Claims

[Scope of utility model registration request]

In a valve that opens and closes a valve port formed in the valve plate by relatively moving a pair of valve plates that are in sliding contact with each other, a narrow groove that does not communicate with the valve port when the valve port is fully closed is provided in one or both valves. A sliding valve plate for a valve, characterized in that a sliding valve plate is formed on the sliding surface of the plate.
