Abstract

PURPOSE: To provide sure blocking of a valve with an adequate seat face pressure to the valve body and seat and thus reduce the force required for the control, by pressing the valve seat to the valve body by virtue of fluid flowing through a passage at the time of blocking.
CONSTITUTION: When the valve body 15 is raised upward, the valve unit 15A is separated from the valve seat 13 to keep it open and then the fluid in the upstream passage 11a flows in the downstream passage 11b. The valve seat 13 held movable in the valve seat holding hole 12, when the valve unit 15A is open, moves to come in touch with the check step 12a. When the valve body 15 is pressed downward, the valve unit 15A slightly moves the seat 13 downward in the holding hole 12 while blocking the valve hole 13C of the valve seat 13, until it stops at a position where the flange 17 touches the stop 16. The seat face pressure between the valve unit 15A and the valve seat 13 automatically changes due to the pressure difference between the upstream and downstream passages 11a, 11b.
