DINKONDA GLOBAL Power Plants Special Adjustable/Switch Type M Series Angular Stroke Intelligent 0-90 ° Partial Rotation Variable Frequency Electric Actuator
Product Overview
The M series partially rotary variable frequency electric actuator
belongs to the intelligent electric drive device for angular
stroke, which outputs partial angular displacement of 0-90 ° and is
specially matched with butterfly valves, ball valves, plug valves
and other angular stroke valves. The product integrates a variable
frequency drive unit, intelligent controller, valve position
detection module, local operation panel, and manual emergency
mechanism. It can receive 4-20mA analog adjustment signals or
switch signals from DCS control system, drive valves to achieve
angle adjustment and switch cut-off, and rely on variable frequency
drive to achieve soft start stop and reduce impact load. It is
suitable for automatic control of industrial pipelines in
industries such as thermal power, chemical, oil and gas, and water
treatment.
Structural Composition
1. Intelligent local control unit: integrated LCD display screen
and local operation buttons, real-time display of valve position,
operating status, and fault codes; Support local/remote mode
switching, complete travel calibration and parameter configuration
on-site, and facilitate debugging.
2. Variable frequency drive motor assembly: Equipped with a
built-in variable frequency drive module, the motor adopts variable
frequency speed control, which can adjust the action speed, achieve
smooth start and stop, and reduce the impact of valves and
transmission mechanisms.
3. Partial rotary reduction transmission mechanism: a precision
gear reduction structure that converts the motor's rotational
motion into a 90 ° angular stroke output, with high transmission
efficiency, large load-bearing torque, and output torque
specifications covering multiple gears.
4. Manual emergency operating mechanism: Equipped with a
hand-operated handle, it can manually drive the actuator to open
and close the valve in case of power failure or control system
failure, for maintenance and emergency situations.
5. Valve position sensing feedback component: high-precision
angular displacement sensor real-time collects valve angle, outputs
DC4~20mA standard valve position feedback signal back to the
control system, forming a closed-loop regulation loop to ensure
positioning accuracy.
6. Multiple safety protection modules: built-in torque protection,
corner limit protection, motor overheating protection, overload
protection. When the torque exceeds the limit, the machine will
automatically stop, and the fully open and fully closed positions
will be automatically limited to protect the actuator and valve.
7. Explosion proof shell and independent wiring chamber:
high-strength die cast aluminum alloy shell, anti-corrosion spray
coating; Independent explosion-proof wiring chamber,
explosion-proof model can be applied to flammable and explosive
hazardous areas, equipped with cable sealing joints.
8. Bottom mounting bracket and output flange: Standardized angular
travel mounting base, output connection flange, can directly
connect butterfly valve and ball valve stem, compatible with
mainstream valve connection standards.
Core Features
1. Variable frequency soft start stop, low impact: Variable
frequency speed control, can freely set the opening and closing
speed, start and stop smoothly, eliminate mechanical impact, and
extend the service life of valves and actuators.
2. Angular stroke partial rotation output: standard 0-90 ° angular
output, suitable for butterfly valves, ball valves, plug valves and
other angular stroke valves, with a wide range of torque selection.
3. High precision intelligent adjustment: Built in servo control
algorithm, high positioning accuracy, customizable dead zone
control, smooth action, suitable for continuous adjustment of
process circuits.
4. Local and remote dual control mode: receive control room
adjustment/switch signals remotely; The on-site panel supports
on-site opening, closing, and stopping operations, and is equipped
with a handwheel for emergency operation.
5. Fault self diagnosis alarm: Real time monitoring of motor
overheating, torque overload, angle exceeding limit, signal
disconnection and other faults, with the LCD screen directly
displaying fault codes for quick positioning and troubleshooting.
6. Reliable protection performance: standard protection level IP65,
dustproof and waterproof, can be used in outdoor, humid, and dusty
industrial sites; Explosion proof version Exd Ⅱ BT4, suitable for
chemical explosion-proof areas.
7. Low operating noise: Variable frequency drive+precision gear
transmission, low operating vibration, low overall noise, meeting
the requirements of low-noise working conditions in the factory
area.
