Series VBH

High-pressure bifunctional air valves

Air control in high-pressure hydraulic pipelines through evacuation of large volumes during filling and air intake during emptying or under vacuum conditions.

Series VBH

IRUA Series VBH consists of double-function air valves designed specifically for hydraulic pipelines operating at high pressures. In pumping mains, long pipelines or industrial infrastructures, air management is critical to prevent overpressures and vacuums.

How a Series VBH air valve works

High-pressure double-function air valves perform two essential functions to control air in hydraulic pipelines subjected to demanding conditions.

01
Series VBH sequence 1

Evacuation of large amounts of air during filling

02
Series VBH sequence 2

The valve will remain closed during normal operation of the installation

03
Series VBH sequence 3

Air intake into the pipeline in the event of drainage or rupture
