Covna’s Industry Advantages

High-Efficiency Design

Covna’s expansion butterfly valves are designed for high-efficiency performance, ensuring stable operation in extreme high-temperature and high-pressure environments. By optimizing valve structure and fluid dynamics, Covna’s valves improve system efficiency by 15%. In industries such as petrochemicals, they reduce failure rates, ensuring continuous and safe operation.

Wear Resistance

Covna’s expansion butterfly valves use high-hardness alloy materials that resist wear from high-speed water flow and particles. This significantly extends the valve’s lifespan. In industries like coal mining and quarrying, testing shows that Covna valves last twice as long as traditional valves, reducing replacement frequency and downtime, lowering overall operating costs. Defying abrasive flows, they sustain efficiency in mineral processing systems.

High Sealing Performance

Covna’s expansion butterfly valves use advanced sealing technology to ensure no leakage in high-pressure and vacuum environments. Withstanding pressures up to 1500 PSI, these valves have passed rigorous pressure and temperature tests and are widely used in high-sealing-demand applications such as natural gas transmission and chemical engineering, ensuring safety and stability.

Easy Maintenance

Covna’s expansion butterfly valves feature a simple, compact design that allows for easy disassembly and maintenance, reducing unnecessary downtime. The modular design allows users to quickly replace worn components and perform routine maintenance, reducing maintenance costs by 30%. In high-load production environments, Covna valves have 25% lower annual maintenance costs compared to similar products.
