Device tests flashback arresters

Witt-Gasetechnik offers stainless steel FBA testing device 722 for testing gas system flashback arresters and gas nonreturn valves up to the DN50 flange size.

The device performs four different tests: leak-tightness, safety against reverse gas flow, functionality of the pressure-controlled cutoff valve, and validation of the correct gas flow rate.

The test device weighs 12 lbs. and is operated with nitrogen or oil-free air. In combination with the clamping device 743, it can test a large number of devices rapidly. Changing between sizes and types is simple, the company reports.
