1.Full port design with ultra-low flow resistance:Adopts full port structure, minimizes fluid flow loss during pipeline circulation, suitable for high-flow fluid transmission of water, oil and gas.
2.Dual-direction sealing with zero leakage performance:Optimized sealing structure realizes reliable bidirectional tight shut-off, achieving zero leakage under rated pressure to meet strict industrial fluid isolation requirements.
3.Blowout-proof stem structure for high-pressure safety:Bottom-mounted valve stem equipped with convex step at stem head, effectively preventing stem ejection under internal medium pressure, greatly improving operation safety under harsh working conditions.
4.Lockable manual lever for convenient operation:Matched with manual operating handle with locking device, operators can lock the valve at fully open or fully closed position to avoid accidental misoperation.
5.Precision investment casting valve body:The valve body is manufactured by investment casting process, featuring smooth inner cavity, uniform wall thickness, stable structure and excellent corrosion resistance.
6.Standard flanged connection, easy installation & maintenance:Compliant with national standard flange connection, lightweight overall structure, occupies less installation space; simple disassembly structure brings convenient daily inspection and maintenance.
