Abstract
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.
