Resilient Seated Lugged Butterfly Valve - BFL

The Resilient Seated Butterfly Valve from Challenger Valves is a top-quality valve designed and tested in accordance with AS4795.1 standards. It is OceanaMark certified by IAPMO R&T Oceana (License No. OMK32103) and WaterMark approved (License No. WM-032103), ensuring compliance with industry standards. Additionally, it is WSAA accredited with an appraisal number: PA 2102, further emphasizing its quality and reliability.

This butterfly valve has undergone water quality testing and approval to AS4020, ensuring its suitability for water applications without compromising water quality. Its bi-directional bubble-tight sealing ensures a reliable and leak-free operation in both flow directions. 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.
