Abstract
A valve device includes: a housing 10, defining an upstream side passage 12a and a downstream side passage 13a through which a fluid passes and an operation chamber C and a valve seat surface 11d interposed between the upstream side passage and the downstream side passage; a valve body 20, being reciprocated in the operation chamber to be seated and disengaged with respect to the valve seat surface; and a driving unit U, having a shaft 40 linked with the valve body and driving the valve body. In the valve device, the upstream side passage 12a and the downstream side passage 13a are arranged on a same axis L, and the valve seat surface 11d is disposed to be inclined with respect to the axis L, with the axis L as the center.
