Features:
▶ For threaded connection(screw-in threaded)
▶ Leakage-free blocking in one direction
▶ Various cracking pressure, optional
Application:
For industrial applications: The type S check valve is mainly used at the outlet of the pump as a back pressure valve and bypass valve.
The type S check valve has 7 sizes from size6 to size 30. It has the task of, preferably closing a flow leak free in one direction and to permit free flow in the opposite direction. The stroke of the poppet, which is guided on its outside diameter, is limited by a mechanical stop. The built-in compression spring supports the closing movement. Furthermore the compression spring holds the poppet in the closed position even when there is no flow through the valve.
