Normally Closed, 24 Volt DC Coil; Aluminum Body.  (55700016)

This fuel shutoff valve is a semi-automatic device for shutdown of natural gas-fueled engines. The valve is opened manually and closes when the electromagnet is energized and trips the latch. The valve can be closed manually by turning the disconnect knob.  A vent in the valve body relieves trapped gas when the valve closes. A pop-out indicator button informs you when the valve is open or closed.

The valve’s tripping power is provided by an engine ignition system or battery.

The M5081FS_B is a 2-inch (51 mm) valve with two NPT connections. It has two SPDT snap-switches. The valve body is aluminum.

It also has a normally energized circuit. This circuit allows the valve to be held open electrically and close by interruption of the coil’s power circuit.
