High Performance Butterfly Valves

Adjustable High Performance Butterfly Valves

High-performance butterfly valves are also called double offset or double eccentric butterfly valves. Along with their ability to withstand liquids and gases, our high-performance butterfly control valves are also made with a fireproof structure. Adding stops on our valves improves their efficiency in controlling fluid flow and preventing over-travel. Each valve is also made with a two-way pressure Class 150-900 and adjustable packing glands to ensure zero external leakages.

Made for general service, our high-performance butterfly valves are custom-made, with precise sizes, to fit your requirements and prevent problems during their application. As one of the premium high-performance butterfly valve manufacturers, DomBor Valve provides strong adjustment and installation solutions to make setting up our valves easier for any location.
