Triple Offset Butterfly Valve Textile Process DN150 PN16 WCB Cast Worm Flanged Hard Seal
Product Features
The PN16 DN300 manual worm gear flanged triple-eccentric multi-layer butterfly valve features a WCB carbon steel valve body combined with a CF3M ultra-low-carbon stainless steel disc, utilizing a differentiated alloy composition to specifically meet dual requirements for pressure resistance and corrosion resistance. It incorporates a rigid structure with GB-standard flanges, a labor-saving worm gear drive, a composite rigid-flexible multi-layer seal, and triple-eccentric frictionless opening and closing technology, it precisely addresses the selection challenges in large-diameter, medium-pressure pipeline networks with mixed operating conditions, achieving a multidimensional balance of high-strength pressure resistance, long-term corrosion resistance, zero-leakage operation, and low-cost operation and maintenance.
Product Advantages
● To address the self-weight of the DN300 large-diameter butterfly disc and the opening/closing resistance caused by the PN16 medium-pressure differential, the worm gear reduction transmission ratio has been specifically optimized, and the heavy-duty meshing structure has been upgraded. This significantly enhances torque amplification efficiency, allowing a single operator to effortlessly perform smooth full-stroke (0–90°) opening and closing as well as stepless, precise flow regulation, thereby eliminating the cumbersome, jerky, and labor-intensive operation typically associated with large-diameter valves.
● Based on a proven three-dimensional triple-eccentric design—with a dual-eccentric mechanism (valve stem eccentricity + butterfly disc eccentricity) at its core—and enhanced by precise eccentric optimization of the sealing cone angle, the opening and closing motion trajectory of the large-diameter butterfly disc has been reengineered.
● It employs an industry-proven multi-layer stacked sealing structure that combines the dual advantages of flexible seals—which provide elastic contact—and metal seals—which offer rigid impact resistance—thereby overcoming the performance limitations of single-seal designs.
