Silent Check Valve

The semi olive shaped valve body flow channel and gyro shaped valve core design of the silent check valve can effectively reduce and absorb the noise such as pressure wave roar caused by the valve disc and medium flow resistance during use, and also prevent medium backflow. When the direction of medium flow is reversed, the valve disc begins to close under the pressure of the backflow medium and the action of the spring. The spring can help the valve disc tightly adhere to the valve seat, thereby preventing medium backflow. The applicable scenarios of silent check valves are mainly used in various situations that require the prevention of medium backflow, such as water supply and drainage systems, pump and motor protection, and auxiliary systems that require the prevention of medium backflow. The main feature of the design of the silent check valve produced by Shanghai Meiyanyi Pump Valve is to consider reducing the generation of noise, so it has been widely used in some situations that require a quiet environment.
