Abstract
A gas valve having a main valve closure member whose position is controlled both by a pivoting lever arrangement and a thermostatically controlled solenoid. The closure member is biased toward the lever by a spring between the closure member and the lever, and the lever is biased to position the closure member against a stationary valve seat. The lever is pivotable against its bias by a mechanical latch arrangement which forms part of a manual control, whereby when the lever is pivoted against its bias, the thermostatically controlled solenoid is permitted to engage the closure member, and, in the absence of demand from the thermostat, to move the closure member toward the valve seat against the bias of the spring between the closure member and lever.
