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. One actuator port communicates with the passage, and the other actuator port communicates with the tank passage, and a sleeve is installed inside the valve body, and a port member is screwed to the outside of the sleeve. In an operator check device, a check poppet is provided to allow free flow from the port to the cylinder, and the check poppet is opened by a pressing body that moves under the action of pressure on the other actuator port side. An operation check device in which a port sleeve is integrated with a port member, and its attachment/detachment operation area is open to the mounting surface of the valve body.
