Description

Flanged butterfly valve

The Flanged Butterfly Valve features a double flange design that is perfect for heavy industry, shipbuilding and other harsh vacuum applications. It comes with an ISO5211 top flange to make it easier to attach an actuator and has a stem anti-blowout design for added safety during use. The bonded seat adds further protection by preventing contact between the body and shaft with the medium being used. Other amazing features include single flange mounting, an ability to be installed in any desired position, bubble-tight shut off at full pressure rating as well as large flow capacity and enough strength. The valve is ruggedly constructed for strength and durability, making it ideal for any industrial or manufacturing environment. A true powerhouse of fluid regulation technology!

Double flanged butterfly valve features a bonded liner extending over the flanges. The double flange design is suitable for high pressure loading and for use in heavy industry, shipbuilding, severe vacuum applications and water treatment industry like potable water, water treatment and wastewater applications.
