4″ ANSI 300 Stand Alone Slam S
Item Code: SA-40-ANOWG
The Slam Shut valve is an easy to maintain automatic emergency shutoff device. The Slam Shut is designed for use with a pressure reducing regulator to provide secondary downstream pressure
protection. The device is designed to shut off the flow of gas when the sense or downstream pressure in the system either exceeds or drops below the set point pressures. It can be used as a stand alone device or integrated with the 1 inch Flowgrid regulator. The 1 inch Mooney Slam Shut valve consists of a valve body with a bleed plate and cover mounted on top, and a Slam Shut actuator assembly mounted on the bottom of the body. The 1 inch Mooney Flowgrid Slam Shut also has a throttle plate, diaphragm, and main spring.
