A solenoid gas valve having a solenoid assembly and inlet and outlet fittings is installed inside a tube. The opening and closing of the valve is operated by the pressure difference with an aid of the magnetic field. A compression spring is attached to the support cylindrical body and held against the inlet end fitting while a moving solenoid assembly is located inside the support cylindrical body. The moving solenoid assembly that consists of a stop, a flange, a sleeve and an electrical coil, is held by a second compression spring that is attached to the inside of the support cylindrical body. A small moving magnetic rod, slides inside the sleeve of the solenoid assembly. Acted by a third compression spring, the magnetic rod seals the gas outlet through the bleed orifice on the flange of the solenoid assembly.
Électrovanne à gaz installée à l'intérieur d'un tube et dotée d'un ensemble solénoïde et de raccords d'entrée et de sortie. La vanne s'ouvre et se ferme en fonction de la différence de pression et à l'aide d'un champ magnétique. Un ressort de compression fixé au corps cylindrique de support est retenu contre le raccord d'extrémité d'entrée tandis qu'un ensemble solénoïde mobile se trouve à l'intérieur du corps cylindrique de support. L'ensemble solénoïde mobile est constitué d'une butée, d'une bride, d'un manchon et d'une bobine électrique, et est retenu par un second ressort de compression fixé à l'intérieur du corps cylindrique de support. Une petite tige magnétique mobile coulisse à l'intérieur du manchon de l'ensemble solénoïde. Un troisième ressort de compression agit sur la tige magnétique afin de fermer hermétiquement la sortie de gaz par l'orifice de prélèvement de la bride de l'ensemble solénoïde.
