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.

Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
The Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
The Power Plant Check Valve has small fluid resistance, the medium channel inside the valve body is straight through, and the flow direction of the medium does not change when it flows through the check valve. The pressure self-tightening seal is used, and the two ends of the valve are usually welded. The valve flap closes quickly, the water hammer pressure is small, the body structure is simple, the production process is good, the sealing performance is good, and the sealing surface is less eroded when fully opened. A wide range of applications.
