About Maxitrol: A Global Leader in Gas Control Technology

For more than 75 years, Maxitrol has been synonymous with precision, reliability, and innovation in gas control technology. Founded in 1946 and headquartered in Southfield, Michigan, the company has grown into a recognized international manufacturer with production facilities in Southeast Michigan and Thale, Germany, and regional offices across Europe. This dual-continent presence allows Maxitrol to pool engineering resources and deliver products built for worldwide distribution.

One of the clearest measures of Maxitrol's commitment to innovation is its intellectual property portfolio — over 60 patents filed across 25 countries in just the past decade alone. That pace of invention reflects a company that is continuously refining its designs rather than resting on tradition. From residential heating equipment to demanding industrial gas systems, Maxitrol engineers products to perform consistently under real-world conditions.

What Maxitrol Makes

Maxitrol's core expertise spans electronic gas modulation systems, gas pressure regulators, combination gas control valves, gas safety devices, and gas filters. Their flagship 325 Series and RV Series regulators are trusted across residential, commercial, and industrial installations for their ability to deliver stable downstream pressure regardless of inlet fluctuations. Whether the application calls for a compact poppet-style regulator in a residential appliance or a high-capacity straight-thru-flow regulator in a commercial building, there is a Maxitrol product engineered for the job.

Beyond pressure regulation, Maxitrol's Selectra® brand represents the company's deep expertise in electronic gas modulation. The Selectra line includes HVAC control amplifiers that modulate gas flow in response to temperature signals, enabling furnaces, make-up air units, ovens, and paint spray booths to maintain precise discharge air temperatures. These amplifiers work in concert with Maxitrol's modulator-regulator valves to deliver instantaneous response and continuous pressure adjustment — a significant advantage over traditional motor-driven butterfly valves.

Rounding out the controls lineup, Maxitrol's Selectra Electronics division produces a broad family of temperature and pressure controls, including the Trakstat, Beta, and Pakstat series. These electronic controllers are engineered as cost-effective replacements for mechanical and pneumatic thermostats in OEM equipment, with flexible sensor options and narrow-deadband accuracy. For applications requiring straightforward setpoint control, Maxitrol also offers non-programmable and mechanical thermostats that provide dependable on/off control without the complexity of programmable logic.
