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 is connected to the tank passage, and one actuator port side is provided with a check poppet, and a piston chamber is formed on the valve body side. In an operable check device which is configured to include a piston that moves under the action of pressure on the other actuator port side, and to transmit the moving force of this piston to a check poppet to open the valve, there is a piston located outside the check poppet. , an auxiliary check poppet that allows only the supply flow to the cylinder, and a control orifice formed in parallel with the auxiliary check poppet.
