GENERAL DESCRIPTION:
Cast brass body, washerless 47 mm ceramic disc valve cartridge with volume and temperature control, back-to-back capability, integrated check valves, and hot limit safety stop. Pressure balancing cartridge maintains constant output temperature in response to changes in relative hot and cold supply pressure. One-half inch inlets and outlets (choice of universal, direct sweat, threaded, PEX or CPVC). Available with screwdriver stops. Rough-in plaster guard designed for use as thin-wall mounting adaptor. Valve body will accept a variety of decorative Bath/Shower trim kits.
PRODUCT FEATURES:
Cast Brass Valve Body: Durable - Quality that will last
a lifetime. Ideal material for prolonged contact with water.
Ceramic Disc Valve Cartridge: Assures a lifetime of drip-free performance. Allows easy control over both water
temperature and volume.
Pressure Balancing Valve Cartridge: Maintains constant output temperature in response to changes in relative hot and cold supply pressure. Diaphragm system with integrated check valves engineered to eliminate cross flow. Avoids failure due to mineral deposits - ideal for use in
hard water.
Back-to-Back Capability: Hot and cold can be
reversed quickly and easily.
Adjustable Hot Limit Safety Stop: Limits the amount of hot water allowed to mix with cold. Reduces the risk of
accidental scalding.
Exclusive Plaster Guard: Plaster guard is designed to protect valve during installation and serve as a mounting plate for thin-wall installations. Two-piece design allows
valve to be tested prior to trim installation.
Wide Rough-in Range: From 1-5/8" to 3-1/4".
