The valves are equipped with swivel couplings and a combination of ball and spring that open when the pressure difference exceeds the spring force. The pressure difference required for the valve to open is called the opening pressure.

  Miniature check valves with floating disc

  Art.nr: N/A
  Miniature check valves prevent flow in one direction and allow flow in the opposite direction. Check valves can also be called one-way valves or non-return valves. Floating disk check valves have a disk that changes position inside the valve body depending on the direction of flow of the medium. In the forward direction, the medium can flow around the disk. In reverse flow, the disk is pressed against the valve seat and stops the flow.
