ELECTRIC CONTROL VALVE
OVERVIEW
XSL series electric actuator is one of the actuator products in the DDZ series of electric unit combination instruments. The actuator and the control valve body constitute an electric control valve, which is an actuator and regulating mechanism in the industrial process measurement and control system. It can be widely used in various industries such as petroleum, chemical industry, water treatment, shipbuilding, papermaking, power station, heating, building automation, light industry, etc. It uses 220V (110V, 380V) AC power supply and 24V DC power supply as the driving power supply, and 4-20mA current signal or 0-10V DC voltage signal as the control signal. It can move the valve to the desired position and realize its automatic control. The maximum output torque is 25000N.
PERFORMANCE FEATURES
A variety of working modes are available, flexible and convenient;
Control signal: current signal (4~20mA or other non-standard signals)
Voltage signal (0-10V or other non-standard signals)
Positive and negative action can be selected, and the split-range control mode can be easily realized.
Output signal: current signal (4~20mA or other non-standard signals)
Voltage signal (0-10V or other non-standard signals)
Communication interface: RS485;
Flow characteristics: linear, fast opening, slow opening, custom
Valve action direction: positive and negative action selection
Chinese and English LCD display: menu operation, human-computer interaction is more humanized; easier to use;
Stroke self-tuning: innovative mechanical design, simple and fast stroke position adjustment, input signal and stroke relationship adaptive tuning, to meet the needs of different stroke valves;
Self-diagnosis function: the actuator automatically records the working parameters during operation. When the actuator fails, the main control module will detect and alarm in time, the fault will be displayed on the LCD screen, and transmitted to the control center through the switch signal.
Easier operation: innovative structural design, non-invasive operation, easy to operate without opening the casing.
Remote control/local control button switch.
Handwheel priority mode, once ejected, automatically protects the actuator, manual operation is easier, and the handwheel is safe and reliable.
More reliable control circuit: The motor drive adopts contactless control, no sparks, and long life; wide power supply adaptation range, 380V power supply model phase adaptation, users do not need to worry about wrong phase connection; circuit module is fully digitally controlled, no mechanical potentiometer exists, users do not need to worry about mechanical vibration and transportation affecting product accuracy; using advanced anti-interference technology, even in harsh environments, it can calmly deal with it, and the new "watchdog" technology is far away from the trouble of "freeze";
Delay protection for actuator movement direction reversal, longer life of power transmission components; Lower working noise.
WORKING PRINCIPLE
The working principle of the XSL series intelligent linear turn electric actuator is shown in the figure. The single-chip microprocessor and peripheral chip form an intelligent control unit, which receives standard 4-20mA DC signals (or voltage signals), and sends them to the microprocessor after signal conditioning and A/D conversion. The microprocessor sends the processed data to the LCD to display the adjustment results. The control signal generated after the operation and processing drives the motor, drives the transmission screw after speed change, generates mechanical stroke, and feeds the data to the microprocessor for data processing after position detection to complete the action of the "signal and position" correspondence relationship.
In addition, the system also has a communication function, which can receive instructions from the host computer and perform remote digital control. Operations are performed on the intelligent controller panel, and the actuator can also be controlled locally through menus and buttons. This system also has fault alarms and independent analog 4-20mA position feedback outputs.

PACKAGING PROTECTION MEASURES
Packaging structure and materials
The packaging should be designed to be both strong and lightweight to withstand various pressures and impacts during transportation. The materials used should have good weather resistance, chemical resistance and wear resistance to adapt to different transportation environments.
Sealing and leak-proof
The packaging adopts reliable sealing technology, such as heat sealing, glue sealing or the use of sealing rings, to ensure the air tightness and liquid tightness of the packaging.
Easy to handle and identify
The size and weight of the packaging conform to ergonomic principles, ensuring safe and convenient handling for handlers. At the same time, the packaging clearly indicates the cargo information, such as name, weight, and destination, for quick identification and classification.
Special cargo identification
For special goods, such as flammable, explosive, toxic, corrosive or radioactive substances, the corresponding dangerous goods label must be affixed to the packaging.
