Torque 300 IN/LB – 1,600 IN/LB
The Engineered Solution
STANDARD FEATURES
Bettis TorqPlus has taken the lead in offering compact,
cost effective Spring Return Electric Actuator Packages.
Three models offer a variety of solutions when one needs
to protect a system upon loss of power. These actuators
have been designed for dampers, small
butterfly, ball and plug valves.
The Model EM-SR5 Series
is designed for use in
environments where automatic closing/opening
is required upon loss of
power, with a rugged
versatility that is hard
to beat.
When power is
available, the
device operates like
a normal quarter turn,
open/close or modulating
actuator. Under powered operation, the spring pack travels with
the movement of the actuator.
Under powered stopped
conditions, the actuator and
spring are held in position
via the electric mechanical
brake. Upon loss of power, the
spring is released and drives the
actuator to the predesignated
failsafe position. The failsafe
positioning can be provided for
either the CCW limit or to the
CW limit.
