PSB Globe Valve
9 products found
A PSB globe valve (Pressure Seal Bonnet globe valve) is a linear-motion modulating valve engineered for zero-leakage flow regulation in ultra-high-pressure, high-temperature utility systems. Rather than relying on bolt preloading to compress a gasket, the PSB design utilizes a self-energizing, tapered metal-to-metal sealing structure. As internal pipeline pressure rises, it forces the bonnet upward against a wedged gasket, driving it tighter into the body cavity. This mechanism ensures that higher system pressures naturally create a tighter seal, eliminating joint relaxation and fugitive emissions. Available in straight-through or Y-pattern body configurations, the internal flow paths are contoured to guide high-velocity media while minimizing turbulence and fluid erosion. Power plant operators and process piping design engineers can maximize system runtime and eliminate high-pressure steam leakage by importing certified PSB globe valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
