For reliability, performance, flexibility and ease of installation and service in one compact control, Robertshaw's 24 volt combination gas valves are the answer. These valves feature a manual valve (gas cock), an automatic pilot safety valve, inlet/outlet screens, pilot outlet, pilot gas filter and pilot adjustment key. Regulated and nonregulated models are available. The automatic pilot safety valve is separate from the gas cock and provides gas shutoff in case of pilot outage. VALVES CAN BE MOUNTED IN ANY POSITION EXCEPT UPSIDE DOWN.
