与える事を特徴とする流体操作弁。 A fluid operated valve that has the function of opening and closing a flow path that creates a fluid flow, and has the function of closing the flow path by contact between a seat surface and a valve seat in contact with the seat surface. A structure that has a valve stem that presses the valve seat against the seat surface and applies a contact force, an elastic body is provided between the valve seat and the valve stem, and the valve stem directly separates the valve seat from the seat surface when the flow path is open, or It has a structure in which the valve seat extends from the valve stem through the elastic body, allowing fluid to flow in any direction, and when the flow path is closed, the valve seat extends from the valve stem through the elastic body. It has a structure in which the valve seat is pressed against the seat surface by the initial deformation force, and the flow path is closed by contacting the valve seat and the seat surface. When this flow path is closed, the effective fluid pressure in the direction of separating the valve seat from the seat surface is A fluid operated valve characterized in that when the effective fluid pressure exceeds the initial deformation force of the elastic body, the fluid pressure causes the valve seat to move away from the seat surface and provide an opening function to the flow path.
