Buy Pneumatic Fixed Ball Valve PN1.6/2.5 WCB Flanged Metal Seated
The VALVEHU Pneumatic Fixed Metal Seated Ball Valve is an industrial-grade solution designed for high-performance fluid control applications. With a robust construction, this valve integrates a fixed ball design with a precision-machined metal seat, making it ideal for high-temperature, high-pressure, and corrosive media environments.
This actuator-driven ball valve operates using a pneumatic control system and is compatible with input signals ranging from 4–20mADC or air pressure from 0.4–0.7MPa, enabling fast and reliable actuation. It supports multiple body materials such as WCB, CF8 (304), CF8M (316), and CF3M (316L), offering flexibility for different fluid conditions. The seat ring is hardened and treated for enhanced wear and corrosion resistance. The filling material is made from high-strength V-type PTFE or flexible graphite, ensuring reliable sealing even under fluctuating thermal conditions.
Pressure class options include PN1.6MPa and PN2.5MPa, with full-bore and flanged-end connections to standard dimensions. This industrial ball valve is designed for consistent performance in critical systems such as petrochemical, power plants, heating systems, water treatment, chemical processing, and steam pipelines.
Whether you are managing gas, steam, oil, or chemical media, this metal-seated valve is engineered to perform in severe service conditions where ordinary valves fail. The internal anti-static design and blow-out-proof stem enhance safety and durability. The modular structure simplifies maintenance and replacement, reducing operational downtime.
