An electromagnetically controlled valve, wherein the closure-member is connected with the movable core of the controlling electromagnet in a simple and smooth manner by means of a coupling the members of which are rigid respectively with the core and with the closure-member, one of said members housing with a clearance the other member and defining with the latter a space inside which an O-ring is held with an axial clearance. Said O-ring fitted in an annular groove extending outwardly of the housing transmits the motion of the core to the closure-member so as to raise it off its seat.
