Robertshaw 705-452 Operator

As a veteran HVACR technician, I know that field-converting manual gas valves to thermostat control requires precision-engineered components like the Robertshaw 705-452 Operator. This 120V operator is a critical component for pros working with the Robertshaw 700 series gas valve and 710 series models. It provides a reliable line voltage solution for natural gas applications, factory-set to a 3.5" WC pressure regulator to ensure consistent manifold pressure and optimal burner performance. This kit is specifically designed to replace older 700-450 and 700-460 series units, effectively upgrading manual systems to modern wall thermostat control without requiring a full valve body replacement.

Ruggedly built for high-demand environments, the 120 volt gas valve operator features a brown wiring block and standard NEMA terminals for straightforward electrical integration. It maintains stable operation across a wide ambient temperature range from -40°F upward, ensuring reliability in cold-start scenarios. When performing a Robertshaw 705-452 field conversion, always use the included gasket and mounting screws to prevent gas leaks and ensure a proper seal. This operator is compatible with HVAC natural gas controls in both residential and commercial heating equipment, offering the high-capacity flow management necessary for larger BTU demands.

• Field Conversion Ready: Designed specifically to adapt 700 and 710 Series manual valves to 120VAC thermostat control.
• High-Accuracy Regulation: Integrated regulator maintains 3.5 inches water column for steady natural gas delivery.
• Wide Compatibility: Serves as a direct replacement for various 705 series solenoid operators in commercial and residential heaters.
• Complete Installation Kit: Includes the operator, gasket, and necessary screws to ensure a secure, leak-free connection.
• Industrial Durability: Rated for severe ambient conditions, maintaining performance from -40°F to 175°F.

Common Questions & Technical Support

Can I use this operator on a 700-800 series bleed gas controller?
No. Do not use the 705-452 on 700-800 series (7000GO) controllers. It will not function properly and will create a hazardous condition. This is strictly for standard 700 and 710 series valve bodies.

Is this unit compatible with LP gas applications?
The 705-452 is factory-configured for natural gas at 3.5" WC. For LP applications, you would typically need a conversion kit or a specific LP-regulated operator to ensure safe combustion pressures.

Does this operator include the pressure regulator?
Yes, this specific model features a built-in 3.5" WC natural gas pressure regulator to manage manifold pressure directly from the operator assembly.
