This lead free HydroGuard® under the counter combination tempering valve for low flow control is designed for lavatory applications where the temperature of hot water must be controlled for safe, economic use. An advanced thermal actuator quickly senses and compensates for outlet temperature fluctuations induced by water temperature and pressure changes in the supply line. It features a rough chrome finish, 1/2 in NPT connections, corrosion resistant internal components, integral checks to prevent cross flow and inlet screens to filter out debris. The temperature adjustment stem is simple to adjust and has a locking nut to prevent unauthorized or accidental adjustment. Factory temperature is set at 105 deg F.
