This non-return valve from RS PRO allows you to control the direction of fluid flow in your systems. The valve has an arm with a plate mounted inside it that is pushed open by the pressure of the fluid. However, any movement in the opposite direction will force the plate back against a seal, preventing the flow. The direction of flow is clearly marked on the side of the valve.
The bronze construction of this valve ensures it's safe for use with steam, water and oil. Depending on the temperature, it can also be used with pressures up to 20 bar. The two ends of the valve are built with 1.5-inch female screw threads, allowing threaded pipes to be screwed straight into the end, making assembly as easy as possible.
