Abstract
A gas valve having a cantilevered bi-metal arm subject to electrically energized heating regulates fluid flow between a fluid inlet and fluid outlet. A poppet is preloaded for seating with a valve seat and further includes a disc member to inhibit valve teasing. Projecting fingers from the arm operatively engage the disc member to provide consistent, repetitive movement between the poppet, arm, and valve seat so that the valve is uniformly opened and closed under various operating parameters.
