Description
The Maxitrol M611 3/4 Modulator Valve is a precision gas control component engineered to deliver reliable, variable gas flow control in direct fired (negative pressure) HVAC burner applications. Ideal for systems that require rapid response to control signals, this modulating valve helps maintain steady burner performance by adjusting outlet pressure in response to electrical control input.
Key Features
- Precise Modulating Control – Designed so that an increase in control voltage corresponds to increased outlet pressure, giving fine tuned gas flow for efficient combustion and temperature regulation.
- 3/4″ NPT Size – Standard 3/4 inch threaded connections for easy integration with compatible gas lines in HVAC systems.
- Adjustable Low Fire Bypass – Built in low fire adjustable orifice allows accurate control during low load conditions.
- Upstream Regulator Requirement – Works with an upstream pressure regulator to ensure stable input pressure and proper modulation.
- Durable Construction – Designed for long term use in commercial and residential heating systems when installed by a licensed gas fitter.
