Precision Flow Control: Unveiling Concentric Butterfly Valves by Shengao

Shengao proudly introduces its innovative series of concentric butterfly valves, tailored meticulously for the rigorous demands of the oil & gas industry. Drawing from the principles of concentricity, these valves present a unified center where the shaft, disc, and valve body are aligned, leading to consistent and reliable sealing. Unlike offset configurations, Shengao's concentric design guarantees uniform pressure distribution, ensuring enhanced lifecycle and reduced maintenance needs. Accommodating diameters ranging from 3 to 24 inches (DN 80-600), these valves epitomize flexibility, adeptly handling tasks from hydrocarbon refinement to liquid cargo transfer. Meeting ASME 150 and 300 standards, each unit is bolstered with a resilient polymer liner. In terms of material selection, options span from the dependable carbon steel to the rust-resistant capabilities of 316 or duplex stainless steel. Shengao's relentless commitment to ensuring seamless operation and minimization of leakage positions them at the forefront of sophisticated valve technology.
