Carbon Steel Flanged Nozzle Check Valve

It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect. The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise. It can be installed on horizontal and vertical pipelines.

Carbon Steel Flanged Nozzle Check Valve

The opening and closing of the valve flap is determined by the pressure difference between the inlet end and the outlet end of the valve. When the pressure at the inlet end and the pressure of the outlet end expand the sum of the spring force, the valve flap is opened. The valve flap is always open as long as there is a pressure difference, but the opening degree is determined by the magnitude of the pressure difference. When the sum of the pressure of the outlet end and the spring force is greater than the pressure difference of the inlet end, the valve flap is closed and is always in the closed state. Because the opening and closing of the valve clack is a dynamic force balance system, the valve is balanced and free of noise, and the water hammer phenomenon is greatly reduced.
