PSB Gate Valve
22 products found
A PSB gate valve (pressure seal bonnet gate valve) is a heavy-duty, linear-motion isolation valve specifically engineered for ultra-high-pressure and high-temperature services, such as supercritical steam lines and mainline fossil fuel power plant loops. Unlike conventional bolted-bonnet valves where internal pipeline pressure works against the body-bonnet joint and threatens to cause leaks, the pressure seal design utilizes the internal system pressure to tighten the seal. As line pressure rises, it forces the internal bonnet upward against a specialized wedge-shaped metallic or graphite gasket, compressing it tighter against the valve body to create an absolutely bubble-tight, leak-proof boundary. This robust gate valve eliminates structural weight and maintenance headaches in severe-service steam distribution, chemical synthesis, and oil refinery refining units. Industrial procurement specialists can maximize system safety and reduce structural overhead by sourcing precision-engineered PSB gate valves directly from leading manufacturers in China via our global B2B marketplace.
