Watts Regulators Water Pressure Reducing Valves Series 25AUB-Z3 1/2 (0068524)Watts Water Pressure Reducing Valve 25AUB, Water Pressure Reducing Valves Sizes: 1/2 to 2 (15 to 50 mm) With integral strainer Series 25AUB water pressure reducing valves are suitable for initial water pressures up to 300 psi (21.09 bar) and can be adjusted from 25 to 75 psi (172 to 517 kPa) delivery pressure to the system. The standard setting is 50 psi (345 kPa). They are standardly furnished with a bronze body, union threaded female inlet and female threaded outlet connection, stainless steel seat and strainer. All parts are easily and quickly serviceable without removing the valve from the line. The built-in by-pass prevents buildup of excessive system pressure caused by thermal expansion. A water saving test program concluded that reducing the supply pres-sure from 80 to 50 psi (551 - 346 kPa) resulted in a water saving of 30%. FEATURES: Union inlet connection, Integral stainless steel strainer, Renewable seat module, Bronze body construction, Serviceable in line.

Bronze Body. Sealed Spring Cage and Corrosion Resistant Adjusting Screws. Serviceable in line. Replaceable Seat Module. Designed to reduce incoming water pressure to a sensible level to protect plumbing system components and reduce water consumption. Adjustable range 10 to 35 lbs. The residual pressure valve (RPV) technology was invented by NERIKI more than 25 years ago, with worldwide sales in excess of 8.0 million pieces. Iwatani has exclusively sold the NERIKI RPV to the North and South American markets for industrial and specialty gas applications successfully and can help tailor a program for your company, whether large or small.
