Abstract
A straight-way valve comprising a valve body having regulating elements is mounted therein. The valve regulating elements include a plurality of discs, one of which is mounted for rotation and at least one of the other discs is statically mounted in valve body. The rotatable disc has a plurality of flow ports, which correspond with flow ports formed in the at least one static disc. The at least one static disc is arranged in face-to-face contact against the rotatable disc to form a fluid tight, mechanical seal. An actuating device is coupled to the rotatable disc and is mounted for rotation in said valve body. The actuating device includes means, which extend through the valve body for rotating the disc from an opened to a closed position.
