パイロツト形弁。[Claims for Utility Model Registration] 1. A main valve having a plurality of ports opened substantially parallel to a plane including the axis of the main valve body, and a pilot valve, which acts on a piston sliding on a guide cylinder part. In a pilot type valve in which the main valve body is driven by pilot fluid pressure, the pressure receiving surface of the piston is made into a non-circular shape in which the opening direction of the port is longer than the direction perpendicular to this, and the piston is guided in the guide cylinder portion. A pilot-type valve characterized by being provided with a guide protrusion that guides a piston in cooperation with a surface. 2. The pilot type valve according to claim 1, wherein the piston is provided with a guide protrusion that guides the piston in cooperation with the guide cylinder. 3. A pilot-type valve characterized in that the valve box is provided with a guide protrusion that guides the piston in cooperation with the guide surface of the piston.
