FIELD: pipeline fitting, namely used as electromagnetic valve whose drive is controlled by means of short-period electric pulse. ^ SUBSTANCE: electromagnetic valve includes housing, connected to armature shut-off member, electromagnet, stop, permanent magnet and sealing tube. Permanent magnet is arranged in turning formed in stop. Depth of said turning is equal to sum of permanent magnet thickness and value of armature stroke. Armature has step reciprocal to turning. Value of said step is equal to value of armature stroke. ^ EFFECT: lowered power of electromagnet at providing target pulling effort in working gap. ^ 3 cl, 4 dwg |
