Features
1、Compact Structure, Strong Load-Bearing Capacity: Featuring a flanged connection structure, the valve body possesses high rigidity, enabling it to withstand significant pipeline stress. The multi-disc louver design results in a compact overall structure, offering a smaller footprint for the same flow area.
2、Quick Opening/Closing, Excellent Synchronization: Employing a 90° rotary operation, the multiple louver blades are linked via a connecting rod mechanism, allowing for rapid and smooth opening and closing. The synchronized action of all blades ensures high regulation accuracy.
3、High Flow Capacity, Low Pressure Loss: When the valve is fully open, the multiple louver blades align parallel to the flow direction of the medium, creating minimal obstruction. The louver design increases the flow area, making it particularly suitable for large-diameter, low-pressure differential gas media pipelines.
4、Reliable Sealing Performance, High Temperature and Wear Resistance: Utilizing a metal-to-metal hard seal structure, the sealing pair consists of stainless steel or heat-resistant alloy materials. This design withstands thermal expansion and thermal shock from high-temperature gases, offering resistance to wear and erosion, ensuring a long service life.
5、Easy Maintenance, Low Inspection and Repair Costs: The louver blades and shaft feature a detachable structure, facilitating on-site inspection and replacement. The connecting rod mechanism is designed for rational adjustment, simplifying commissioning and effectively reducing maintenance costs.
6、Wide Applicability: The valve body can be made from materials such as carbon steel, stainless steel, or heat-resistant steel. This allows it to be suitable for demanding conditions involving high-temperature flue gas, dust-laden gas, and corrosive gases. It is widely used in ventilation, dust removal, and flue gas treatment systems across industries such as power, metallurgy, building materials, and chemical engineering.
