The present invention relates to a high pressure piston valve. The high pressure piston valve includes an inlet unit in which a fluid is drawn from one end; a first operation hole drawing pressure by being formed on the side and discharging the drawn pressure to the other end; a first body which the fluid passes through; a second body including a first groove, a plurality of second operation holes, and a drawing unit; and a piston including a piston unit, a second groove, a first balancing piston unit, a plurality of third operation holes, a plurality of fourth operation holes, and a second balancing piston unit. The first groove of the second body is connected to the other end of the first body and is formed on the other end along the outer edge. The second operation holes protrude by the first groove and penetrate the bottom surface of the first groove, an outer edge unit, and an inner wall to the outside. The fluid passes through and is drawn by the drawing unit. The piston unit of the piston is wedged in the second body and is inserted into the first groove. The first balancing piston unit is formed on the inner side of the second groove. The third operation holes penetrate askew from one end of the first balancing piston unit to the other end so that the pressure drawn to the inside is drawn out. The fourth operation holes penetrate from one side wall to the inside so that the pressure drawn to the inside is drawn out to the outside of the wall. The second balancing piston unit is formed on the other end of the fourth operation hole. The high pressure piston valve is characterized in that the piston ascends when the pressure is drawn to the third operation hole and descends when the pressure is drawn to the first operation hole. The present invention is miniaturized, but it can be used at the pressure of 0-100 ���� |
