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.
Nameplate and abbreviations
Consult the nameplate of your valve. This lists the
maximum operating pressure, temperature limitations,
voltage requirements and service conditions of your
specific valve. Do not exceed nameplate ratings.
