FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electromagnetic valves. Electromagnetic valve for cryogenic gas comprises: inlet, outlet, passage connecting inlet with outlet, saddle connected with passage, ball interacting with saddle for isolation of passage, magnetic circuit. Magnetic circuit comprises coil generating magnetic flux in magnetic circuit, and magnetic plunger moving the ball from its seat to open and / or close passage. Magnetic plunger comprises two magnetic parts placed in magnetic flow, wherein two magnetic parts represent primary part and secondary part, movable one relative to the other and brought into action by magnetic flux generated by coil in magnetic circuit. Primary part includes a disk with holes, and the secondary part includes a rod crossing the disc with holes and moving the ball from its seat to control flow through the passage.
EFFECT: reduction of dynamic loads on the valve during its actuation and at the same time maintenance of its failure-free operation.
