D371F4-10C DN50 PN16

Lined butterfly valve is designed for shut-off and control of corrosive and chemically aggressive media. The wetted parts are lined with fluoropolymers that protect the valve body against corrosion and provide reliable tight shut-off in demanding process conditions. The valve is suitable for both manual operation and automated installations.

Advantages

• High chemical and corrosion resistance
• Tight shut-off without metal-to-metal sealing surfaces
• Compact and lightweight construction for easy installation
• Compatible with pneumatic, electric and hydraulic actuators
• Serviceable design with inspectable lining condition
