Figure 3 - Two inch Mooney Flowgrid Slam Shut
regulator with over and/or under pressure protection.
A second sense port is optional.
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. Series 50D dual function controller (Figure 3), where each function provides either over- or
under-pressure shutoff protection and both functions are controlled by a common sense port
3. Series 50DS dual function controller (Figure 3 and 4), where each function is controlled by an
independent sense port. This allows two independent locations to be monitored for an over- or
under-pressure condition, each with its own set point.
A stand alone Slam Shut consists of a Flowgrid body with valve module and cover mounted on
top. The pressure controller is mounted on the side of the valve module.
