The DIN3202 F6 PN25 Cast Steel Swing Check Valve (DN200) is a heavy-duty non-return valve designed for large-scale industrial pipelines. The F6 standard specifies a specific face-to-face length, while the PN25 rating ensures it handles up to 25 bar of pressure.
Its swing-disc design allows for full-flow capacity with minimal pressure drop. Built from cast steel, it is durable and ideal for preventing backflow in water, oil, and steam systems.
