On November 12, 2020, the 3rd China Control Valve Expert Forum (2020 meeting) was held in Hangzhou, Zhejiang Province, and Yuan Pingren, chairman of Sichuan Waika Automation Instrument Co., Ltd., was hired as an expert of the control valve expert group of the China Instrumentation Society. Its published "Air-powered Executive Agency" paper was published in the "2020 China Instrumentation Society Control Valve Expert Forum Proceedings", which was highly praised and widely concerned by the participating experts.

The air-powered actuator is a brand-new actuator independently developed by Sichuan Wickard Company. It uses compressed air to replace traditional mechanical springs. It has high sensitivity and integrates single and double actions. It can exchange positive and reverse actions on site without disassembling the actuator. It has a series of advantages such as pre-pressure and output force can be adjusted on site. Recently, it has obtained one invention patent and one utility model patent.

Since its research and development in 2006, the air-powered actuator has been successfully used in many projects, and some projects have been used continuously for more than ten years and are still in good condition. From the long-term test results and the market promotion feedback in the pilot test, this innovative air-powered actuator cleverly solves many disadvantages brought by the defects of diaphragm actuator and piston cylinder, moreover, the structure is simple, the output force is large, the operation is stable and reliable, the assembly is easy to operate, the conversion of multiple functions is quick, the volume and weight are light, the application range is wide, and the application effect is excellent.
