The Robertshaw 700 series millivolt gas valves are wall thermostat actuated combination controls which provide installation flexibility from furnaces to swimming pool applications. The complete line of 700 - 500 mV gas valves offers a wide range of replacements from small capacity 3/8" pipe to high capacity 1" pipe up to 720000 BTU usage. These controls combine a manual gas cock, automatic pilot safety valve and a millivolt operator. The automatic pilot safety is separate from the gas cock and provides gas shutoff in case of pilot outage.

• Gas cock dial marking off-pilot-on
• Combination screw/spade terminal type
• Standard NEMA terminals
• Inlet filtered screen
• Various gas types - natural, manufactured, mixed, LP and LP/air mixtures
• 1/2" FPT side outlets with plugs
• Has coaxial thermopile connection
• Includes (1) 3/4 x 1/2" NPT reducer bushing

Robertshaw thermopiles are the industry leader for gas appliance applications. Their primary function is to ensure a standing pilot light is operative so that on a call for heat, the main burner gas will be properly ignited. Thermopiles are placed in gas applications to detect the existence of a flame for safety purposes by shutting off the potential gas flow to a burner. A thermopile is the assembly of many thermocouples to increase the millivolt output. Robertshaw thermopiles have two types of connections: coaxial and two-wire spade connectors. The 1951 thermopiles, also known as CP-2 (500 - 600 mV) are coaxial connectors. The 1950 and 1951 series thermopiles (pilot generators) are designed for use on self-powered gas control systems. They can be used to replace similar competitive devices.
