　　(逆止阀)导热油、蒸汽止回阀为自动密封阀门，依靠介质力开、闭阀瓣，防止介质倒流,适用于蒸汽、冷热水、导热油、天然气等介质 retz(Check valve) Heat transfer oil and steam check valves are automatically sealedvalves that rely on medium force to open and close the valve disc to preventmedium backflow. They are suitable for media such as steam, hot and cold water,heat transfer oil, ammonia, natural gas, etc

　　进口蒸汽止回阀主要性能 Mainperformance

　　(逆止阀)进口导热油，蒸汽止回阀为自动密封阀门，依靠介质本身流动而自动开、闭阀瓣，有效防止介质倒流阀瓣设弹簧装置,阀门既可水平安装，也可垂直安装 RETZheat transfer oil and steam check valve are self sealing valves, whichautomatically open and close the valve disc depending on the flow of the mediumitself, effectively preventing the medium from flowing back. The valve disc isprovided with a spring device, and the valve can be installed horizontally orvertically
