Design and Manufacturing Standards
The Marine U-Section Double Flange Butterfly Valve adheres to internationally recognized design and manufacturing standards. The core design follows the API 609 standard, ensuring compatibility and performance in diverse industrial applications. Additional standards such as ASME B16.10 and BS EN 558 are also incorporated to guarantee dimensional accuracy and operational reliability.
The valve's flange connections are designed to meet ASME B16.5 and EN 1092 specifications, ensuring seamless integration with existing piping systems. Optional JIS 5K-20K connections are available for specialized applications. A notable safety feature is the anti-blow out stem, which prevents accidental disengagement during operation, enhancing user safety.
Material Composition
The Marine U-Section Double Flange Butterfly Valve is constructed using high-quality materials selected for their durability and resistance to harsh environments. The body is made from ASTM A536 ductile iron, which provides exceptional strength and impact resistance. The disc is crafted from aluminum bronze (C95400, C95500, C95800) or stainless steel (CF8, CF8M, CF3, CF3M, 2205, 2507), ensuring corrosion resistance and longevity.
The stem is manufactured from premium alloys such as 13CR, SS304, SS316, and Inconel 718, which are engineered to withstand high-pressure environments. The seat is available in EPDM, NBR, Buna-N, and Viton, offering flexibility for different media types and temperature ranges.
Quality Control and Testing
SAVVY VALVES employs rigorous quality control measures to ensure the Marine U-Section Double Flange Butterfly Valve meets the highest standards of performance. Every component undergoes 100% chemical analysis and mechanical testing for raw materials. Castings are subjected to DPT testing, with MT or UT testing performed as needed. Hydraulic tests are conducted to verify shell and seal integrity, while low-pressure air tests ensure leak-proof performance.
These stringent protocols align with API 598 and API 6D standards, guaranteeing the valve's reliability in critical applications. The company's commitment to quality is further reinforced by its warranty policy, which includes a minimum 12-month service life and free spare parts and maintenance instructions during the warranty period.
Application Scenarios
The Marine U-Section Double Flange Butterfly Valve is designed for use in a wide range of industries, including marine, oil and gas, water treatment, and chemical processing. Its robust construction and compliance with international standards make it ideal for applications requiring:
- High-pressure environments (PN6–PN25)
- Corrosion resistance in seawater and chemical media
- Reliable flow control in pipelines
- Seamless integration with ASME, EN, and JIS flange systems
For example, in marine applications, the valve's anti-blow out stem and corrosion-resistant materials ensure safe and efficient operation in saltwater environments. In industrial settings, the valve's precise dimensional accuracy and leak-proof design minimize downtime and maintenance costs.
