Abstract

PURPOSE: To prevent wear of sheets disposed on the sides of a valve body and a valve box, by providing a sheet moving mechanism which is capable of moving the sheets toward and away from each other while keeping the valve closed.
CONSTITUTION: In a valve 5, the second valve element 5b having a valve body sheet 8 is connected to the first valve element 5a having valve rods 6, 6 connected thereto by the intermediary of a hydraulic cylinder 11 including a compression spring 10 for normally urging the first valve element 5a toward the second valve element 5b. When the cylinder 11 is actuated by a control valve V, the valve body sheet 8 is brought into or out of engagement with a valve box sheet 9 by a sheet moving mechanism 12 while keeping the valve closed.
