Watts Series LF25AUB-Z3 Water Pressure Reducing Valves
Series LF25AUB-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 – 75psi (172 – 517 kPa). The LF25AUB-Z3 features Lead Free* construction to comply with Lead Free* installation requirements. 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.
Features:
• Standard construction includes Z3 sealed spring cage and stainless steel corrosion resistant adjusting & cage screws
• Union inlet connection
• Integral stainless steel strainer
• Replaceable seat module
• Lead Free* cast copper silicon alloy construction
• Serviceable in line
• Bypass feature controls thermal expansion pressure***
• High temperature resistant reinforced diaphragm for hot water
