1500NM~6000NM Large Torque Electric Actuator With Gear Box Ex-Prof

1500NM~6000NM with gear box explosion-proof CE standard electric actuator

Summary:

Part-turn electric actuator is used for controlling 0°360° rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valve, cock valve etc. It widely applies to petroleum, chemical, water treatment, shipping, paper making, power plant, heating, light industry and other industries. Drived by 380V/220V/110VAC power or 24V/110VDC power, inputs 4-20mA or 0-10VDC control signal, moves valve to the right position, and achieves to automatic control, maximum output torque is 6000N·M.

Performance Feature

Shell--The shell is made of aluminum alloy, with anodic oxidation treatment and polyester powder coating. It is strong corrosion-resistant and enclosure IP67,NEMA 4 and 6, IP68 and explosion-proof is optional.

Motor--Asynchronous motor, small, large torque, and small inertia force, F-class insulation rating, with thermal protection to avoid damaging.

Manual Structure--The design of handwheel is safe, reliable, labor-saving, small. Declutch to operate by handwheel if without power, and reset automatically when power on.

Indicator-- Installs indicator in the center axis and adopts convex mirror design, no cumulate water, more convenient to observe.

Space heater-- It is used for controlling temperature to avoid condensing internal of housing and keep dry.

Limit switch-- Mechanical, electronic double limit. Mechanical limit stopper is adjustable, safe and reliable; electronic limit switch is controlled by cam. Set position accurately and conveniently, and not affected by excessive handle.

Torque Switch-- (Except CHQ-005/008/010) Providing overload protection to avoid the damage of valve and electric actuator when jammed by cutting power automatically.

Self-locking--Accurate worm and worm gear transfer large torque efficiently , high efficiency, low noise (max. 50 dB), long life, with self-locking, prevent inversion, as stable and reliable transmission parts, no need to refuel.

Anti-off bolt—The bolt attaches to the shell and be not off when remove the shell.

Installation-- The installation size meets international standard ISO5211 / DIN3337.

Circuit--Controlling circuit meets the single-phase or three-phase power supply standard, circuit layout is reasonable and compact, terminals meet various of additional functional requirements effectively.

The display of valve position—During the opening or closing movement of actuator, the change of valve position on LCD is displayed with large numbers.

Adjust the phase sequence automatically—Intelligent actuator check and test the phase sequence for 3 phase power supply automatically, users no need to consider about the phase sequence.
