Unique. Strong. Efficient.
The patented Hansen Sealed Motor Valve is ideal for applications where external leakage is intolerable. The valve is suitable for use with a variety of fluids, including those that are incompatible with copper, such as ammonia,
because the copper windings of the motor stator are isolated from the fluid in the valve. Typical uses include slow opening solenoid valve, temperature controlled evaporator regulator, liquid injection to screw compressors, pressure control, liquid level control of pump accumulators, high side receivers or low side flooded chillers, or as a gravity drain valve.
The full ported HMMV valve series is best suited for computer controlled operations using 4-20 mA signals. The HMMV is ideal for precise temperature and pressure control, hot gas defrost, and other applications where accurate process control is required.
The Sealed Motor Valve is available with an optional Power- Close feature, an integral capacitor storage to close the valve in the event of either 24 VAC power failure or 4-20mA control signal failure. Power-Close motors are installed on HMMVC, HMMRC, HMXVC and HMSVC.
