25AUB-Z3 3/4 Water Pressure Reducing Valve with NPT ConnectionsSeries 25AUB-Z3 water pressure reducing valves are designed to reduce incoming water pressure to a sensible level to protect plumbing system components and reduce water consumption. This series is suitable for water supply pressures up to 300psi (20.7 bar) and may be adjusted from 25 Ã- 75psi (172 Ã- 517 kPa). The standard setting is 50psi (345 kPa). All parts are quickly and easily serviceable without removing the valve from the line. The standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply.Watts 0069717 Features:Standard construction includes Z3 sealed spring cage and stainless steel corrosion resistant adjusting and cage screws for accessible outdoor or pit installationsUnion inlet connectionIntegral stainless steel strainerReplaceable seat moduleBronze body constructionServiceable in lineBypass feature controls thermal expansion pressureHigh temperature resistant reinforced diaphragm for hot waterWatts 0069717 Specifications:Length: 6-7/8Material: BronzeConnection Size: 3/4Connection Type: NPTWeight: 2.95 lbs.
