MAIN FUNCTIONS

Explosion Proof

Based on your specific hazardous area classification and medium type (Group IIA/IIB/IIC gases or dusts), custom-engineer explosion-proof mini‑type electric flanged ball valve consists of an electric actuatorthat fully comply with international and domestic standards, including IECEx, ATEX, and GB 3836.

Colors

You can provide your own color code or choose special coatings for corrosion resistance, weather resistance, or high-temperature warning. Using advanced spraying technology and high-quality coatings, we ensure a durable, uniform finish. This gives your equipment a personalized look while maintaining long-term durability in industrial environments.

Protection grade

Based on your installation environment - outdoor rain, coastal salt spray, desert dust, or food/pharma workshops needing high-pressure washing. We provide sealing solutions from basic dust/water protection (IP65/IP67) to ultra-high protection (IP68/IP69K).

Low-temperature

For the specific operating conditions in extremely cold regions, we offer professional, deeply customized low-temperature environment services for Manual Worm‑gear PTFE‑Lined Butterfly Valve . By employing special low-temperature resistant materials, wide-temperature-range lubricants, and intelligent heat tracing systems, we ensure that the equipment can reliably start and operate accurately even in extremely low-temperature environments. We also comprehensively optimize the cold resistance of seals, electronic components, and display screens to effectively prevent problems such as lubrication freezing, sluggish displays, or start-up failures caused by low temperatures.

CONTROL MODE

External control All actuator signals, such as limit switch signals, torque switch signals, motor thermal protection and valve position, can be transmitted to the external control device for further processing. When designing the control logic architecture, it is necessary to fully consider the necessary protection mechanisms and minimize the delay time.

The contactor device used to control the operation of the motor is installed in the external control device and connected to the actuator via a cable.

When a local control operation interface is required, the local control operation interface should be installed near the actuator and integrated with the external control device.

Integrated control

When the actuator is powered on, the actuator with integrated control unit can be operated by the operating elements of the local control. The control unit is fully adapted to the actuator. The actuator can be set up on site without connecting to the DCS system. Only the transmission and exchange of operating commands and feedback signals are required between the control system and the actuator. The on-off control of the motor is completed instantly in the device.

Fieldbus

The use of bus cables can save a lot of space in the control cabinet, and it is more obvious that the traditional input and output signal line connection is outdated. The use of two-core cables simplifies the commissioning phase and greatly reduces the cost of cables in the long-distance field.

Another major advantage of fieldbus technology is the transmission of preventive maintenance and diagnostic information to the control room. Therefore, fieldbus technology integrates all fieldbus devices into the asset management system to support the safety protection measures of field device utilization. Actuators equipped with intelligent integrated control units can be applied to various common standard types of fieldbus systems in process automation.

Function Operation Instructions

Function	Instruction
Manual operations	The ML8824 series actuator can be operated manually using the supplied hexagon wrench and features a manual override function. For safety reasons, the actuator automatically cuts off the power supply to the motor when manual operations are performed. Note: The self-adaption process must be repeated after completing manual operations when the actuator is switched off! Rotate the hexagon wrench clockwise to shift the actuator connector downwards; rotate anticlockwise to shift the actuator connector upwards.
Enabling floating control	The ML8824 series actuator features a floating control function (see wiring diagram, page 5). When the S2-8 DIP switch on the PCB is set to ON (see Table of DIP Switch Settings, page 6), this indicates that floating control is enabled and the actuator will travel to the fully open or fully closed position without being controlled by the input signal (0/2–10VDC, 0/4–20mA). This ensures that manual operations can be completed safely.
Input	The analog input/feedback signal can be selected using the DIP switch (see Table of DIP
/feedback	Switch Settings). The default input/feedback signal is 0...10 Vdc. You can select 2–10VDC, 0–
signal	20mA and 4–20mA input/output signals using the DIP switches on the PCB.
Wiring	The actuator comes with a pre-assembled PG13.5 cable gland, with spaces reserved for PG13.5 and PG9 connectors. Note: To prevent the actuator from malfunctioning, connect it to a 24 V/AC power supply with a ground connection (see wiring diagram).
Self-adaption mode	Assemble the actuator and the valve and power the actuator with a 24 VAC/DC power supply. Automatic self-adaption: The actuator will automatically enter self-adaption mode when it is supplied with power. The yellow indicator light on the PCB will blink (1Hz) and the actuator will fully close (travel to the lowest position) and then fully open (travel to the highest position). The indicator light will stop blinking when the self-adaption process is complete. The actuator will then travel to the position designated by the control signal. Manual self-adaption: To enable self-adaption mode, press and hold the S1 button on the PCB for at least 5 seconds (see PCB Layout Diagram) until the indicator starts blinking (1Hz). The actuator will fully close (travel to the lowest position) and then fully open (travel to the highest position). The indicator light will stop blinking when the self-adaption process is complete. The actuator will then travel to the position designated by the control signal. Note: Travel calibration takes approximately 3 minutes for the 600 N actuator and approximately 4 minutes for the 1800 N actuator (when the default settings are enabled).
Actuator operating mode when input signal is interrupted	Use No. S2-9 DIP switch (see Table of DIP Switch Settings) to set actuator operation mode as the first step when input signal is interrupted. If the DIP switch is ON, actuator will keep the position when the input signal is interrupted. If the DIP switch is OFF, actuator will reset when the input signal is interrupted. Selecting actuator resetting requires the second step of signal interruption mode setting: setting the S2-6-digit DIP switch. No. S2-6 DIP switch is ON: when the controlling input signal is interrupted, if the input signal is a voltage signal, the actuator will automatically generate a 0(2) V/DC input signal; If the input signal is a current signal, the actuator will automatically generate a 0 (4) mA input signal. (factory default) No. S2-6 DIP is OFF: when the controlling input signal is interrupted, if the control signal is a voltage signal, the actuator will automatically generate a 10 V/DC input signal; if the input signal is a current signal, the actuator will automatically generate a 0 (4) mA input signal. Note: 1. The setting of DIP No. S2-9 takes priority over DIP No. S2-6. 2. The actuator keeps the position when input signal is interrupted is limited to input signal and feedback signal are 4-20mA.
