ZURN Z7300-SS-MT is a recessed mounted mechanical shower mixer with pressure balancing cartridge and solid control lever. Pressure balancing cartridge delivers nearly constant water temperature despite pressure fluctuations in either the hot or cold water supply lines giving anti-scald protection to the user. Mixer is operated by rotating from cold through to the hot position. The valve body is a four port valve with a bath outlet plug included for shower only applications. The valve inlets, shower, and bath outlet are all standard with F1/2” female thread connections. Pre-set maximum temperature limiter (is adjustable by the installer). Flow rate limited to 9L/min at 300kPa, 6L/min with shower head. Maximum pressure difference between hot and cold supplies should not exceed 35kPa. Outlet to shower head must be full diameter pipe to prevent back pressure. Supplied with F1/2" inlets and polished nickel chrome plated surface cover plate.
