In a pilot type valve in which the main valve body is driven by fluid pressure, the pressure receiving surface of the piston has a non-circular shape in which the opening direction of the port is longer than the direction orthogonal to the pressure receiving surface, and the piston has a seal packing on the outer peripheral surface. The mounting part is provided with an engagement groove on the pressure receiving surface side of the mounting part for confirming the mounting position of the seal packing, and the seal packing mounted on the mounting part has an engagement protrusion that engages with the engagement groove. A pilot-shaped valve characterized by:
