AVG Non Return Isolation Pressure Reduction Valve Combination 250kpa-600kpa

A non return isolation pressure reduction valve (NRI-PRV) 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 valves are factory set at 500 kPa. The down stream pressure is adjustable from 250 to 650 kPa by turning the screw on top. Clockwise to increase pressure and anticlockwise to reduce pressure. For pressure monitoring, there are three gauge ports standard on the body of the valve so that a gauge can be fitted to monitor the upstream and downstream pressure.

The tagging eye has been cast into the NRI-PRV body to allow the valve to be identified and tagged for mechanical service.
