する構成にしたオペレートチエツク装置。 A pair of actuator ports are formed in the valve body, and these actuator ports are connected to the cylinder, and either one of the actuator ports is connected to the pump depending on the switching direction of the spool built into the valve body. The other actuator port communicates with the tank passage, and a sleeve is installed inside the valve body, and the sleeve has a sleeve that allows the flow from one actuator port to the cylinder to be a free flow. In an operable check device, the check poppet is provided with a check poppet, and the check poppet is opened by the pressing force of a piston that moves under pressure action on the other actuator port side. The operating check device is constructed such that a variable orifice is formed in the valve, and the opening degree of the variable orifice is proportional to the opening degree of a check poppet.
