A valve device includes a housing including a peripheral valve seat extended into a chamber, to separate the chamber into two separated spaces. A valve member includes an outer peripheral groove to receive a sealing ring for engaging with the peripheral valve seat of the housing, to make a seal between the valve member and the peripheral valve seat, and a casing is secured to the valve member. A spring member may bias the casing away from the peripheral valve seat, to force the sealing ring of the valve member against the peripheral valve seat, and to make a fluid tight seal between the valve member and the peripheral valve seat.
