GB High Platform WCB Ball Valve

The GB-standard high-platform ball valve in WCB material meets Chinese industrial requirements (GB/T 12237). Designed for small-bore pipelines (DN20/25), it handles PN16 pressures in steam, oil, or water systems. The high-platform stem facilitates actuator mounting, and the floating ball design ensures reliable sealing under thermal fluctuations. 

Unlike DIN valves, GB standards prioritize domestic compatibility, with threaded or flanged ends per GB/T 9113. The WCB body is hardened for wear resistance, and the PTFE seats offer a 150,000-cycle lifespan. It’s commonly used in power plants and HVAC systems. Testing includes shell strength and sealing checks per GB/T 13927.
