Product Details<\/strong><\/span><\/h3>\n

Overview<\/strong><\/span><\/h4>\n

The D371X worm gear flanged butterfly valve is a high-performance industrial valve designed for medium to large pipeline systems. Its flanged connection ensures structural integrity and reliable sealing under pressure. The worm gear mechanism enables smooth 90\u00b0 opening and closing, requiring minimal effort while providing self-locking functionality for stable positioning at any angle. This valve is widely used for on-off and throttling service across water, oil, gas, and corrosive media.<\/span><\/p>\n
