Exposion Proof Small Electric 12v dc Linear Actuator For Butterfly Valve

exposion proof linear electric actuator control globe valve for Butterfly valve

Summary:

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

Main features:

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 automatically reset.
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 functions.
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 chassis.
