WTV series temperature responsive expansion valves(liquid injection) are usually installed suction side of compressorin refrigeration system to protect the refrigeration system from too high discharge gas or oil temperature.The capacities of WTVA,Website:://.fs-controls.com, WTVB series temperature responsive expansion valves(liquid injection) are large and usuallyused for large refrigeration system.WTVP series can work under no influence by suction pressure change. The liquid injection temperature need to be set in factory, and no adjusted in using.Liquid injection valve Operating principle:When the discharge gas or oil temperature in refrigeration system is too high, the valve will open. Liquid refrigerant will befed into the suction side and compression cavity after temperature drop yhrough the valve, and then cool the motor coil andthe mixture of refrigerant and oil, which makes the liquid refrigerant entering the evaporator in lower temperature. Technical dataMax.working pressure: 3MPaMax.testing pressure: 3.5MPaWTVP Series: Stationary type, Liquid injection, temperature can be customized.Connection inlet*outlet: 3/8*1/2 SAEStandard capillary length: 1 MDownload:WTV series Temperature responsive expansion valves
