Features
1、Extended Bonnet Design, Reliable Low-Temperature Sealing: The extended bonnet structure effectively isolates the low-temperature medium from the stuffing box, ensuring the packing operates at near-ambient temperature. This prevents the packing from freezing and failing, guaranteeing the valve's sealing performance and operational reliability under low-temperature conditions.
2、Excellent Low-Temperature Sealing Performance: The sealing pair of the disc and seat utilizes a tapered or flat sealing structure. Through precision grinding and pairing, combined with low-temperature elastic gaskets or self-energizing sealing design, it maintains good specific sealing pressure under low-temperature conditions, achieving tight shut-off and effectively preventing internal leakage of the medium.
3、Low Fluid Resistance, Optimized Flow Path: The valve body features a streamlined channel design, providing a smooth transition for the medium flow. This significantly reduces flow resistance and pressure loss, making it suitable for low-temperature systems sensitive to pressure drops.
4、Bevel Gear Transmission, Light and Labor-Saving Operation: Equipped with a bevel gear transmission device, the gear reduction mechanism significantly lowers the operating torque. This is especially suitable for large-diameter or high-pressure class low-temperature valves. The opening and closing process is smooth and controllable, effectively reducing operating effort while maintaining precise control of the valve position.
5、Low-Temperature Adapted Material, Durable and Economical: Main components are made of corrosion-resistant materials suitable for low-temperature conditions, such as LCB, LC3, and CF8. The structure is robust, ensuring a long service life. The overall design is simple with fewer potential failure points, making routine maintenance and seal replacement relatively convenient.
6、Widely Applicable for Low-Temperature Media and Large-Diameter Pipelines: Specifically designed for pipeline systems handling low-temperature media like liquefied natural gas, liquid oxygen, liquid nitrogen, liquid argon, and low-temperature ethylene. It is particularly suitable for large-diameter pipelines or low-temperature applications requiring frequent operation or higher operating torque, meeting the demands of industries such as petrochemicals, air separation, and liquefied gas storage and transportation for large-diameter low-temperature valves.
