Manufactured to internationally recognized dimensions and pressure ratings (PN16/PN25), these valves are designed for seamless installation and integration into existing fluid systems, offering peace of mind and operational consistency.

FAQs of Stainless Steel Duplex Valve:

Q: How does the Duplex Stainless Steel composition improve valve performance in marine and chemical environments?

A: Duplex Stainless Steel, including grades 2205, 31803, S32750, and S32760, enhances the valves corrosion resistance, mechanical strength, and resistance to stress corrosion cracking. This makes the valve highly reliable and durable in harsh marine and chemical processing environments.

Q: What applications and media are suitable for this Duplex Valve?

A: This valve is designed for industrial fluid control, water treatment, and chemical processing applications. It handles a wide range of media such as water, oil, air, and chemicals, making it versatile for numerous industrial uses.

Q: Where can the Stainless Steel Duplex Valve be installed?

A: It can be installed in facilities requiring robust flow control, such as water treatment plants, chemical processing plants, and marine installations. Its flanged design enables easy integration with piping systems adhering to ASME B16.5 or EN1092-1 standards.

Q: What process is used for manufacturing and testing the valve?

A: The valve undergoes a casting process to achieve its flanged body structure. Each unit is rigorously tested using both hydrostatic and pneumatic methods to verify its strength, integrity, and adherence to leakage and pressure standards.

Q: How is leakage prevented in this valve?

A: Leakage is minimized by using high-quality PTFE, EPDM, or metal seals, combined with precision engineering that achieves Class VI (bubble tight) leakage standards. This provides secure shutoff and reduces risk during operation.

Q: When should you choose a quarter-turn versus a multi-turn operating mechanism?

A: Quarter-turn mechanisms are ideal for quick on/off and isolation, while multi-turn designs provide finer flow control, especially in applications that require gradual regulation of media.

Q: What are the benefits of the polished or shot-blasted surface finish?

A: A polished or shot-blasted finish enhances corrosion resistance, facilitates easier cleaning, and improves the valves overall appearance, ensuring both functional longevity and suitability for demanding industrial environments.
