Natural Gas Regulators and Meters

Natural gas regulators play a crucial part in an HVAC residential, industrial or commercial system.

Maxitrol and Roots Regulators produce both LP and  natural gas regulators and meters and are two of the best gas regulator brands in the world today.

They reduce and regulate pressure to a normal level from the external natural gas lines suitable for appliance or system use. Without a natural gas regulator, the gas pressure in your pipes leading to the various appliances could change or reduce significantly.

With the all-important feature of an internal spring valve mechanism which adjusts and applies pressure against the opposing pressure in the gas line, natural gas regulators ensure that the right amount of fuel flows through your regulator to your HVAC system or appliance.

A flow or gas meter measures fuel gases to residential, industrial and commercial HVAC applications and systems.
