ラレルフイーダとを連通させた合流制御弁。 A pair of actuator ports are formed in the valve body, and a spool is slidably provided in the valve body, and when the spool is held at a neutral position, the tandem passage and the neutral passage communicate with each other, and the spool is moved to either side. When switched to the position, communication between the tandem passage and the neutral flow passage is cut off, while the parallel passage and the parallel feeder communicate with each other via the check poppet. In the merging control valve, the check poppet is held in a sleeve, and the check poppet is held in a sleeve, and the check poppet is held in a sleeve.
A merging control valve having an annular passage formed on the outer periphery of the sleeve and communicating the pumps of other circuit systems with the parallel feeder via the annular passage.
