VAD intelligent electric actuators hereinafter referred to as actuators can be matched with gate valves, regulating valves, globe valves, etc., and can be matched with butterfly valves, ball valves, baffles and other angular stroke valves (mechanisms) after being connected with the gearbox. High output torque, high precision, and various control methods. The good experience of years of application in its harsh and extreme environments proves that the quality of Hitewell's actuators is first rate.

Intelligent

The  DSP-based high-end large-scale integrated circuit, multi-core redundant control, powerful, with a watchdog, self-diagnosis, no need to restart.The intelligent algorithm FFT fast Fourier signal detection algorithm is adopted, the detection speed is within 1ms, and the whole detection process does not exceed 20ms, which can realize precise flexible control.

Simple

Setter debugging, no need to open the end cover, on-site debugging an average of 5 minutes, very convenient. Quick commissioning menu and factory default settings. The menu is displayed in Chinese and English menus.All are words, and parameters can be set even without a manual. No external power supply is required, and the internal battery can be used to complete the setting, especially in the new project on site.Valve commissioning when the force line is not in place, or valve commissioning becomes extremely simple and efficient when the valve plant power line is inconvenient.

Fiendly

High-definition LCD display with good visibility;

Chinese and English interface, real-time switchable;

The phrase display interface can be debugged without a professional manual;

The alarm interface is intuitive and can be read by non-professionals;

Intelligent maintenance

Intelligent Maintenance Systems (IMS) is the prediction and evaluation of the performance degradation process of the actuators, and predictive maintenance of the equipment.

Predict its performance degradation status in advance. Unlike traditional fault diagnosis, intelligent maintenance focuses on the full prediction of the device's future performance degradation state, rather than at some point.

Performance status diagnostics. The intelligent maintenance system has the following features:

Life Predicting - Through the analysis of the performance degradation curve of the various components of the actuator, the overall decay process of the actuator can be evaluated, resulting in the life of the actuator under different operating conditions.

Life curve.

Early warning maintenance--Troubleshooting is no longer a state quantity of 0 or 1, but a continuous value between 0 and 1. By setting the warning value, the spare parts can be replaced in advance when the component fails to reach the fault.

Never affect the normal operation of the system.

Spare parts are friendly - through the analysis of the life of the field equipment, the targeted storage of spare parts, the least spare parts, the most targeted.

Maintenance Precautions - Actuators for different operating conditions have different maintenance intervals, no longer fixed-cycle maintenance, while avoiding unpredictable failures.
