Robertshaw 700-064 Gas Valve

The Robertshaw 700-064 Gas Valve is a universal 2-stage gas valve engineered for high-capacity 24V commercial and residential heating systems. Delivering a significant 720,000 BTU capacity, this 1" NPT gas valve is a versatile solution for applications ranging from large central furnaces to boilers. It is factory-set for natural gas with pressure regulation at 1.3" WC for low-fire and 3.5" WC for high-fire stages. For specialized installations, this unit supports intermittent pilot, direct spark, and hot surface ignition systems. The compact chassis features a manual gas cock, inlet/outlet screens, and a pilot gas filter to protect internal components. Designed for flexibility, it includes 1/4" quick-connect terminals and can be mounted in any position except upside down. The integrated slow opening gas valve feature ensures soft ignition, though it can be field-removed if the application requires a faster response. With its wide ambient temperature range of -40°F to 175°F, this 700 series Robertshaw valve provides reliable performance in demanding mechanical rooms.

• High-Capacity Performance: Rated for up to 720,000 BTU to handle heavy-duty commercial heating loads.
• Two-Stage Control: Enables precise 2-stage 24V AC operation, improving system efficiency and cycle modulation.
• Universal Compatibility: Fits 1 inch NPT piping and includes reducer bushings for simplified retrofit across various equipment brands.
• Enhanced Ignition: Features a slow-opening gas valve design for smooth, quiet lighting and reduced stress on combustion components.
• Reliable Safety: Includes a slotted automatic pilot safety magnet and a built-in pilot gas filter to prevent debris-related failures.

Can the Robertshaw 700-064 be converted for LP use?
Yes, while factory-set for natural gas, this Robertshaw 700-064 is a convertible gas valve. For LP applications, the regulator must be field-adjusted to 2.8" WC low-fire and 11.0" WC high-fire using the proper conversion kit and ensuring orifice changes are performed.

What are the electrical requirements for this 2-stage valve?
The valve operates on a 24V AC 50/60 Hz power supply. It draws approximately 0.2 Amps during low-fire operations and 0.4 Amps when the high-fire stage is energized.

Is this valve compatible with standing pilot systems?
The 700-064 is primarily utilized in intermittent pilot and electronic ignition setups; however, the 700 series universal gas valve platform is designed for broad application across different ignition types when properly configured with the included Uni-Kit components.
