Bleeding and Venting Valves / Combined Bleeding and Venting Valves

Combined Bleeding and Venting Valves


Bleeding and venting valves remove air or gases from systems or pipelines without requiring an external energy input. When a system is drained they act as venting valves.

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.

The bleeding and venting valves EB 1.76 are float-controlled compact devices for aggressive fluids. The body is made of Duplex or Superduplex. The valve cone is soft sealed. The minimum pressure required for valve seal is 0.2 bar.

Maintenance work can be done from above at the installed valve.
