Silent Check Valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, check valve, reverse flow valve, and back pressure valve. The Silent Check Valve manufacturer tells you that the check valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the reverse rotation of the pump and the driving motor, and discharge the medium in the container. Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Silent Check Valve manufacturers tell you that check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Silent Check Valve includes swing check valve and lift check valve.
Swing check valves have a hinge mechanism and a door-like disc that rests freely against the sloping seat surface. Silent Check Valve manufacturers tell you that in order to ensure that the valve disc can reach the proper position of the valve seat surface every time, the valve disc is designed in the hinge mechanism, so that the valve disc has enough swing space, and the valve disc is truly and comprehensively connected with the valve. seat contact. The Silent Check Valve manufacturer tells you that the disc can be made entirely of metal, or inlaid with leather, rubber, or synthetic overlays on the metal, depending on the performance requirements. In the fully open condition of the swing check valve, the fluid pressure is almost unimpeded, so the pressure drop across the valve is relatively small.
The disc of the lift check valve is seated on the sealing surface of the valve seat on the valve body. The manufacturer of Silent Check Valve tells you that this valve is like a globe valve except that the valve disc can rise and fall freely. Fluid pressure lifts the valve disc from the sealing surface of the valve seat. and cut off the flow. According to the conditions of use, the disc can be of all-metal structure, or it can be in the form of a rubber pad or rubber ring embedded on the disc holder. The Silent Check Valve manufacturer tells you that like the globe valve, the passage of fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the swing check valve The flow of the valve is rarely restricted. This type of valve should generally be installed horizontally in the pipeline.
