Description
Barberi® swing check valves are monodirectional devices, allowing the backflow prevention of fluid under pressure. They are normally used in heating systems, central heating systems, heat generators (wall-mounted boilers, solid fuel generators, heat pumps), thermal solar systems, generic industrial and agricultural water systems. The inner hydraulic seal is obtained through the forces exerted by the body of a swinging obturator and by the fluid pressure against a gasket which guarantees the seal even at very low back pressures. Since these valves work with gravity force, directly acting on the swinging obturator (clapet or swinging obturator), they don’t have a universal characteristics for the installation position. The advantage of these valves is the low head loss thanks to the body round shape and the big bore obtained from the swinging movement of the obturator; these features make these valves also work silently. There are versions with rubber-metal seal (060 and 125) or metal seal (080) used especially with thick or less liquid fluids (for example sewages). Swing check valves (060, 080) are equipped with a plug to inspect the valve.
