Electric actuators are electrically
driven rotary motors that are directly
coupled to either ACV or FCV valves.
The position of the choke can be controlled
by either digital pulse duration or analog
signals transmitted from a remote location.
The electric motor and all electric controls,
if required, are enclosed in the housing
which can be supplied to NEMA standards
for hazardous locations for Class 1,
Division 1, Group D areas.
The actuator and valve assembly
is a compact package that offers precise
control of flow through the valve. Rotary
stem positioning is accurate to at least
±0.5% of full travel. A hand wheel for
manual setting is also available. The
power supply specified can be 110 VAC,
220 VAC, 12 VDC, or 24 VDC.
FCV valve (left) and ACV valve (right) are shown
with electric actuators.
