Maxon NI Series Non-Incendive Electromechanical Shutoff and Vent Valves

Maxon's electrically actuated valves shut off gas or oil lines in less than one second. A variety of body materials and connections provide reliable operation of the gas valve even for highly corrosive fuels and for oxygen. Normally open versions of these shut off valves are available for vent or process purge lines with Maxon's long-lasting metal-to-metal seating.

Maxon's electromechanical shut-off valves require only a power source from your burner management system or DCS. Maxon valve operating pressures and valve Cvs are among the highest available in the industry, so you can move more fuel in smaller size valves than competitive products.
