<p>A hydraulic valve device has a valve housing (10) in which an activating piston (16) is guided in a movable manner. The activating piston (16) is actuatable by an actuating device (18) and activates a pilot valve (20) to connect a fluid port (T) in the valve housing (10) to a fluid chamber (22) of a shut-off piston (24). The shut-off piston (24) activates at least one fluid-conducting connecting line (1, 2) of the valve device and has a fluid conducting control line (26) opening from the connecting line (1, 2) into the fluid chamber (22) of the shut-off piston (24).</p> |
