This non-return valve from RS PRO prevents fluids or gases in a pipe network from travelling in the wrong direction. This kind of valve is often used in domestic and industrial plumbing systems.


The valve has a brass body, making it long-lasting and resistant to rust. It also has a nitrile rubber seal that can tolerate frequent pressure changes and ensures a leak-free connection with a pipe.


This valve is Restriction of Hazardous Substances (RoHS) compliant, so it contains only minimal amounts of any harmful materials. For ease of use, it doesn't require any manual or mechanical operation as it relies on air pressure or fluid velocity to open and close. Use it for a variety of pneumatic and hydraulic applications.
