The valve piston (2) guided within the Valve seat sleeve (1) is pressed into the valve seat (3) by the hydraulic power and the spring force generated by the control pressure (X) on the control surface (5). Thus, the lines (A, B) are separated.
By switching the pilot valve (4), the control surface (5) is depressurised and the hydraulic power along the lines (A, B) can be used to lift the valve piston (2) o the valve seat (3), i.e. as soon as the hydraulic pressure is applied to the lines (A, B), the valve piston (2) moves into the opened position up to the mechanical end position. Thus, the lines (A, B) are connected. The ring-surface (6) of the valve piston (2) must be connected to the leakage line (Y) of the manifold.
