<p>An electrically operated valve assembly having a plastic body with a solenoid coil attached for moving an armature valve member for effecting flow from the valve inlet to outlet. In one embodiment the armature is a pilot valve sidably movable in a guide over which the solenoid is received. A spring loaded check valve in the guide releases over pressure within the valuing chamber. In another embodiment a spring loaded check valve in the body inlet passage releases over pressure to a bypass passage to the outlet. In a third embodiment a slug having a spring loaded poppet relief valve is welded over an opening in the inlet passage at generally right angles to the inlet fitting to provide direct relief of over pressure in the inlet.</p> |
