Looking to stop the reverse flow of gases and fluids in your pipeline system? Try this RS PRO bronze non-return valve. The plate mounted inside its arm is pushed open by fluid pressure but is forced back against a seal when fluid moves in the opposite direction, preventing flow.


The valve is made from bronze, so it's safe to use with oil, steam and water. It can also withstand pressures of up to 20 bar for use in heavy-duty applications. For ease of use, the flow direction is clearly labelled on the side of the valve.


The valve is easy to install as each end has a 1-inch screw thread for screwing pipes directly into the end. It's commonly used in a range of industrial and domestic environments, including chemical plants, food supply chains and heating systems.
