  • Various cracking pressure, optional

Industrial Applications

  • The check valve S20P is mainly used at the outlet of the pump as a back pressure valve and bypass valve.
  • This check valve S20P is one mounting subplate type of check valve S, which can be used in various high pressure industrial environment. 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.
