Abstract
Embodiments of a normally open gas valve are disclosed herein. The normally open gas valve includes a valve plug that gradually or partially disengages from the valve seat such that the actuation power required to open the valve is substantially reduced. The force required to open or close the valve is also reduced through the use of an off-center lever arm that multiplies the force applied by the armature of the actuation means. In this way, a less expensive actuation means, e.g., a less expensive solenoid, is able to be used to actuate the normally open gas valve.
