Resilient Seated Double Flanged Butterfly Valve - BFD

The Resilient Seated Double Flanged Butterfly Valve from Challenger Valves is a high-quality valve designed and tested in accordance with AS4795.2 standards. It is OceanaMark certified by IAPMO Oceana (License No: OMK32262) and WaterMark certified (License No: WM-032262), ensuring compliance with industry standards. The rubber and coating used in the valve are approved to AS4020 for added assurance of quality and safety.

This butterfly valve is suitable for end-of-line service and isolation, with a full 16-bar range achievable by removing the downstream flange. Its bi-directional bubble-tight sealing ensures a reliable and leak-free operation. The vulcanized seat is securely held in position, making the valve suitable for vacuum applications.

The valve's construction features a high-strength one-piece through-shaft secured by precision taper pins, providing a strong and reliable connection between the disc and stem. This design allows for field replacement if needed. Additionally, the blow-out proof stem ensures operator safety and eliminates OH&S concerns.

To enhance durability and extend valve life, the heavy-duty shaft bushing absorbs side thrusts and promotes disc alignment, reducing wear. This feature contributes to the valve's longevity and overall performance.

In summary, the Resilient Seated Double Flanged Butterfly Valve is a high-quality product that meets industry standards and ensures reliable performance. With its certifications, superior sealing, robust construction, and safety features, it is a trusted choice for various applications. Choose the Resilient Seated Double Flanged Butterfly Valve from Challenger Valves for its exceptional quality and reliability.
