<p>A valve for controlling fluids is proposed, including at least one actuator unit (4) for actuating a valve member (3) which is axially displaceable in a bore (10) of a valve body (7) and which has at least one valve closing member (12), disposed in a valve chamber (18) and cooperating with at least a first valve seat (14), as well as a first piston (9) and a second piston (11). Between the pistons (9, 11), a hydraulic chamber (13) functioning as a hydraulic booster is disposed, which to compensate for leakage losses has a filling device, which comprises a pressure compensation conduit (24) that essentially transmits the pressure prevailing in the valve chamber (18) to the hydraulic chamber (13), making for a quasi-force-balanced valve (Drawing).</p> |
