Robertshaw 700-057 Gas Valve

The Robertshaw 700-057 Gas Valve is a high-capacity, 1-inch NPT universal gas valve designed for heavy-duty residential and commercial applications, including boilers, central heating units, and large-scale furnaces. This 24VAC intermittent pilot gas valve is a versatile 700 Series Uni-Kit, providing technicians with a multi-functional control solution that replaces over 70 competitors' models. It features a factory-preset 4" WC natural gas pressure regulator and supports a high-flow capacity of 720,000 BTU (720 CFH). Engineering includes standard NEMA terminals and an inlet filtered screen to protect the internal diaphragm from debris. This HVAC gas valve replacement is designed for intermittent pilot systems but is field-adaptable for direct spark or hot surface ignition setups when using the included conversion components. Built for rugged environments, it maintains consistent performance across an ambient temperature range of -40°F to 175°F.

• Universal Compatibility: Replaces numerous OEM 1-inch gas valves in commercial boilers and high-BTU heating systems.
• High-Flow Capacity: Rated for 720,000 BTU (720 CFH) to meet the demands of large-scale equipment.
• Adaptable Ignition: Primarily designed for intermittent pilot systems, but easily converted to DSI or HSI applications.
• All-Position Mounting: Can be installed in any orientation (upright, 90°, or at an angle) to fit tight mechanical closets.
• Field Serviceable: Features accessible wiring connections and manual selectors for streamlined troubleshooting and adjustment.
