The Beaver F11–F12 butterfly valve has a two-piece body with a concentric design. The stem is centred in the disc and the disc centred in the bore. Such a symmetric design allows for high flow values and minimises pressure drops.
The valve’s distinguishing feature is a PTFE-lined disc complemented by a PTFE seat that covers the entire surface of the body in contact with the media. PTFE protects the valve from corrosion, making it suitable for chemical and petrochemical applications where standard elastomers will likely fail.
This butterfly valve is available with a wafer or lugged body design.
