About this Product
A brand of Watts Water Technologies, Watts Regulator Company is an innovative manufacturer of water quality products for your plumbing needs. The Series LF223 High Capacity Water Pressure Reducing Valves (Part # 0298569) 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 (21 bar) and may be adjusted from 25 to 75psi (172 to 517 kPa). The standard setting is 50psi (345 kPa). Series LF223 features an enlarged diaphragm, spring cage and seat orifice for super capacity performance.
Why choose the Watts brand? For the simplicity and of course our low cost to you! All parts are quickly and easily serviceable without removing the valve from the line. The optional 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.
Additional Information :
• Bronze body construction
• Serviceable in line

Specifications: A Water Pressure Reducing Valve shall be installed on the water service pipe near its entrance to the building where supply main pressure exceeds 60psi (413 kPa) to reduce it to 50psi (345 kPa) or lower. Sill cocks and outside wall hydrants may be left on full main pressure at the option of the owner. Provision shall be made to permit the bypass flow of water around the valve back into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main. Pressure reducing valves with built-in bypass check valves and strainer will be acceptable.
