This 1-1/2 in lead-free water pressure reducing valve is designed to reduce incoming water pressure to protect plumbing systems and reduce water consumption for commercial, industrial and residential applications. The easy maintenance assembly consists of a replaceable seat module, NPT threaded female union inlet by NPT female outlet and a bypass feature to control thermal expansion pressure. The temperature range is 33 to 180 deg F (0.5 to 82 deg C). Suitable for up to 300 psi (20.7 bar), the pressure range can be adjusted from 25 to 75 psi (172 to 517 kPa) with the standard setting at 50 psi (345 kPa).
