It is available in concealed ver- Function sion "N9" (6) or in screwable version "N11" (7) (see page 2). The initial position of the valve (normally open "P" or normally The screwable manual override (7) must be screwed back closed "N") is determined by the position of the closing ele- into the initial position after actuation. ment (3) and the arrangement of the compression spring (2). Due to the structural design, the 2/2 directional poppet valves are always pressure-compensated in relation to the actuating forces. The main ports ① and ② can be loaded with an oper- ating pressure of 350 bar (see Technical Data, page 4).
