Based on the outstanding performance of the axial flow check valve, such as low flow resistance, quick closure and water hammer elimination, the butt-weld connection upgrades it from a "high-performance valve" to a permanent and highly reliable basic component suitable for high-pressure, high-temperature, highly toxic or high-purity pipelines. It realizes the "metal fusion" of valves and pipes, making it the preferred choice for key nodes that require absolute sealing and long service.
