Here are the key factors to evaluate. ### Media Type Consider whether the fluid is corrosive, abrasive, or cryogenic — this determines body and seal material selection. ### Pressure & Temperature Match the valve pressure class and material grade to your operating conditions and ASME B16.34 limits. ### Mounting Type Floating ball valves suit smaller sizes; trunnion-mounted designs are preferred for large-diameter, high-pressure applications. ### Actuation Needs Manual lever, gearbox, pneumatic, electric, or hydraulic — choose based on frequency of operation and automation requirements.

What certifications do XINTAI ball valves hold?+ XINTAI ball valves hold API 6D, API 600, API 602, API 624, ISO 9001, ISO 14001, ISO 15848, ISO 45001, CE/PED, SIL, PAT, and TAT certifications — ensuring compliance with standards required by major EPC contractors worldwide. What size range do XINTAI ball valves cover?+ Our ball valves range from 1/2″ (DN15) to 48″ (DN1200), covering pressure classes from ASME Class 150 to Class 2500. Custom sizes and pressure ratings are available upon request. What is the typical lead time for orders?+ Standard ball valves typically ship within 15–30 days after order confirmation. Large-diameter, high-pressure, or custom-material valves may require 30–60 days. We maintain stock of common sizes for faster delivery. Can XINTAI provide custom ball valve solutions?+ Yes. We offer full customization including special alloy materials (Inconel 625, Monel 400, Duplex 2205, Super Duplex 2507), extended bonnets for cryogenic service, anti-sulfur trim (NACE MR0175), and custom actuation packages. Do you support third-party inspection?+ Absolutely. We welcome inspections from SGS, Bureau Veritas, Lloyd’s Register, TÜV, and other agencies. Our dedicated testing center is equipped for hydrostatic, pneumatic, and fire-safe testing per API 607. What is the difference between floating and trunnion ball valves?+ In a floating ball valve, the ball is held in place by seat compression. In a trunnion design, additional mechanical anchoring reduces seat stress. Trunnion-mounted valves are preferred for larger sizes (typically 6″ and above) and higher pressure classes where torque and seat load become critical. ## Ready to Source Ball Valves from China?
