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.
