Rückschlagventil 1„1 / 2 De Dietrich 94914284

A non-return valve with a 1"1/2 connection is a key part for larger heating systems, allowing fluid or gas to flow in one direction only. This prevents reverse flow that could damage boiler or burner components. Ideal for use in pipelines where backflow protection is critical, this valve supports the safe and efficient operation of heating equipment. Its size makes it suitable for medium to large installations, and it integrates easily into existing pipework for maintenance or upgrades.
