A pressure reduction valve can be a valuable addition to many piping systems. If the incoming water pressure is too high, this can put unnecessary strain on water heaters, pipe work, plumbing joints, taps and tap washers. It can increase the risk of burst hoses on washing machines, water leaks and possibly magnify any existing water hammer problems. The AVG pressure reduction valves (PRV) are factory set at 500 kPa. The downstream pressure is adjustable from 250 to 650 kPa. For pressure monitoring, there is a gauge port on the body of the valve so that a gauge can be fitted to monitor the upstream and downstream pressure. Sizes DN15, DN20 and DN25.

The Bermad Model IR-430 Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure; when installed as a relief or circulation valve, it relieves line pressure in excess of preset.
