In a spool operation valve consisting of a casing having a pump port, an actuator port, and a tank port, and a spool slidably provided within the casing, both ends of the casing are connected to the pump and both ends of the spool face. Each of the spools is provided with an oil chamber, and a bottomed hole that opens into each oil chamber is bored in the axial direction at both ends of the spool, and an oil passage that constantly communicates with the tank port is connected to each hole. A pair of rods are provided facing each other on the same axis as the axis of each hole for communicating and blocking communication between each hole and each oil chamber, and each rod is connected to each rod at each part of the casing. A spool operation characterized in that the spool is operated by following the movement of each rod by displacing each rod in the same direction via the connecting member. valve.
