Barberi® check valves are monodirectional devices, allowing the backflow prevention of fluid under pressure. They are normally used in hydraulic systems, booster pump systems, heating systems, generic industrial and agricultural water systems. Sealing is permitted through forces exerted by a spring and by the fluid pressure against a gasket which guarantees the seal even at very low back pressures. Moreover, the force of the spring allows the valve to have a universal characteristics concerning the installation position.
