FIELD: valving.
SUBSTANCE: valve comprises housing that receives two seats, shaped plunger with two trancated cones connected with the rod, and two lids provided with the slide bearing. The trancated cones of the plunger are mounted on the cylindrical rod one at a distance from the other that is equal to the distance between the sealing surfaces of the seats. The compensation conical ring is mounted on the intermediate sections of the rod . The outer diameter of the compensation ring is equal to the minimum diameter of the shape of the top trancated cone. The ring cross-section is the equilateral trapezium. The bottom base of the trapezium is equal to 1/3 of the length between the trancated cones. The top base of the trapezium is equal to ½ of the length of the bottom base.
EFFECT: enhanced reliability of control.
