Claims

[Claims for Utility Model Registration] A valve in which a valve body in a valve case is opened and closed by application of pilot pressure to switch the flow path, wherein a piston chamber is provided in the valve case at an end position of the valve body. A piston movable in a direction perpendicular to the movement direction of the valve body is provided in the piston chamber, and a conversion mechanism is provided between the piston and the valve body to convert and transmit the movement of the piston to the valve body as movement in the opening/closing direction. A valve configured to apply the pilot pressure to the piston.
