1. The 2 inch butterfly valve use rubber sealing ring can be placed on the valve body or butterfly plate.
2. The cast iron wafer butterfly valve has a unique structure, flexible operation, labor saving and convenience.
3. The cast iron wafer butterfly valve plate adopts a frame structure with high strength, large circulation area and small flow resistance.
4. The soft-sealing wafer type control valve adopts a double eccentric structure, which strengthens the sealing function when closed and has excellent sealing performance.
Our heavy-duty 2 inch butterfly valve is precision-engineered for high-performance fluid isolation and throttling control within industrial piping networks. Featuring an optimized wafer butterfly configuration, this valve delivers an ultra-compact face-to-face dimension and a highly reduced total weight compared to traditional gate or ball valves. This streamlined profile significantly minimizes structural pipeline stress, lowers shipping costs, and simplifies installation in tight spatial arrangements.
Designed for rigorous operational environments, this butterfly valve type wafer model guarantees superior bi-directional bubble-tight sealing capabilities under low to medium pressure conditions. The universally engineered body features multi-standard alignment holes, ensuring this butterfly wafer type assembly seamlessly integrates with ANSI Class 150, PN10, PN16, and JIS 10K flange configurations without modification. The aerodynamic disc design reduces turbulence, optimizes flow coefficients (Cv value), and minimizes permanent pressure drops across the pipeline.
This industrial butterfly valve lever operated series is equipped with a heavy-duty, multi-position locking handle with a reinforced notch plate. The ergonomic manual lever mechanism ensures smooth, rapid 90-degree quarter-turn actuation while providing clear visual verification of the internal disc position. The precision-machined shaft and disc assembly significantly lower running torque, preventing premature wear on the resilient seat and extending the overall operational lifespan during frequent cycling.
