6" Non Return Valve Dn150

The Dn150 non-return valve, which has a diameter of 6 inches, is part of a complex hydraulic system in which the fluid is regulated for safe flow. Its main function is to prevent the backflow of fluid into the system, which is a precaution in the case of a water supply or central heating system. This metal valve, with a robust appearance, is manufactured from high-quality materials to guarantee long life and resistance to high pressure and corrosion. Inside the valve, there is a moving disc that suddenly rotates in its position, passing the flow in the desired direction, but, as soon as the counter-rotation begins, it stops under pressure and closes securely. It is used in urban and industrial structures, where efficiency and safety in fluid systems take first place.
