exposion proof linear electric actuator control globe valve for
A linear actuator opens and closes valves that can be operated via
linear force, the type sometimes called a "rising stem" valve.
These types of valves include globe valves, rising stem ball
valves, control valves and gate valves The two main types of linear
actuators are diaphragm and piston.
CHL series lineal electric actuator has the characteristics of
small volume , light weight, powerful function, integrated
intelligent setting and easy operation. The max stroke length is
1m, The max force is 250000N. Lineal actuator is widely used in
valve on/off and debug which is lineal motion
1. Housing - housing is a rigid aluminum, anodized and polyester
powder coating, corrosion resistance, protection class IP67, NEMA4
and 6, and have IP68 and explosion-proof available.
2. Motors - totally enclosed squirrel-cage motor, small size, large
torque, small inertia force, insulation class F, built-in thermal
protection switch to prevent damage to the motor.
3. Manual configuration - hand wheel design ensures safe, reliable,
labor-saving, small volume. When not energized, pulled clutch lever
can be manually operated. When energized, the clutch is
4. Indicator - indicator is mounted on the center axis, the valve
position can be observed. Lens design using convex mirror, not
water, more convenient to observe.
5. Dryer - used to control the temperature, to prevent the
temperature and weather changes cause moisture condensation inside
the actuator, the internal electrical components remain dry.
6. Position switch - mechanical, electronic double limit.
Mechanical limit screw is adjustable, safe and reliable; Electron
limit switch is controlled by a cam mechanism, a simple adjustment
mechanism to accurately and easily set position, and from the hand
wheel excessive impact.
7. Torque switch - Provides overload protection to prevent damage
to the motor.
8. Self-locking - Precision double worm gear can efficiently
transfer large torque, high efficiency, low noise (max 50 db),
long-life self-locking function to prevent the inversion,
transmission part is stable and reliable part of the stable and
reliable, no need to refuel.
9. Anti-separation bolt - When removing the shell, bolts attached
to the case, will not fall off.
10. Installation - bottom mounting dimensions conform to ISO5211
international standard, the drive sleeve can be removed for
processing as needed, adaptability. Can be mounted vertically, it
can also be installed horizontally.
11. Line - control line to meet the requirements of single-phase or
three-phase power supply standard, reasonably compact line layout,
wiring terminals can effectively satisfy a variety of additional
12. Worm - using concave wheel design surface in contact with the
worm, transmission torque, balanced and wear and long life.
13. PCU board - compact structure, the PCU board built into the
