This RS PRO non-return valve stops fluids or gases in a pipeline from flowing the wrong way. For ease of use, it doesn't need to be manually or mechanically operated as it uses air pressure or fluid velocity to open and close.


Its brass construction makes it durable and resistant to corrosion for a long service life. It also has a nitrile rubber seal for a secure, leak-free join that can also withstand frequent changes in pressure.


This type of valve is commonly found in pneumatic and hydraulic applications in both domestic and industrial settings. It complies with the Restriction of Hazardous Substances (RoHS) requirements, meaning it contains only trace levels of any harmful materials.
