The sealing surface of j41b ammonia flange stop valve adopts Babbitt alloy, tetrafluoroethylene, nylon, etc. Low temperature resistant high-quality carbon steel or stainless steel is used as the valve body, with long service life. It is installed on the equipment or pipeline of the refrigeration system to connect and cut off the flow channel of the refrigerant. In the process of use, it can naturally achieve the chemical treatment performance in the environment of temperature difference changes.

Main uses of j41b flange stop valve for ammonia
