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. The check poppet is equipped with a piston that moves under the pressure action of the other actuator port, and the piston's moving force is applied to the check poppet to open the valve. In addition to providing a restriction valve that moves integrally with the
An operating check device that has an orifice that is always open and a communication hole that opens when a check poppet moves a predetermined stroke as the valve opens.
