Product Details

Product Overview
The function of sanitary grade welded check valves is to only allow medium to flow in one direction and prevent flow in the opposite direction. Usually, this type of valve operates automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the valve seat is cut off by the fluid pressure and the self closing of the valve disc, which acts on the valve seat.

working principle
When the pressure below the valve stem exceeds the pressure above the valve stem and the spring force, the check valve opens. When the pressure on the valve stem is balanced, the valve will close. A higher reverse pressure will act on the valve stem to close it. Used in stainless steel pipeline systems to prevent fluid backflow.
