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 aluminium.

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