Upvc ball valve DN50, 100NM Electric Rotary Actuator with high
Rotary electric actuator is used for controlling 0°～360° rotation
of the valves and other similar products, such as butterfly valve,
ball valve, damper, flapper valves, cock valves, louver valve, etc.
It’s widely applied in petroleum, chemical, water treatment,
shipping, paper making, power plants, heating, light industry and
other industries. It is drived by 380V/220V/110V AC power. Control
signal is 4-20mA current signal or 0-10V DC voltage signal, which
enables the valve to move to the desired position, achieving its
automation. The maximum output torque is up to 6000N·m
Shell--The sheel is made of aluminium alloy, with anodic oxidation
treatment and polyester powder coating. It is strong
corrosion-resistang and enclosure IP67,NEMA 4 and 6, IP68 is
Motor--Fully enclosed squirrel-cage asynchronous motor, small,
large torque, and small inertia force, F-class insulation rating,
with termal protection to avoid damaging.
Manual Structure--The design of handle is
safe,reliable,labor-saving,small.If power failure, operted by
Indicator--Install indicator in the center shaft 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.
Sealing--Well sealing performance and enclosure IP67,IP68 is
Limit switch--Mechanical, electronic double limit. Mechanical limit
stopper are adjustable, safe and reliable; electronic limit switch
is controlled by cam, Set position accurately and conveniently, and
not affected by excessive handle.
Self=locking--Accurate worm and worm gear transfer large torque
efficiently, high efficiency, low noise (Max. 50dB), long life,
with self-locking, prevent inversion, as stable and reliable
transmission parts, no need to refuel.
Anti-offbolt--the bolt attached to the shell and be not off when
remove the shell.
Installation--The installation size meets international standard
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
1.Protection Grade IP8
a . Improve the upper and lower cover junction face to be
b . Photoscope
Not adopt chemical adhesive glue to avoid aging and flooding
because of working condition such as high temperature and high
After improving,AOX actuators meet the working condition
outdoor,,can be used in soaking with power in short time(Can be
used for long time if the oil seal of output axis is wearproof)
2 .The transfer part is more reliable
All the gear box is aluminium alloy material, to be prohibited from
The gear is stronger and more stable with 40 Cr steel material
through two times heat-treatment.
3 .The temperature rise of motor is lower
Enlarge the motor size,and under the same power, reduce the
capacitance, ,decrease the starting current and warming.
4 .The modification is more convenient
Improve the cam structure,integrate four-piece cams into two-piece,
separate with butterfly spring, tighten with anti-off bolt to keep
limit no matter under super high or low temperature. On the
contrary, other factorys who use M3 screw, cause some disadvantage
such as unaccurate location,strand slide,M3 spanner is easy to be
lost on-site and so on.
The regulating type is more steady and reliable
a . Enlarge the module size, more selection for compoment, to
increase the power
b . With weak power,be not subject to the module as the unstable of
c . Bare board is conducive to better heat elimination
d . One key positioning ,to avoid disorder of modification because
of too much button
e . Intelligent module fixed external
6 .Novel appearance
Unique and not stereotyped
7 .Fix the spanner on the shell,and will not be lost on-site
8 .More convenient for equipping with valve
a . The coupling is the same as pneumatic actuator, to unity the
standard and reduce the valve stock
b . Input the stem into the worm wheel directly,
to shorten the momentarm between the valve
and the output axis, stablize the output force.
