Temperature of medium [°C] –20 … +80 –10 … +60
Higher piston speeds can be achieved on the return stroke of single
and double-acting drives with the quick exhaust valves VBQF.
Compressed air flows from the control valve via the VBQF to the drive. The
exhaust port 3 is closed at this time.
When the pressure at 1 falls, exhaust flow occurs from 2 to 3.
In order to implement a quick exhaust, the VBQF must be attached directly to
the supply port of the drive. The VBQF can be mounted in any position and can also be turned.
The VBQF is available with or without silencer.
