450-PN16 Butterfly Valve WCB Body Precision Casting
Valve castings are manufactured using sand casting or investment casting processes, producing key valve components such as valve bodies, bonnets, and supports. Common materials include WCB, stainless steel, and ductile iron. The castings feature a dense microstructure, with strict control over defects like shrinkage cavities, porosity, and cracks. The internal flow passages are precisely formed and the surfaces are smooth, ensuring excellent pressure‑resistance and sealing performance. Following heat treatment and nondestructive testing, the castings exhibit stable mechanical properties and outstanding resistance to erosion and corrosion by process media. They are suitable for precision machining and assembly in gate valves, globe valves, plug valves, ball valves, and other valve types, and are widely used in industrial piping systems across sectors such as petrochemicals, gas, water treatment, and power generation.

The body and the inner wall of the plug in the lined rotary plug valve are entirely lined with corrosion‑resistant materials such as rubber or PTFE, ensuring that the metal substrate does not come into direct contact with corrosive media. This design provides excellent resistance to strong acids, strong alkalis, saline solutions, and a wide range of corrosive chemical fluids. The lining’s elasticity enables a soft seal, delivering superior sealing performance and low actuation torque, with rapid on/off operation achieved through a 90° rotation. The full‑bore flow path is smooth and free of dead zones, minimizing material buildup and crystallization. The top‑mounted construction facilitates disassembly, maintenance, and replacement of lining components, making it suitable for pipeline shut‑off applications in corrosive environments such as chemical processing, environmental protection, and textile dyeing. It can be equipped with manual, pneumatic, or electric actuators.
