Electric Actuators
Features and Benefits
•
Spring return electric actuators are designed for load
requirements up to 2100 in. lb.
•
The actuator comes standard with two switches, an
to minimize condensation and NEMA 4x enclosure in
120/230
VAC or 24VDC supply voltage.
•
Spring return electric actuators come standard with ISO5211
mounting systems for easy mounting on complying valves.
•
Actuator is available in three different control modes:
-
on/off (2 position control)
-
floating control (Jog)
-
Proportional (modulating control) and depending
on the application it is offered in either clockwise or
counterclockwise rotation.
BES Series Heavy Duty Spring Return Electric Actuators
Part Number Key
These actuators are designed to provide fail-safe positioning
of valves upon loss of power. A mechanical spring set is used
to position the valve in either the OPEN or CLOSED position
without any external power source. A mechanical buffer is
utilized at the end of the spring stroke to reduce dynamic
effects. The actuator is available with or without a manual
over-ride.
