One way brass valve refers to a valve whose opening and closing parts are circular valve discs and act by their own weight and medium pressure to block the backflow of medium.
The structure of lift check valve is similar to that of stop valve, only lacking the stem to drive the valve disc. The medium flows in from the inlet end (lower side) and out from the outlet end (upper side). When the inlet pressure is greater than the sum of the disc weight and its flow resistance, the valve is opened. On the contrary, when the medium flows back, the valve is closed. Swing check valve has an inclined disc that can rotate around the shaft. Its working principle is similar to that of lift check valve.
The two names are the same concept. Friends who need to buy one way brass valve, welcome to contact Jintian Group, one of the professional brass check valve suppliers.
