These valves are most commonly used in commercial cooking applications in conjunction with the 4290 (GS) gas controls.
700-800 Series bleed gas diaphragm valves feature: automatic pilot valve, bleed gas operator, inlet and outlet screens, manual "gas cock" valve, pilot adjusting key, pilot gas filter and pressure regulator (optional by model).
Regulated models offer the additional feature of "straight line" pressure regulation allowing application of the 700 diaphragm gas valves to a wide range of capacity requirements without regulator readjustment. Minimum application for regulated models is 10% of capacity shown in the chart below, except high capacity models (1 x 1) which require a minimum of 200,000 Btu for proper regulation.
NOTE: The 700-800 Series Bleed Gas Valve Operators will not function properly if installed on a "normal" 700 Series Gas Valve body, i.e. hydraulic, 24 volt, etc.
