Abstract
Provided is a valve with which a seal member is not damaged when pressure accumulated near the seal member is released. This valve includes a valve box having a valve chamber, a valve seat provided in the valve chamber and having a seat surface, a stem including, at a tip end thereof, a valve element configured to abut against and move away from the seat surface due to an operation of an actuator, a seal space provided with a seal member configured to prevent a fluid from leaking, a seal opening space formed outside the seal space, and a seal pressing member configured to press and fix the seal member to a valve chamber side. The valve box is formed with a leak hole through which the seal space and the outside of the valve box communicate.
