This RS PRO non-return valve prevents air or fluid from flowing the wrong way. It's made of a highly durable brass material that's resistant to corrosion, making it suitable for use in harsh environments.


The valve is designed to withstand the stress and vibrations that commonly occur in plumbing systems. It's suitable for high-pressure applications of up to 16 bar and is fitted with an inspection cap so you can easily check on its working function.


This valve is easy to use as it requires no human intervention to operate. It's commonly used in plumbing and pipeline systems to prevent water contamination and equipment damage, as well as in gas lifts to allow for pressure circulation and prevent fluid mixing.
