Robertshaw 700-442 Gas Valve

The Robertshaw 700-442 is a professional-grade 1" x 1" 24VAC combination gas valve engineered for high-capacity heating systems, supporting up to 720,000 BTU. This slow opening gas valve is designed to facilitate a soft ignition, reducing burner resonance and mechanical stress within the heat exchanger. It features a built-in pressure regulator factory-set at 3.5" WC for natural gas, though it includes a conversion kit for LP applications. This unit integrates a manual gas cock, an automatic pilot safety valve, and a 1/4" pilot outlet into a single compact housing. With its multi-positional mounting capability and straight-through side outlets, the 700-442 provides a versatile solution for standing pilot heating equipment requiring consistent manifold pressure and high-volume flow. Contractors depend on this model for its 7000ERHC-S7C factory configuration, ensuring broad compatibility across various commercial and heavy-duty residential boilers and furnaces.

• Slow-Opening Feature: Engineered for soft starts to prevent delayed ignition and system "booming."
• High BTU Capacity: Rated for systems up to 720,000 BTU/HR, suitable for larger light-commercial applications.
• NEMA Standard Terminals: Features combination screw/spade terminals for fast, secure electrical 24V wiring.
• Flexible Mounting: Multi-positional design allows for installation in any orientation except upside down.
• Safety Integration: Includes an automatic pilot safety magnet to ensure positive shutoff if the pilot flame is lost.

Is this valve compatible with LP (Propane) systems?
Yes, while factory-set for natural gas, this Uni-Kit model includes a regulator cover plate to convert the unit for LP gas use.

What is the benefit of a slow-opening valve versus a fast-opening one?
Slow-opening valves provide a metered initial gas flow during ignition, which is critical for preventing burner roll-out and excessive combustion noise in high-volume appliances.

Can the 700-442 be used with intermittent pilot systems?
The 700-442 is specifically designed for standing pilot applications. Always verify that your ignition control matches the valve's manual gas cock requirements before installation.
