HOFFMAN SERIES 21H - TEMPERING VALVE Excess Pressure Pump Model 21LT provides the greatest

Model 21LT provides the greatest accuracy of temperature control

• Bearings never need lubrication

All programmable parameters are stored in non-volatile memory

so to change the rotation on the pumps simply loosen the bolt that holds the pump-end to the motor

• Maximum inlet water temperature 120°F (49°C)

HOFFMAN SERIES 21H - TEMPERING VALVE Excess Pressure Pump Model 21LT provides the greatestTempering Valves Series 21 Hoffman Specialty Tempering Valves are designed to control temperature in water mixing applications such asradiant floor heating, hot water 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.
