Nabic Fig 256B Pipe Interrupter
 

Pipe Interrupters are anti-pollution devices used to prevent siphonage or backflow in pipework by creating an open vent to atmosphere. Conforming to the requirements of EN1717 they are suitable for working pressures up to 10 bar and temperatures up to 60 Deg C.

The Fig 256B is classified as a DB type suitable for protecting up to fluid category 4. This device has a moving element which seals the ventilation gaps during normal flow conditions. When negative pressures occur on the inlet side which could cause siphonage, the membrane retracts seals the flow ports and simultaneously vents the outlet side of the pipe interrupter. NABIC Valves now come with an Industry leading 5 Year Guarantee.
