Description
The Maxitrol M611‑1 modulating valve is a high‑precision, direct‑acting modulator designed for direct-fired burner systems. Unlike on/off valves, it provides continuous proportional control of gas flow in response to control signals — allowing stable, non‑oscillating temperature regulation without mechanical linkages or butterfly valves. It’s built to control combustion systems where maintaining fine gas flow modulation is essential, such as process heating, industrial ovens, makeup air systems, or direct-fired heating.
