This non-return valve from the RS PRO range is designed to prevent fluid or air from flowing the wrong way. It doesn't require any manual operation, making it easy to use.


The valve has a brass body that's long-lasting and corrosion-resistant for a long working life in harsh environments. Its robust design makes it resistant to stress and vibrations that often occur in plumbing systems. Its maximum operating pressure of 16 bar makes it suitable for use in high-pressure applications.


The valve comes with an inspection cap so you can easily verify that it's working properly. This type of valve is commonly used to prevent contamination of water or damage to equipment in plumbing and pipeline systems. It's also a good choice for preventing fluid from mixing and allowing for the circulation of pressure in gas lifts.
