Robertshaw 700-881 Gas Valve

The Robertshaw 700-881 Gas Valve is a professional-grade bleed gas diaphragm valve engineered specifically for high-demand commercial cooking applications. Operating as a millivolt gas valve compatible with thermopile systems, this unit features a 100,000 BTU capacity and standard 1/2" NPT inlet and outlet ports. Designed for precise fuel management, it is the direct replacement for 7000AMSGO and 7000AMSGOR-LP models. This valve integrates an automatic pilot valve and a built-in pilot gas filter, ensuring clean operation for 4290 (GS) gas controls. Note that 700-800 series operators are not interchangeable with standard 700 series hydraulic or 24V bodies. If you are servicing commercial fryers or ovens requiring straight-line pressure regulation, this non-regulated thermopile valve provides the stable gas flow necessary for consistent thermal output without the need for constant field adjustments.

Technical Specifications and Benefits

• High-Capacity Throughput: Rated for 100,000 BTU to support heavy-duty commercial kitchen equipment.
• Universal Installation: Features 1/2" NPT threading for standard pipe fitment in domestic and commercial gas lines.
• Bleed Gas Technology: Utilizes a specialized bleed gas operator for smooth diaphragm actuation and stable pressure control.
• Contaminant Protection: Includes a built-in pilot gas filter and adjusting key to protect the pilot orifice from debris.
• Multi-Position Mounting: Engineered to maintain reliable gas regulation in various mounting orientations found in tight equipment chassis.

Common Questions

Is the Robertshaw 700-881 compatible with 24V systems?
No, this is a thermopile-actuated gas valve designed for millivolt circuits. It will not function with 24V AC transformers or standard 700 series electronic ignition bodies.

Can this valve be converted from Natural Gas to Liquid Propane?
This specific model is a non-regulated gas valve. While it serves as a direct replacement for 7000AMSGO (NG) and 7000AMSGOR-LP (LP) series controls, always verify orifice sizing and manifold pressure at the appliance level during installation.

What controls are typically used with this valve?
It is frequently paired with 4290 (GS) series gas controls in commercial cooking environments where precise bleed gas diaphragm operation is required for safety and performance.
