コン弁。[Scope of Claim for Utility Model Registration] (1) Pilot pressure is introduced from a pilot pressure hydraulic source by operating a pedal or lever, and the pilot pressure is applied to a pilot pressure receiving part of a hydraulic switching valve for controlling a hydraulic actuator. In the hydraulic remote control valve, a filter loading part is formed at the back of the hydraulic piping connection port of the hydraulic remote control valve, and a filter is attached to the filter loading part, so that the hydraulic oil introduced to the hydraulic remote control valve is A hydraulic remote control valve characterized in that the valve is configured to allow the water to pass through the filter. (2) A hydraulic remote control valve that introduces pilot pressure from a hydraulic pressure source by operating a pedal or lever, and causes the pilot pressure to act on the pilot pressure receiving part of a hydraulic switching valve for controlling a hydraulic actuator. A filter loading part is formed in the hydraulic piping connector connected to the port of the hydraulic remote control valve, a filter is attached to the filter loading part, and the hydraulic oil introduced to the hydraulic remote control valve is made to pass through the filter. A hydraulic remote control valve characterized by being configured as follows.
