4. No cover opening debugging, parameter setting and configuration can be done through panel buttons or non-invasive infrared setters

5. Adopting automotive grade 32-bit ARM microprocessor, with fast processing speed, strong anti-interference ability, and high stability

6. Adopting a large screen OLED display, the Chinese and English human-machine interface is convenient and intuitive, with clear display, and can display position, pressure, diagnosis, and error indications.

7. Data logging function, with logs such as fault records, operation records, and alarm records, making it easy to query and trace

8. Complete protection functions can achieve phase loss protection, temperature protection, stall protection, locked rotor protection, pressure protection, intelligent jam protection, valve fault protection, etc

9. Multiple communication modes: analog, digital, PROFIBUS, MODBUS, etc

10. Single acting, double acting, switch type, and adjustable multiple series models are available for selection

11. Equipped with dual overpressure protection of overflow valve and pressure sensor, the pressure can be displayed digitally and intuitively

12. Quickly open or close the valve in case of a malfunction

13. In case of power failure, the valve can be opened, closed, or stopped to maintain its position

14. Zero leakage design, minimal maintenance, and high stability

15. Servo motor speed regulation, multi-level speed setting, stable operation, preventing water hammer impact

16. It can reach the protection level of IP68; Explosion proof grade EXdIIBT4/EXdIICT4 (optional)

Application

This series of products is divided into two major series: angular stroke and straight stroke, which can achieve single acting and double acting working modes. It can be matched with butterfly valves, ball valves, plug valves, dampers, gate valves, globe valves, etc. It is widely used in petroleum, chemical industry, metallurgy, electric power, light industry, ships, building materials, urban water treatment and many other fields to realize the regulation or cut-off control of valves.

The product has the characteristics of small size, simple structure, convenient installation, simple operation, large load capacity, high accuracy, high stability, long service life, and large load capacity.

Capable of remote, local control, and infrared remote control operation.

It has ESD Manual fire alarm activation function and manual on-off valve function.

Packing & Delivery

We use wooden boxes and pallets for packaging, and the valves will be wrapped in bubble film plastic bags to ensure maximum product safety. We support sea transportation, and products can also be shipped to any port you specify.
