Fittings with a non-return valve allow the free flow of fluid in one direction only and prevent it in the opposite direction. The direction of flow is indicated schematically by an arrow on the body of the coupling.
With a nickel-plated brass body, these fittings have a female cylindrical BSP or male cylindrical BSP outlet, an NBR oil seal, an AISI 302 steel spring and a nickel-plated brass obturator. High temperature FKM seals are available as an option.
These fittings have an opening pressure of 0.5 bar and a working pressure of 2 to 8 bar.
