Maxon 125SMA11AA11BB21A0 Gas Valve 115V W/Vcs-Vos 1.25 Inch
The Maxon 125SMA11AA11BB21A0 are industrial gas valves designed to precisely control gas flow in a variety of applications, including HVAC systems, industrial burners, and furnaces. The maximum inlet pipe sizes of 1.25 and 1.5 inches are most likely indicated by the numbers 125 and 150, respectively. These valves include VCS-VOS control, which indicates compatibility with external voltage and current control systems for automated operation. They run on 115V AC power. They most likely work by controlling a passage's opening, which enables proportionate control of gas flow in response to signals received. The VCS component responds to signals from thermostats or other control systems to electronically control the valve opening. By ensuring that the gas flow properly meets the necessary heating demand, efficiency, and fuel consumption are maximized.
