The 536 Pressure Reducing Valve from Arrow Valves is designed to provide a constant outlet pressure
Price range: £140.00 through £400.00 £168.00 inc. vat
Description
The 536 Pressure Reducing Valve from Arrow Valves is designed to provide a constant outlet pressure despite varying inlet pressures. The outlet pressure is adjustable between 0.5 and 6 bar. The inlet pressure must be higher than the desired outlet pressure. The outlet pressure is factory set at 3 bar and adjustments can be made at any time by removing the tamperproof disc on top and inserting the hexagon key (supplied). Turn clockwise to increase the pressure. A pressure gauge is supplied with each PRV (DN65 has two gauges), which indicates the outlet pressure. This may be removed and a plug fitted (supplied) or a self-seal probe test point can be supplied. Two gauge ports are provided to allow right and left configurations. This direct acting PRV may be installed in horizontal or vertical pipes. Flat-faced unions enable the valve to be quickly installed and orientated and a range of connections is available to suit various pipes.
