Pressure Reducing System
with "Watchdog" Hydraulic Backup Valve and Low-Flow Bypass
Construction
Hydraulically operated, diaphragm actuated pressure reducing system, consisting of a BERMAD 720 PRV, an integral “Watchdog” backup valve and a DPRV. The system reduces a high upstream pressure to a lower, constant downstream pressure, regardless of fluctuating demand or varying upstream pressure. The “Watchdog” backup valve is fully open in normal operation. Should pressure rise downstream of the BERMAD 720 because of valve failure, the “Watchdog” quickly responds and triggers an alarm, while providing stable pressure to consumers until the PRV is repaired. The model also includes a low flow bypass regulated by a Direct Acting Pressure Reducing valve mounted on the valve body.
