Abstract
A normally closed solenoid operated valve assembly having a poppet movable between a valve normally closed position seating in and closing in orifice and a valve normally open position. A movable armature has a reduced section for engaging and pulling the poppet to the open position. A range spring tends to bias the poppet closed until the upstream force of fluid is sufficient to overcome the spring force. The spring force may be adjusted to vary to a predetermined value the upstream force of fluid. To open the valve, a solenoid is energized to move the armature thereby to move the poppet to the open position.
