The air valve with unique roll-on membrane is perfectly suitable to release major amounts of air under operating pressure. The valve seat is not in contact with the medium. The air valve operates continuously from 0 to 16 bar, perfectly sealing even when unpressurized. Moreover, the roll-on membrane and the spring mechanism absorb water hammers.
The air valve is provided with a flushing connection. By connecting a flushing line, dirt can be flushed out of of the air valve easily and quickly. In case of major dirt, the interiors have to be dismantled, cleaned and re-installed.
Please note: air valves contain compressed air. Prior to any maintenance work air valves shall be put out of operation and depressurized via a ball valve!
