The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: A valve device (1) includes: a lead-in flow path (21); lead-out flow paths (221, 222); valve bodies (131, 132) for switching communication/closure of the flow paths (21, 221, 222); valve seats (121, 122) on which the corresponding valve bodies (131, 132) are seated; a valve shaft (14) for integrally moving the valve bodies (131, 132); an actuator (15) for driving the valve shaft (14); a spring (37) for urging the valve shaft (14) in one direction; seal members (18, 19) provided on one side of a contact section between the valve bodies (131, 132) and the valve seats (121, 122); and valve seat protrusions (121a, 122a) provided on the other side thereof. In order to suppress the surface pressure at the contact section between the valve body (132) and the valve seat (122) where the seating load is higher than elsewhere, the seal member (19) and the valve seat protrusion (122a) are configured by selectively combining one of the multiple seal members having different trait characteristics and one of the multiple valve seat protrusions having different trait characteristics.
