The ventilation butterfly valve is designed with a centerline or eccentric structure to achieve low pressure drop and high flow capacity. The multi-level sealing system can withstand temperatures up to 300℃ and effectively prevent dust. The valve stem and butterfly plate are forged integrally, providing high strength and long service life. It offers various driving options such as manual, electric or pneumatic, meeting the control requirements for different working conditions. The structure is compact, maintenance is simple, and it is suitable for regulating and cutting the airflow in various ventilation ducts.

Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering.
The API 6A High Pressure Slab Gate Valve is specially designed for high-pressure pipeline systems in industries such as petroleum, natural gas, and chemical engineering. It features a valve body made of high-quality alloy steel, which is precisely machined and rigorously tested to ensure reliable performance under high pressure, high temperature, and corrosive medium conditions. The unique flat gate plate design enables two-way sealing, allowing for flexible opening and closing with low flow resistance. It is an ideal choice for long-distance pipelines, refining and chemical plants, and high-pressure fluid control systems.
The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
