FAQs of Swing Check Valve:
Q: How is the Swing Check Valve typically installed?
A: This valve can be installed in both horizontal and vertical pipe orientations, making it versatile for various pipeline configurations. Flanged connections that comply with international standards aid precise and secure installation.
Q: What applications are best suited for this Swing Check Valve?
A: It is ideal for industrial pipelines, water treatment plants, oil & gas facilities, and chemical processing plants. Its robust construction and compatibility with multiple media make it suitable for handling water, oil, gas, steam, and chemicals.
Q: When should I choose a soft seated versus a metal seated Swing Check Valve?
A: Soft seated valves are preferable where tight shut-off and leak prevention are critical, typically with cleaner fluids. Metal seated options suit high-temperature or abrasive applications where durability takes precedence over absolute tightness.
Q: Where do these Swing Check Valves adhere to recognized industry standards?
A: The valves conform to design and face-to-face standards such as API 6D, BS 1868, ANSI B16.10, and are compatible with end connections including DIN, BS, ANSI, and JIS, ensuring global applicability.
Q: What is the process for ensuring pressure integrity in these valves?
A: Each valve undergoes rigorous hydrostatic body and seat pressure testing, with additional pneumatic seat tests as required. This ensures the valves structural and sealing reliability under operational pressure conditions.
Q: How does the valves coating benefit its service life?
A: Body coatings, such as fusion bonded epoxy and specialized paints, provide superior corrosion resistance. This protection extends the valves operational longevity even in aggressive or chemically challenging environments.
Q: What is the benefit of a bolted bonnet design in this valve?
A: A bolted bonnet allows for easier access to internal components, simplifying inspection, repair, or replacement, and thereby reducing maintenance time and improving overall operational efficiency.
