This standard systematically defines, for the first time, the terminology, structural requirements, test methods, safety specifications, and inspection criteria for pneumatic gas-air ratio adjustment devices (hereinafter referred to as “ratio adjustment devices”). It clarifies core indicators such as gas mixing accuracy, sealing performance, high-temperature resistance, and durability, filling a gap in specialized standards for ratio adjustment devices and providing a unified technical specification and testing basis for the industry. The implementation of this standard will further regulate the application of ratio adjustment devices in the gas appliance sector, enhancing the safety, reliability, and standardization level of the gas appliance industry chain.
With over two decades of deep expertise in thermal combustion and gas control, Jingding Electric has taken the lead in drafting this national standard, fully demonstrating its comprehensive strength in the industry. The company focuses on the research, production, and technological innovation of gas proportional valves and precision ratio control components, having launched over a hundred core control components, including gas proportional valves, gas/air proportional valves, pressure regulators, control valves, and water proportional valves. These are widely used in household and commercial gas appliances such as gas water heaters, heating boilers, and stoves, as well as various industrial gas devices.
From product development to national standard formulation, from technological breakthroughs to real-world applications, Jingding Electric will continue to provide compliant, efficient, and safe core control component solutions for industry customers, helping them create safer, more energy-efficient, and more stable gas appliance products.
Cubic Sensor and Instrument has built a complete industrial layout and industry solution based on “sensors + controllers + actuators.” Gas proportional valves are key actuators for achieving safe, efficient, and low-emission combustion control in gas equipment. By leveraging Jingding Electric’s actuator technology advantages, combined with the company’s sensors and controllers, Cubic Sensor and Instrument helps the industry achieve more precise gas ratio control and more stable system operation, continuously providing strong support for the upgrade of the gas appliance industry and the intelligent development of the sector.
