ロット操作切換弁。(1) A solenoid valve is connected to the operating valve, and according to the operation of the solenoid valve, pilot pressure is applied to the main spool end of the operating valve, and this pilot pressure is supplied from an internal pilot passage communicating with the pump port. A pilot-operated switching valve capable of converting between an internal pilot type and an external pilot type supplied from an external pilot passage that does not communicate with the pump port, wherein a switching hole is formed to communicate the internal pilot passage and the external pilot passage, and , a common pilot passage communicating with the solenoid valve is formed in the switching hole, and one end of the switching hole is opened on the outer surface of the valve body of the operating valve, that is, on the side other than the joint surface on which the solenoid valve is connected. On the other hand, the switching hole is provided with a first plug that connects the internal pilot passage and the common pilot passage and blocks communication between the external pilot passage and the common pilot passage, or a first plug that connects the internal pilot passage and the common pilot passage and blocks communication between the external pilot passage and the common pilot passage. A second plug that communicates with the internal pilot passage and a common pilot passage that blocks communication between the internal pilot passage and the common pilot passage is detachable, and the heads of these first and second plugs protrude outward from the valve body. Pilot operated switching valve. （２）前記第１プラグの頭部形状と、第２プラグの頭部
