Abstract
A method of assembling an electromagnetic gas valve having a first body, a second body, a unit comprising a valve disc and stem assembly coupled to a moveable insulating structure having a projecting member, an electromagnet assembly comprising a magnet fixed within the second body and a coil wound on a moving part with a cavity adapted to receive the projecting member, the first body having a gas inlet, a gas outlet and a through hole disposed between the gas inlet and outlet. In one implementation the insulating structure is coupled to the electromagnetic assembly by introducing a fluid under pressure into the gas outlet or gas inlet to act upon the unit to cause the projecting member to move in a direction towards the inside of the second body and into the cavity of the moving part of the electromagnet assembly.
