BU Series
Bypass Circuit Unit allows reducing pressurization time for the parts with large volume, which helps reducing the total test time.
It also reduces test time.
Air Leak Testers can control Air operated valve(s) of the Bypass Circuit Unit.
There are Single, Dual and Triple valves. Select an ultimate one depending on the shape and volume of the tested parts.
E/P Regulator Bypass Circuit Units are available for Air Leak Testers
●Circuit is selectable among Single, Dual and Triple depending on the shape and volume of the part to be tested.
