Abstract
A manual valve provided with a valve body and a handle includes a lock mechanism to which a lock is attachable. The lock mechanism includes a movable member provided with first and second plate portions, and a support rod pivotally supporting the movable member. The movable member includes a mating hole engageable with only the handle placed in a fully-closed position. The movable member is guided along a guide hole through which the support rod is inserted to move between a locking position where the mating hole is engaged with the handle to lock the handle and an unlocking position where the mating hole is not engaged with the handle to allow rotation of the handle.
