摘要：
A disc valve is linearly actuated to effect rotation of its sealing disc during opening and closing operations. Disc rotation is effected by creating unbalanced frictional forces between the sealing surfaces during valve operation. Rotation of the disc produces a lapping action that in the process medium renews and polishes the metal seating surfaces with each operation.
