Use this non-return valve from RS PRO in your system to ensure that liquids flow only in the intended direction. To seal the valve, it uses an interior plate that's free to swing but that pushes on a seal when liquid is flowing in the incorrect direction.


The valve is easy to use as the flow direction is clearly labelled on the side. It has a 1-1/2-inch threaded design on each end, so it's simple to connect to compatible fluid systems.


The valve's stainless steel material ensures it's long-lasting, even when used in tough industrial environments. It's an appropriate choice for manipulating water flow or for use with hydraulic networks of up to 14 bar.
