モコン弁。 A push rod that is slid by the rotational deviation of the operating lever, and a control spool that is slid by the push rod via a pressure regulating spring and equipped with a supply port to a secondary pressure port and an oil drain port are arranged in the valve body. In the remote control valve for generating a secondary pressure corresponding to the rotational deviation, a piston is connected to the push rod and generates a force for reducing the operating force in opposition to the displacement force applied to the control spool by the secondary pressure. An operating force reduction rod with an attached actuator is attached to the control spool, and an actuator operating pressure introduction chamber is provided opposite to the operating force reduction rod, so that the actuator operating pressure is passed through the operating force reduction rod as an operation resistance force of the operating lever. A remote control valve with a load sensing mechanism.
