PURPOSE: A quantitative valve for feeding fluid at high pressure is provided to decrease the size of the constant flow valve by arranging a volumetric chamber and a spool in parallel, to prevent breakage of spool packing by modifying the structure, and to select the supply amount of fluid accurately by forming the multiple fluid discharge port. CONSTITUTION: A high-pressure valve for feeding the fixed amount of fluid is composed of a fluid cylinder(1) having a volumetric chamber body(1a) having a volumetric chamber(11) and a volumetric chamber cap(1b) fixing on the volumetric chamber body and mounting a discharge amount regulator(2) and a lift detecting unit, and charging or discharging fluid from the volumetric chamber by lifting up and down a piston(12) integrated with a rod in the inner volumetric chamber, and a spool housing(5) installed at the side of the fluid cylinder in parallel and composed of a spool(50) selectively supplying fluid to the upper and lower parts of the volumetric chamber and guiding the fixed quantity discharge of fluid.
