ELS
Series Electric Rotary Valve Actuators
 Description/Overview
ELS Series Electric Actuators
produce up to 221 lb. in. of torque, utilize a spur gear system designed
for 2-way and 3-way ball valves (EL Series recommended for butterfly applications)
an dfeature a 50% duty rating and weatherproof housing.
ELS Series Actuator Options
include:
-
Two extra switches for control
of auxiliary circuits
-
Feedback potentiometers for
position indication
- MOD positioner
- ELS 25 Model
-
Low voltage DC motors for vehicular
applications
- Special paint
and labeling (minimum order quantities required)
Features
-
Housing - compact and
fully gasketed for weatherproof applications. Two part polyurethune
coating system passes 500 hour salt spray test (requirement for NEMA 4X).
-
Motor/Gearbox -
permanent split capacitor fan cooled motors after ball bearings and integrated
thermostatic overheat protection. Gearboxes are sealed and maintenance-free
with steel spur gear train and "double-D" universal output shaft.
- Cam Actuated Limit Switches
- simple to adjust, cover up to 270° of rotation, and
provide secondaary outputs to light position indicator lamps
in control panel.
