Abstract
A double disk wedge valve the valve disk of which is movable by an actuating rod and is provided with a pipe bridge which includes two sealing rings connected by way of a compensator, said sealing rings in the open position of the valve being urged by elastic bias against the sealing seats of the valve housing, wherein said compensator comprises an inner pipe section and an outer pipe section extending in coaxial relationship therewith. The outer pipe section is fixedly joined, especially welded, to both sealing rings. Also, it has a circumferentially extending indentation. The inner pipe section is fixedly joined to only one of said two sealing rings while it is axially movable relative to the other one. Within the valve housing a gas pressure can be set which is higher than the pressure in the valve passageway in the open position of the valve.
