ABSTRACT:
The valve comprises a valve housing (39) and a valve member (28) which is tiltably arranged in the housing about a tilt axis (30) and which serves to close or free valve openings arranged on opposite sides of the tilt axis (30) in a flow passage leading from an inlet (46) to an outlet (48). The pressures which prevail in operation at the valve openings exert tilting moments on the valve member, and means (120, 138, 133; 122, 136, 133) arranged on both sides of the tilt axis are provided which exert compensating tilting moments on the valve member (28), with the said tilting moments and compensation tilting moments at least substantially cancelling one another in all positions of the valve member. An actuating device (12) is provided which controls the valve member and causes the valve member to execute a tilting movement. Both the valve openings (58) and also the compensation means (120, 138, 133; 122, 136, 133) are arranged so that they lie at least substantially in one plane, which brings considerable manufacturing and technical advantages.
