Abstract

A fuel gas control valve capable of internationally acceptable operation, including a main valve operable in an on-off mode by an electromagnetic actuator that receives a signal from a conventional electric thermostat. A pilot valve is initially operated by a manual control, and is retained in the operating position by a power unit responsive to sensed presence of a pilot flame. A latching mechanism associated with the manual control interrelates with the main valve and overrides operation of the electromagnetic actuator in the event the pilot flame is extinguished for any reason. The valve also includes a mechanism that retains the manual control in pilot position until the pilot flame is established.
