Silent Check Valve

A silent check valve, also known as a silent or quiet check valve, is a specialized type of check valve designed to minimize the noise and water hammer associated with traditional check valves. This valve operates within a pipe or fluid system to control the flow of fluids and prevent backflow. Its primary components include a valve body, a disc or flap, and hinge mechanisms.
