Hoffman Specialty Type 21 Tempering Valve

Hoffman Specialty Tempering Valves are designed to control temperature in water mixing applications such as radiant floor heating and industrial processing. They can also be used to divert flow in cooling systems. Series 21 Valves can be used for residential, industrial, commercial or institutional applications.

Model 21 provides wide temperature adjustment range for hot and cold water mixing in applications other than domestic hot water.

Model 21H provides widest temperature adjustment range for radiant heating applications where accurate temperature control is less critical.

Model 21LT provides the greatest accuracy of temperature control.
