  • $260.00


The Robertshaw 700-424 is a high-capacity 24V diaphragm gas valve engineered for precision fuel control in demanding commercial and residential heating environments. This 2-stage gas valve is factory-calibrated for natural gas with a standard setting of 3.5" WC (Water Column), supporting a high-performance capacity of up to 300,000 BTU. Designed with a 3/4" FPT inlet and outlet, the 700-424 utilizes a 7000BGVER series body that provides secondary safety via an automatic pilot safety valve, which operates independently from the manual gas cock to ensure positive fuel shut-off during pilot flame failure. For the service technician, this Robertshaw 700 series unit offers multi-position mounting flexibility—functional in any orientation except upside down—facilitating straightforward gas valve replacement in tight furnace or boiler cabinets. The 3/4 inch 24V gas valve features standard NEMA 1/4" quick connect terminals and a 1/4" pilot outlet, making it compatible with various standing pilot and intermittent ignition systems. Constructed to withstand high-ambient conditions up to 175°F and a maximum inlet pressure of 14" WC (0.5 PSI), this commercial heater gas valve is a reliable choice for maintaining system efficiency and safety in HVACR applications.

Key Benefits for the Contractor:
  • High BTU Throughout: Rated for up to 300,000 BTU, making it suitable for larger commercial boilers and central heating manifolds.
  • Universal Conversion: Includes a regulator cover plate to easily adapt the natural gas valve for LP gas applications in the field.
  • Compact Safety: Integrated manual valve (gas cock), pilot gas filter, and pilot adjustment key streamline the gas control valve footprint.
  • Enhanced Durability: Equipped with an inlet filtered screen and RoHS-compliant materials to protect internal diaphragms from line debris.
  • Flexible Installation: Professional-grade diaphragm/solenoid design allows for multi-positional mounting tailored to specific equipment geometry.
Common Questions & Technical Support:

Is the Robertshaw 700-424 compatible with LP gas systems?
Yes, while factory-set for 3.5" WC natural gas, this natural gas to LP conversion is supported via the included regulator cover plate. Professionals should always verify pressure settings with a manometer after installation.

Does this specific model include an internal safety magnet?
No, the 700-424 is a no magnet gas valve. It relies on the 24V signal and the automatic pilot safety valve assembly. Ensure your control circuit does not require a notched magnet for an ECO (Energy Cut-Off) connection before ordering.

What are the electrical requirements for this valve?
The unit operates on a standard 24VAC @ 0.2 Amps (50/60 Hz) and is rated as an NEC Class 2 component, compatible with most 24-volt transformer-based ignition systems.
