BVFW Cast Iron Wafer Style Butterfly Valve with Lever
I. Wafer Style:
Designed to fit between two flanges in a pipeline, secured with bolts that pass through the valve body.
The four-hole design ensures the valve is properly centered and securely fastened, enhancing stability.
2. Tongue-and-Groove Seat:
This design includes a groove in the valve body and a tongue on the seat, ensuring a tight and reliable seal.The tongue-and -groove mechanism helps align the valve accurately during installation, improving sealing performance and reducing leakage risks
Equipping your facility with the right flow control mechanisms drastically reduces the risk of system failures. This butterfly valve is engineered with distinct advantages that directly translate to improved operational efficiency and reduced lifecycle costs for your demanding projects.
Uncompromising Structural Integrity: The heavy-duty cast body absorbs mechanical stress and thermal shock, preventing micro-fractures during rapid temperature fluctuations in active pipelines.
Precision Throttling Capabilities: The internal globe mechanism allows operators to finely tune flow rates, mitigating dangerous water hammer effects and protecting sensitive downstream equipment.
Simplified Maintenance Architecture: The bolted bonnet and standardized flanged ends permit rapid disassembly and in-line servicing without requiring complete removal from the piping network.
Friction-Optimized Stem: The precisely machined valve stem minimizes operational torque, ensuring that manual handwheel adjustments remain consistently smooth and effortless over decades of continuous use.

Navigating the technical specifications of high-pressure flow control systems can be complex. Below are detailed answers to the most common inquiries regarding our butterfly valves, designed to assist your engineering and procurement teams in making informed decisions.
Can the handwheel operation be retrofitted with a pneumatic actuator post-installation?
Yes. The valve is designed with a standardized mounting architecture that allows for the seamless removal of the casting handle and the subsequent installation of pneumatic or electric actuators without needing to remove the valve body from the active pipeline.
How does the CF8M (SS316) material differ from CF8 (SS304) in terms of application suitability?
CF8M includes the addition of molybdenum, which significantly enhances its resistance to pitting and crevice corrosion, particularly in chloride-rich or highly acidic environments. It is the preferred choice for harsh petrochemical, marine, or offshore applications.
Are these valves fully compliant with API 598 testing standards?
Absolutely. Every unit is subjected to rigorous API 598 inspection and testing protocols prior to shipment. This includes high-pressure hydrostatic shell tests and seat leakage tests, ensuring zero-defect performance upon delivery.
What is the typical process for customized valve configurations based on proprietary drawings?
Our engineering team reviews your custom drawings within 48 hours to assess feasibility and material requirements. Once approved, we utilize our advanced casting facilities to produce precise prototypes, ensuring the final product perfectly matches your unique spatial and pressure requirements.
How does the flanged end design impact routine maintenance procedures?
The ANSI B16.5 compliant flanged ends allow for straightforward bolt-on installation and rapid decoupling. This facilitates highly efficient in-line maintenance, significantly reducing operational downtime during routine system inspections or component replacements.
