Data Sheet



Resilient Seated Wafer Butterfly Valve - BFW

The Resilient Seated Wafer Butterfly Valve from Challenger Valves is a high-quality valve designed and tested in accordance with AS4795.1 standards. It is OceaniaMark certified by IAPMO R&T Oceania (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, highlighting its quality and reliability.

This wafer 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. The blow-out proof stem enhances 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.

The Resilient Seated Wafer Butterfly Valve is suitable for high repetition, actuated applications. Its precision disc machining ensures a mirror image of the seat profile, enhancing low torque operation and reducing liner wear. The ISO interface flange allows for interchangeability and standardization of actuation equipment.

The stem seal connection is ensured with molded double "O" rings, providing a reliable seal, along with an additional upper stem seal for greater design integrity.

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