Maxitrol 1" Modulating Gas Valve

These valves are designed to operate on indirect fired atmospheric burner applications. A pressure adjustment spring has been factory set to obtain an outlet pressure slightly above atmospheric pressure (0.1" w.c.) with the bypass closed and zero voltage being applied. The minimum flow rate is now adjusted through the bypass. They are suitable for Natural, Manufactured, Mixed, Liquefied Petroleum and Liquefied Petroleum Gas Air Mixtures. Note: This product should be installed by a licensed gas fitter.
