Continuous Bleeding & Venting Valves

Air Release Valves


Continuous bleeding & venting valves are used to remove air which accumulates in systems as a plant is in operation. They incorporate a lever system which enables them to operate at both very low and high pressures.


Our EB1.12 and EB1.32 continuous bleeding and venting valves are the most popular and best-selling models. These units are the “go-to” air release valves for use in ballast treatment systems (water ballast systems), specifically for installation on ballast tank air heads. Over the years we have seen these units used in various water and wastewater solutions, built with many different market-leading technologies.
