Design and Manufacturing Standards
The Marine U Section Double Flange Butterfly Valve is designed and manufactured according to the API 609 standard, which ensures compatibility and performance in industrial applications. Additional norms can be applied based on customer requirements. The valve's face-to-face (F to F) dimensions adhere to ASME B16.10 and BS EN 558, ensuring seamless integration into existing pipeline systems. The connection types, including ASME B16.5 and EN 1092, provide flexibility for various industrial applications.
A key feature of the valve is its anti-blow out stem design, which prevents the stem from being ejected under high-pressure conditions, enhancing safety and reliability. This design aligns with the rigorous standards set by NIST for industrial equipment, ensuring compliance with global safety protocols.
Materials and Construction
The valve's construction uses high-quality materials to ensure durability and performance in harsh environments. The body is made from cast iron and ductile iron, providing excellent strength and corrosion resistance. The disc is crafted from aluminum bronze (C95400, C95500, C95800) and stainless steel (CF8, CF8M, CF3, CF3M, 2205, 2507), which offer exceptional resistance to wear and tear. The stem is constructed from 13CR, SS304, SS316, and other high-performance alloys, ensuring longevity and reliability.
The seat materials include EPDM, NBR, BUNA-N, and VITON, which provide excellent sealing properties and compatibility with a wide range of fluids. These materials are selected to meet the NIST guidelines for material performance in industrial applications.
