Robertshaw 710-501 Gas Valve

The Robertshaw 710-501 Millivolt Gas Valve is a reliable low-profile gas control designed specifically for space heating applications where space is at a premium. This non-regulated Robertshaw valve features a 1/2" NPT inlet and a 1/2" NPT outlet, delivering a capacity of 150,000 BTU. Engineered for millivolt replacement projects, it functions without external power by utilizing the millivoltage generated by a standing pilot thermopile. The 710-501 manual valve includes a three-position knob (Off-Pilot-On) and provides versatile multi-position mounting capabilities, allowing for installation in any direction except upside down. For contractors performing a Robertshaw 710-501 conversion or repair, this unit is compatible with natural gas systems and offers a reliable thermocouple safety shut-off mechanism. Its compact footprint makes it an ideal vent-free gas valve choice for floor furnaces and wall heaters requiring a 700 series gas control with high-flow performance and consistent pilot ignition gas valve operation under demanding residential or light commercial conditions.

• 150,000 BTU Capacity: High-flow throughput suitable for heavy-duty space heating applications.
• Millivolt Operation: Functions independently of line voltage, ensuring operation during power outages.
• Flexible Mounting: Can be installed in any position (except upside down) to accommodate tight mechanical footprints.
• Compact Design: Low-profile construction allows for integration into slim wall heaters and floor furnaces.
• Proven Reliability: Features a magnet-head safety system to prevent gas flow if the pilot flame is extinguished.

Is the Robertshaw 710-501 adjustable for high-altitude installations?
This is a non-regulated valve. Pressure regulation must be handled by the primary source or an external regulator if the appliance requires specific manifold pressure adjustments.

Can I use this gas valve with Liquid Propane (LP)?
The 710-501 is factory-set for Natural Gas. While the 710 series is versatile, always verify that the specific orifice and spring kit are rated for LP before attempting a field conversion.

What is the required millivolt output for this valve to stay open?
This millivolt gas control typically requires a minimum of 250mV to 750mV from a standard thermopile to ensure the internal operator remains engaged during operation.
