BERZICO Butterfly Valve BBFL is a high-performance industrial wafer type butterfly valve designed for reliable pipeline flow control. Manufactured with precision engineering and stringent quality control, this valve ensures long-lasting performance in demanding applications. As a trusted product from Rossonix Co., Limited, we bring over a decade of export experience (since 2011) to deliver valves that meet international standards.
Our BBFL series features a compact wafer-style body that simplifies installation between flanges, saving space and reducing weight. The valve offers excellent shut-off and regulation capabilities, making it ideal for water treatment, HVAC, chemical processing, and general industrial pipelines. With multiple material options and actuator compatibility, it can be customized to suit specific system requirements.
The butterfly valve is designed for minimal pressure drop and bubble-tight sealing, ensuring efficient operation and low maintenance. Below we highlight key technical specifications and advantages.
Key Features & Technical Specifications
Compact Wafer Design – Suitable for tight-space installations, reduces overall pipeline length and weight.
Bubble-Tight Seal – Resilient seat (EPDM, NBR, or PTFE) provides zero leakage in both directions.
Low Operating Torque – Optimized disc profile minimizes torque requirements, allowing manual or automated operation.
Full Liner Protection – Body liner isolates the body from the medium, preventing corrosion and extending service life.
Versatile Actuation – Can be equipped with lever handle, gearbox, pneumatic actuator, or electric actuator.
Wide Pressure & Temperature Range – Suitable for PN10/16 (or ANSI 150) and temperatures from -10°C to +120°C (depending on seat material).
Multi-Position Stop Plate – 10-position stop plate allows infinite flow regulation (on lever-operated models).
ISO 5211 Mounting Flange – Direct mounting for actuators without brackets (top flange design).

Why Choose BERZICO BBFL Butterfly Valve? The valve's robust construction ensures reliable operation in systems where flow control and isolation are critical. Its wafer type design not only saves space but also reduces the number of gaskets and bolts required, lowering installation costs. The resilient seat provides excellent resistance to abrasion and chemicals, while the full liner protects the body from corrosive media. Additionally, the ISO 5211 top flange simplifies actuator mounting, enabling easy automation. End users benefit from reduced maintenance downtime and extended valve life due to the corrosion-resistant materials and efficient sealing.
For high-cycle applications, an optional gearbox or pneumatic/electric actuator can be integrated to achieve precise remote control. The valve's low-torque design also allows manual operation with a simple lever handle, even for larger sizes. Each valve undergoes hydrostatic and seat leakage testing before shipment to ensure 100% compliance with performance specifications.

Frequently Asked Questions (FAQ)
Q: What is the difference between wafer and lug type butterfly valves?
A: Wafer type butterfly valves are clamped between two pipe flanges with bolts passing through the valve body. They are lighter and more compact. Lug type valves have threaded inserts on the body, allowing one side of the pipeline to be dismantled independently. BBFL series is wafer type, ideal for general shut-off and regulation where line maintenance is not critical.Q: Can this valve be used for high-temperature applications?
A: The maximum operating temperature depends on the seat material. With EPDM seat, the range is -10°C to 120°C; with NBR up to 80°C; with PTFE up to 200°C (but PTFE may require special disc coating). Please specify your temperature requirements when ordering.Q: What actuators are compatible with the BBFL valve?
A: The valve’s top flange conforms to ISO 5211, allowing direct mounting of gearboxes, pneumatic, or electric actuators. We can supply ready-to-mount solutions upon request. Lever handle is standard for manual operation.Q: How do I choose the correct disc and seat material for my media?
A: For clean water and neutral liquids, standard ductile iron disc with nylon coating is sufficient. For corrosive media (e.g., acids, seawater), stainless steel disc (SS316) and PTFE seat are recommended. For oil and fuel, NBR seat is a good choice. Our technical team can advise based on your fluid composition.Q: What pressure ratings are available?
A: The BBFL series is designed for PN10/16 and ANSI 150. Higher pressure ratings (e.g., ANSI 300) are available on special order. Contact us for custom requirements.Q: Is the valve bidirectional? Does it provide bubble-tight shut-off in both directions?
A: Yes, the resilient seat design ensures bubble-tight shut-off in both flow directions. The valve is fully bidirectional for isolation applications.Q: What is the typical lead time?
A: For standard sizes and materials, lead time is approximately 15-25 days after order confirmation. Customized versions may take 30-45 days. We offer express shipping options for urgent orders.Q: Do you provide certificates of material and testing?
A: Yes, we can provide material certificates (EN 10204 3.1), hydrostatic test reports, and seat leakage test reports upon request. Our ISO9001 quality system ensures traceability.
