The air valve (AV) with with big release cross section and patented roll-on joint membrane is perfectly suitable to release major amounts of air. The valve seat is not in contact with the medium. The AV operates at continuously variable pressure from 0.2 - 16 bar. The roll-on membrane and the spring mechanism absorb water hammers.
The integral flushing connection serves for maintenance purposes. By connecting a flushing line, dirt can be flushed out of of the AV easily and quickly. In case of major dirt, the function unit has to be dismantled, cleaned and re-installed.
The AV is provided with a ventilation hood as a standard feature. Optionally, the AV can be provided with an adaptor to connect a sufficiently dimensioned vent line (to be provided by the customer) instead of the ventilation hood.
Please note: AVs contain compressed air. Prior to any maintenance work AVs shall be put out of operation and depressurized via a ball valve!
