12V/24V Explosion-proof standard with hand wheel 200NM small
Samll 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.(CHQ series have got CE and explosion-proof certificate)
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
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
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.
