3/2 Wege-Sitzventil DN6 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 amaintained-contact function

Function of 3/2-way valve

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

The 3/2-way valve is provided with a „negative overlap“. During the changeover process, connections P, A and T are briefl y connected with each other. The changeover occurs so fast that the hydraulic effects are negligible. By design, a 3/2-way valve always requires the connection of a T-connector; only then a proper switching function can be ensured.

Depending on the design of the valve insert a valve with the basic position „A→T NO“ (lines A and T are connected) or „P→A NO“ (lines P and A are connected) is provided.
