Belgas 627SX High Flow Slam Shut Valve

The Belgas P627SX is a high flow slam shut valve that closes in an overpressure condition. This overpressure protection device can be a standalone unit or used in conjunction with another regulator. The P627SX complements a pressure-reducing regulator which controls pressure/flow at a pressure condition. At the same time, the P627SX will shut off the flow at a preset pressure condition and remain closed until manually reset.
