Type: CBF02-TA03--Product Catalog
Lightweight and Space-Saving–The wafer design eliminates integral flanges, reducing overall weight and allowing installation in tight piping layouts where space is limited.
Fast Installation–Simply center the valve between two standard pipe flanges and tighten the flange bolts. No special tools or complex procedures required.
Lower Cost–With less material and simpler machining than lug or flanged designs, wafer valves offer excellent value for general-purpose applications.
High Strength–Ductile iron offers approximately twice the tensile strength of gray iron, providing reliable performance under PN16 pressure surges.
Impact Resistance–The nodular graphite structure withstands mechanical shock and pipeline vibration.
Corrosion Protection–Combined with standard epoxy coating (250μm minimum), the body resists corrosion in water and wastewater service.
Replaceable Seat Design–The seat is not bonded to the body but mechanically retained, allowing replacement in the field without removing the valve from the pipeline–simply loosen the disc, swap the seat, and reassemble.
Excellent Water Resistance–EPDM offers outstanding resistance to water, steam, and outdoor weathering, making it ideal for water supply, wastewater, and HVAC applications.
Wide Temperature Range–Maintains sealing properties from -20℃ to +120℃, covering the full range of typical water system operating temperatures.
Good Corrosion Resistance–CF8 provides reliable resistance to oxidation and corrosion in water, mild chemicals, and atmospheric exposure.
Non-Toxic and Safe–Suitable for potable water and general service applications.
Durable and Lightweight–Offers good mechanical strength while keeping the disc weight manageable for smooth operation.
Self-Locking Design–The gear operator is self-locking, so the disc stays in position even under flow pressure–no need for additional locking devices.
Open-Close Position Indicator–Built-in indicator shows valve position at a glance, making it easy for operators to confirm open/closed status.
Reduced Operating Torque–The gear ratio multiplies manual input torque, making operation smooth and effortless–particularly important for 14-inch valves where hand lever torque is too high for comfortable operation.

Every wafer butterfly valve undergoes rigorous quality control at our LRQA-audited ISO 9001:2015 certified facility:
100% hydrostatic testing (shell and seat) per EN 12266-1 / API 598–with bubble-tight shut-off certified.
Dimensional inspection against customer-approved drawings–flange drilling, face-to-face, and disc alignment verified.
Material verification with traceable mill test certificates (MTC)–CF8 disc and DI body fully documented.
ISO 9001:2015–Quality management system (certified by LRQA)
CE–EU safety compliance
WRAS–UK drinking water approval (available for EPDM-seated designs)
DNV / ABS–Marine approval (available on request for offshore projects)
LRQA is the world's first certification body to be awarded UKAS accreditation to deliver ISO 9001 certification, and our certification demonstrates that our quality management system follows a robust, globally recognised approach focused on continuous improvement and risk management.
The advantages and what it means for you:
