Description
MAXON electro-mechanical valves are electrically
actuated fuel shut-off valves. The valves are designed for a
fast acting return to the at rest position upon removal of a
control voltage signal. Motorized automatic and manual
actuators are available depending on application needs. In
addition, normally-closed and normally-open options are
available. The normally-closed versions will shut off flow
when de-energized and pass flow when energized. The
normally-open versions will shut off flow when energized
and pass flow when de-energized. Electro-mechanical
valves are also offered in configurations that meet
hazardous locations.
