Pressure Reducing & Sustaining Valve
823
800 Series
Waterworks
Hydraulically operated control valve with independent Pressure Sustaining and Pressure Reducing functions. It sustains minimum pre-set upstream pressure, regardless of fluctuating flow or varying downstream pressure, and it prevents
downstream pressure from rising above maximum pre-set level, regardless of fluctuating flow or excessive upstream pressure.
