2/2 Wege-Sitzventil DN3 PN700


  • Directly actuated directional seat valve controlling pressurised media.
  • The valve seat seals hermetically preventing internal leaks.
  • All parts are made of corrosion-resistant materials, and they are easily replaceable.
  • Valve design in a structural plate form.
  • On request, the valve can be equipped with other actuations than the electromagnet, e.g. hydraulic or pneumatic cylinder actuation, manual pushbutton operation.
  • In addition, the individual actuations can be supplemented with a maintained-contact function.

Function of 2/2-way valve

The force (1), generated by the actuation, acts through the lever (2), the tappet (3) on the ball (4) and presses it out of the valve seat (5). This is used to connect lines P and A, see Example. The ring (6) supports the fl ange seal from the inside. The volume fl ow is limited by the entire fl ow resistance.

Depending on the arrangement of the valve seat (5) and ball (4) the valve will have the basic position normally closed (NC) or normally open (NO).
