Product Overview
The TOKYO KEIKI URG1-06-F-V-12-JA is a pilot-operated unloading relief valve engineered for precise pressure control and energy-efficient pump unloading in industrial hydraulic systems. Manufactured by TOKYO KEIKI (Tokyo Keiki Inc.), a recognized leader in fluid power and precision control technology, this valve belongs to the URG1 series of pressure control valves. The URG1-06-F-V-12-JA combines a relief valve function with an integral unloading capability, allowing the system pump to be de-pressurized (unloaded) when a predetermined pressure is reached, thereby reducing power consumption, minimizing heat generation, and extending pump service life. The valve operates on a balanced pilot-poppet and main-spool principle, delivering stable pressure regulation, low pressure override, and fast response to system pressure changes. With its compact subplate mounting design and robust construction, it is ideally suited for integration into high-cycle industrial hydraulic power units and machine circuits requiring dependable pressure limiting and unloading control.
