What is an American Standard Flanged Swing Check Valve?

Shenchi factory's quality American Standard Flanged Swing Check Valve from Shenchi Standard operates on the principle of automatic opening and closing based on differential pressure. When the medium flows in the specified direction, the forward pressure overcomes the valve disc's own weight, pushing the valve disc to swing open around the hinge, allowing the medium to pass smoothly. Once the medium pressure drops or backflow occurs, the valve disc, under the combined action of its own weight and the reverse medium pressure, quickly swings back to close, tightly sealing the sealing surface, thus effectively preventing pipeline backflow. Corrosion-resistant materials such as WCB carbon steel, SUS304 (CF8), or SUS316L (CF3M) are available to ensure a tight seal.

Automatic opening and closing, precise backflow prevention

The Shenchi ASME standard flanged swing check valve operates automatically using the power of the medium itself, requiring no external drive. When the medium flows in the specified direction, the forward pressure pushes open the swing valve disc, allowing the medium to flow smoothly. When the forward pressure drops or backflow occurs, the valve disc automatically swings back to close under its own weight and the pressure of the reverse medium, cutting off the backflow path. This automatic opening and closing mechanism effectively prevents water hammer and backflow from damaging equipment such as pumps and compressors, making it an indispensable safety protection device in pipeline systems.
