WTV series temperature responsive expansion valves(liquid injection) are installed suction side of compressor in refrigeration system to protect the refrigeration system from too high discharge gas or oil temperature. Ths capacities of WTVA, WTVB series temperature reponsive expansion valves (liquid injection) are larger and usually used for large refrigeration system.
Operation principle
When the discharge gas or oi; Temperature in refrigeration system is too high, the valve will open. Liquid refrigerant will be fed into the suction side and compression cavity after temperature drop through the valve, and then cool the motor coil and the mixture of refrigerant and oil, which makes the liquid entering the evaporator in lower temperature.
