[Claims for Utility Model Registration] Supply port, first and second output ports, and first
, in a valve body having a second discharge port, by displacement in both directions about the neutral position, communicating a flow path between the supply port and one of the output ports and between the other of the output ports and the discharge port, respectively. The main valve includes a valve member, a pilot chamber at one end of the valve member, a feedback chamber communicating with a first output port at the other end of the valve member, and a pilot valve for supplying and discharging pilot fluid to and from the pilot chamber. In the pilot type valve, the pilot chamber is provided with a first set spring that biases the valve member toward the feedback chamber, and the feedback chamber has a locking portion that locks onto the valve body on the valve member side. A centering bush that can be displaced in the direction of displacement of the member, and a second set spring that presses the centering bush to a centering position where the locking portion locks onto the valve body are provided, and the biasing force of the second set spring is is larger than the biasing force of the first set spring, and with the valve member in contact with the centering bush at the centering position, the supply port and the second output port and the first output port and the first The pilot valve is configured to communicate the flow path between the discharge ports, and the pilot valve is driven by a proportional solenoid in which the suction force acting between the iron cores is proportional to the amount of energization to the solenoid. A pilot type electropneumatic proportional valve configured to output a fixed fluid pressure.
