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".
