Non-return valves are essential safety and performance components in steam turbine setups. They ensure the safe, efficient and controlled operation of the system by preventing backflow, regulating steam flow, and providing isolation capabilities. Quick Closing Non-Return Valves (QCNRV) are designed to prevent backflow to the turbine from extraction and bleed lines. https://www.inditechvalves.com/quick-closing-non-return-valves/
