|Model||Flow Capacity||Hot Water Outlet Connection Size|

Model Z358 is a thermostatic mixing valve (TMV) available in two flow capacities and suitable for installation at or near a point of use for tepid water supply to a single, combination or group of emergency fixtures in accordance with ANSI standard Z358.1-2009.
The unique constant cold-water flow feature allows inlet hot water supply to be set within a prescribed range, which limits the potential outlet temperature to a safe maximum. The valve also features a single temperature locking feature and a thermal shutdown feature that protects users from accidental scald risks in the case of an interruption to cold water supply.
