Resilient seated butterfly valves DN 40 – 800 wafer and lugged versions, optimized for the food and beverage industry

Features

• Top bushing absorbs actuator side thrust loads.
• Dirtscraper prevents moisture penetrating into the shaft area.
• Actuator flange acc. ISO 5211.
• High solid, glossy, silicone free, paint system ensuring excellent corrosion resistance.
• Body locating holes ease installation and centering between the flanges.
• Sealed body splits prevent moistures from penetrating behind the seat (up to DN 300).
• Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and bubble-tight shut-off.
• The seat is field replaceable and fully isolates the body and stem from the flow.
• Primary stem sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere.
• A secondary shaft sealing provides back-up safety.
• A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
• The thin disc provides the very minimum obstruction to flow (up to DN 300).
