Combined bleeding valve for sea water and small to very high flow rates

The bleeding and venting valve GOLIA 3F (EB 1.76) is a combined startup and continuous bleeding and venting valve with guided float. During startup large air quantities are discharged at low pressure via a large seat. If the bleeding valve is closed and further small volumes of air accumulate during continuous operation, a second seat arranged within the float opens and discharges the accruing air. The large cone does not open until the level is going down at simultaneous pressure release. In the event of a vacuum the valves open immediately.
