Robertshaw 700-501 Gas Valve

The Robertshaw 700-501 Gas Valve is a professional-grade millivolt combination gas valve designed for high-performance heating applications. This 1/2" millivolt gas valve features a non-regulated design, making it a versatile choice for technicians servicing systems where external pressure regulation is managed. Built as part of the 700-500 series, this unit integrates a manual gas cock, an automatic pilot safety valve, and a millivolt operator into a single compact housing. It is engineered with a 100,000 BTU capacity and is compatible with natural gas and LP gas systems. The valve includes NPT reducer bushings to ensure seamless Robertshaw 700-501 installation across various pipe sizes. With a thermopile-driven 750mV operating range, this valve ensures reliable pilot safety and main burner control without the need for external power, serving as a robust replacement for many OEM and competitive models.

• Universal Compatibility: Operates on a standard 250mV to 750mV range, making it compatible with most two-lead thermopiles.
• Flexible Mounting: The multi-positional design allows for installation in any orientation except upside down, accommodating tight cabinetry and manifold layouts.
• Durable Construction: Features an inlet filtered screen to protect the internal diaphragm and solenoid from debris and pipe scale.
• Field Adaptable: Includes two 1/2" NPT to 3/8" NPT reducer bushings to fit specific furnace or boiler gas lines.
• Standardized Terminals: Equipped with 1/4" and 3/16" NEMA quick-connect terminals to simplify wiring and prevent polarity errors during service calls.

Is the Robertshaw 700-501 regulated?
No, the 700-501 is a non-regulated model. If your application requires a specific manifold pressure, a separate pressure regulator must be utilized in the gas line.

Can I use this for propane applications?
Yes, this valve is suitable for LP gas as well as natural, manufactured, and mixed gases. Ensure your pilot orifice and external regulation are correctly sized for the specific fuel type.

What thermopile should I use with this valve?
This valve is designed for use with Robertshaw 1950 and 1951 series thermopiles, but it will work with any high-quality 750mV millivolt generator.
