This non-return valve from the RS PRO range stops gases or fluids in a pipe network from flowing in the wrong direction. It's a common feature in plumbing systems as well as a range of pneumatic and hydraulic applications.


No human intervention is required to operate this component, as it relies on fluid velocity or air pressure to open and close, making it easy to use. It's made from brass for durability and resistance to corrosion, while its nitrile rubber seal ensures a secure, leak-free join with a pipe and withstands frequent pressure changes effectively.


You'll find this type of valve in a range of domestic and industrial environments. As it complies with the Restriction of Hazardous Substances (RoHS) requirements, it contains only trace levels of any harmful materials.
