RS PRO Brass Single Check Valve, BSPP 1-1/2in, 12 bar

Use this RS PRO non-return valve to keep fluid or air from traveling in the wrong direction. It's commonly used in plumbing systems in both domestic and industrial settings.


The valve is easy to use as it relies on air pressure or fluid velocity to open and close, meaning it doesn't require manual or mechanical operation. Its brass body is durable and corrosion-resistant, so it will hold up even when used in harsh conditions. The nitrile rubber seal ensures a tight, leak-free join with a pipe and is hardwearing enough to withstand frequent changes in pressure.


This valve is suitable for use in pneumatic and hydraulic applications. It complies with the Restriction of Hazardous Substances (RoHS) requirements, meaning it contains only trace levels of any harmful materials.
