Abstract:
To provide a gate valve enabling an operator to easily recognize the number of revolutions of a valve stem.SOLUTION: A gate valve 1 includes a valve stem 2 to which a valve element 3 is mounted via a screw mechanism 4, and a housing 10 supporting the valve stem 2. The gate valve 1 further includes ball plungers 11, 12 held by the housing 10. In the outer periphery of the valve stem 2, latching recessed portions 37(1)-37(4) are provided to which balls 11a, 12a of the ball plungers 11, 12 can be latched. Each time the ball plungers 11, 12 are latched to the latching recessed portions 37(1)-37(4), an operator for the gate valve 1 can get click feelings due to latching. Thus, the operator can recognize the number of revolutions of the valve stem 2 at which the valve stem 2 is rotated, from the frequency of the click feelings.SELECTED DRAWING: Figure 5
