FIELD: machine building.

SUBSTANCE: valve comprises body 11 with bore 13 and shutoff element 15. With valve closed, end face valve gate shutoff part 16 fits tightly seat 14. Gate 15 is arranged inside body 11 to displace therein driven by, first of all, electromagnet 23, into open position and, driven by permanent magnets, into closed position. Magnetic force or magnetic field force acting in closed gate position is lower than that acting on gate 15 and applied by valve drive. First permanent magnet 24 is arranged inside body 11 on support arranged therein. Second permanent magnet 25 is opposed to first one on gate 15 and features with identical direction of magnetic pole. Permanent magnets feature somewhat transverse sizes and are embedded in support on one side and, on opposite side, in gate 15 to make unidirectional poles of both magnets are opposed.
