Meeting your needs for downstream pressure protection GE Oil & Gas has drawn upon our leading product technology and application expertise to develop the Mooney Flowgrid Slam Shut regulator. The Slam Shut regulator provides accurate, reliable secondary downstream pressure protection by shutting off the flow of gas when the sense or outlet pressure in the system either exceeds or drops below the set pressure point. The device can stand alone or be integrated with a Mooney Flowgrid regulator.
1-inch Flowgrid Slam Shut regulator The 1-inch Slam Shut is a safety shutoff regulator that closes with a linearly acting plug. The device has bubble-tight shutoff under all rated conditions and requires no minimum differential for full shutoff. Set points are adjustable and repeatable regardless of flow rate, inlet pressure, and temperature variations.
2-inch to 4-inch Flowgrid Slam Shut regulator The controller assembly for the Slam Shut can be supplied with either over- or under-pressure shutoff protection in three basic interchangeable configurations: 1. Series 50 single function controller (Figure 2), which provides either over- or under-pressure shutoff protection. 2.

Principle of Operation for 2-4 inch Slam Shut During normal operation the latch mechanism holds the closure element (flapper) open as shown in Figure 5. The sense or downstream pressure is monitored by the over-pressure and under-pressure controller diaphragms, which convert the sense pressure into a force proportional to the pressure. The force is counter-balanced by the set point adjustment spring located in the spring case.
