Type DBIplug-valve-double-block-bleed-inspection-service

The AZ-Armaturen double block and bleed valve is a plug valve with two independent sealing areas which provide a tight seal against pressure from both ends of the valve. Additionally, the cavity between the sealing areas can be vented/bleeded (DBI Type A) in order to recognise a leakage on one sealing immediately.

The AZ-Armaturen double block and bleed valves are used in critical applications where any kind of leakage is not allowed to occur. Furthermore, the valve can be fitted upstream and/or downstream with additional inspection valves (Type B & C).

This provides the advantage of inspection capabilities of the medium and draining possibilities for revision-service. The AZ-Armaturen double block and bleed valve can be operated manually or fully actuated.


The AZ sales team is looking forward to assisting you with all your technical questions.
