Double check valve with test port and compression ends - brass plug
These check valves are monodirectional devices, allowing the backflow prevention of fluid under pressure. They are normally used in domestic water installations, booster pump systems, heating systems, central heating systems, heat generators (wall-mounted boilers, solid fuel generators, heat pumps). 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 characteristic concerning the installation position. The peculiarity of this range of valves is the presence of two check valve inserts and one test port between the two inserts. The double check valve creates an intermediate chamber to separate with more safety the downstream fluid from the upstream fluid, avoiding any backflow toward the upstream circuit. The test port can be used to check the correct working of the downstream check
valve.
This valve can be used as antipollution device in potable water systems.
