CBF02-TA01 Operation and Maintenance Manual DOWNLOAD

1. Reinforced Hard-Back EPDM Seat
Enhanced Seat Integrity: The seat features a robust, hard-backing layer that prevents deformation under pressure, ensuring consistent bubble-tight sealing (EN 12266-1 Class A) and extending service life.
Excellent Sealing Resilience: The EPDM sealing surface provides superior elasticity for reliable shut-off against water, air, and many mild chemicals.
2. Stainless Steel (SS) Disc for Longevity
Corrosion-Resistant Core: The CF8M (316 Stainless Steel) disc provides strong resistance to rust and corrosion, making it suitable for humid, water-based, and mildly corrosive environments.
Durable and Lightweight: Offers a strong, long-lasting flow control element without the excessive weight of cast iron.
3. Compact and Efficient Wafer Design
Space-Saving Installation: The wafer body installs quickly between two pipeline flanges, saving significant space and weight compared to lug-style valves.
Cost-Effective Solution: Simplifies installation and reduces total project costs for general industrial and building service applications.
4. Reliable and Simple Operation
Smooth Manual Actuation: Designed for easy operation with a standard hand lever, providing clear visual indication of open/closed positions.
Low Maintenance: The combination of a durable SS disc and a robust rubber seat minimizes wear and maintenance needs in standard service.
