着したことを特徴とする電磁比例制御弁。 In an electromagnetic proportional control valve, the opening area of a fluid passage is continuously controlled to open and close at a spool according to the input current by moving a plunger using an electromagnetic force proportional to the input current and a biasing force of a spring. An electromagnetic proportional control valve characterized in that a spool is slidably supported by a sleeve, a circumferential groove is provided in the hole wall of a small diameter hole in a body into which the sleeve is fitted with clearance, and an O-ring is attached to the circumferential groove.
