ポート弁。[Claim for Utility Model Registration] A pressure acting chamber is defined by a diaphragm behind the diaphragm valve element that opens and closes the main valve seat between the inlet port and outlet port of the main valve, and the pressure acting chamber has an inlet orifice. In a diaphragm type pilot type two-port valve that allows pilot fluid flowing in from the valve to flow out through an outlet orifice that is opened and closed by a pilot valve, and opens and closes a main valve seat using fluid pressure in the pressure action chamber, the pressure action chamber side of the diaphragm The diaphragm receiver provided in the valve body is composed of a plurality of diaphragm receivers that are concentric and movable relative to each other in the stroke direction of the valve body, and the stroke of each diaphragm receiver is gradually decreased toward the outside. Diaphragm type pilot type 2
Port valve.
