Grey Multi Turn Actuators With 20NM - 2030NM Torque , Motor
Operated Valve Actuator
In many areas such as islands, plateaus, pastoral areas, desert
Gobi, and remote mountainous areas, the control of pipe network
valves is mostly powered by natural energy sources such as solar
energy and wind energy. However, a solar power supply system
consists of a solar photovoltaic cell module, a solar controller, a
battery (group), etc., and an inverter must be configured to invert
the direct current (DC24V) generated by the solar module into an
alternating current (AC220V) according to actual needs. The normal
use of the valve has the inconvenience of high cost and low
efficiency. In order to meet the demand for electric valves in
these special fields, our company designed and developed a
vector-controlled permanent magnet brushless DC motor based on the
AC power supply technology, and developed the DZ series DC power
supply intelligent non-invasive valve electric device. Powered by
the battery pack. This is an intelligent electric valve control
product integrating DC motor control technology, absolute coding
technology, programmable single-chip technology, infrared remote
control technology, liquid crystal display, magnetic control switch
and other recent automatic control technology and advanced
DZ series DC power supply intelligent non-invasive valve electric
device is mainly used for the valve for linear motion of the
opening and closing parts, such as gate valve, globe valve,
diaphragm valve, gate, etc., for opening, closing and adjusting the
valve. It is an indispensable driving device for remote control,
centralized control and automatic control of valves. It has the
features of full function, reliable performance, advanced control
system, small size, light weight and convenient use and
The product is tested by a number of performance tests, with stable
and reliable performance and convenient operation. At present, it
is the only valve electric actuator product in China that uses DC
1, manual operation
Direct drive handwheels (or larger models and geared handwheels
used on AKM) provide reliable emergency manual operation in the
event of a power failure. The padlock manual/automatic clutch
ensures safe operation even when the motor is running.
Note: Motor operation is always preferred unless the
manual/automatic handle is intentionally locked in the manual
position. Both the direct drive and the independent gear driven
handwheel have a free-range "hammering" effect.
2, non-intrusive settings
All actuator settings and diagnostics are performed through a
sealed indication window, eliminating the need to remove the cover
on site and expose the internal control mechanism.
3. Local control
Field control switches and padlock-type field/stop/remote selection
operate the internal magnetic reed switch, eliminating the need for
a through-shaft that seals against moisture.
4, position control
The Hall-effect magnetic pulse system accurately measures and
controls the travel of the actuator without the use of any gears
5, the terminal box
The individually sealed terminal box ensures the integrity of the
motorized seal even when the terminal box cover is opened for field
6, AKC / AKM electric and drive
The motor shaft and the worm are independent of each other for
quick replacement. The low inertia, high torque motor allows the
peak torque to be reached quickly after the motor is started, and
there is almost no overrun during non-excitation. The temperature
coil has a precise temperature sensor that is unaffected by the
ambient temperature and allows the motor to be in optimum heat
capacity. The motorized section includes a free-range "hammer"
device that helps to open and close the over-tightened valve. The
worm gear and the worm are individually immersed in the lubricating
oil to suit the maximum ambient temperature difference.
7, flexible drive connection
Cast iron, water sealed housing. A simple, detachable drive bushing
can be machined to the valve stem for connection to the valve.
Display of actuators
The AKC/AKM family includes a unique display developed specifically
for actuator displays. Its large screen allows users to easily see
valve position, torque and diagnostic faults from a distance. The
unique display system with background lighting system provides high
visibility under all lighting conditions.
ACKO recognizes that local and remote valve position instructions
are required at all times, even when the actuator power is off.
AKC/AKM has a built-in battery to maintain and update valve
position instructions when power is off. The power also supports
data recording when power is off.
By setting, adjusting and viewing the intrinsically safe AKC/AKM
infrared setter, users can easily enter the configuration of the
actuator through the display.
Diagnostic information on screen
The three display areas of LCD can clearly display the alarm
information of valves, control systems and actuators.
AKM setter can query all the states of the current actuator in the
status query menu, so it can analyze the control signal, valve and
actuator status and indicating status in real time and in groups.
