Concentric butterfly valve derives its name from its structural characteristic: the centerline of the disc and seat coincides along the same axis. Its working principle involves rotating the disc mounted on the valve stem to adjust the flow passage area through the valve body, thereby achieving flow regulation or fluid shut-off. Concentric butterfly valves are commonly used in applications demanding high sealing integrity and precise medium flow control.

A motorized control valve is an automatic control valve driven by an electric actuator to open or close, enabling remote control of fluid on/off, flow regulation, and pressure adjustment, thereby enhancing the intelligence level of system operations. Compared to traditional manual or pneumatic valves, motorized control valves offer significant advantages such as high control precision, fast response speed, and strong integration. Whether in HVAC systems, petrochemical industries, power generation, or food and pharmaceutical sectors, motorized control valves play an essential role.

Silent check valve, also known as a non-slam check valve, is a high-efficiency valve that combines the dual functions of “preventing reverse flow of media” and “reducing pipeline noise.” In industrial, construction, and municipal applications, its unique structural design addresses the vibration and noise issues caused by water hammer in traditional check valves, making it a critical device for ensuring pipeline safety and enhancing system stability.

In the field of industrial automation and fluid control, multi-function valves are gradually replacing traditional single-function valves as the core component of modern pipeline systems, thanks to their innovative “one valve for multiple purposes” design. These valves integrate functions such as flow regulation, pressure control, medium switching, and safety protection, optimizing equipment layout, reducing procurement costs, and enhancing system operational efficiency and reliability.

The auto-flow balance valve is an intelligent valve that integrates flow control and automatic differential pressure regulation, designed for automatic flow control in chillers, boilers, heat exchangers, pumps, fan coil units, cooling towers, and hot water supply systems. Its core function is to ensure that each branch of the system maintains the set flow rate under varying operating conditions, achieving hydraulic balance within the system. The auto-flow balance valve can maintain constant flow rates in water systems within normal working pressure differential ranges, contributing to energy efficiency and reduced system losses, while playing a critical role in enhancing system stability.

The pressure independent control valve is an intelligent valve that integrates electric drive technology with dynamic balancing technology, primarily used for regulating flow, pressure, and temperature in fluid pipeline systems. It can automatically adjust the valve opening based on real-time operating conditions, maintaining stable flow during system load fluctuations or pressure changes. Through its electric actuator receiving control signals, it enables remote or automated precision control. Compared to traditional valves, its core advantage lies in the combination of “dynamic balancing” and “intelligent control”, which effectively resolves hydraulic imbalance issues, reduces energy consumption, and extends equipment service life.
