Frequently Asked Questions (FAQ)

Q: Are Audco ball valves fire-safe certified?

A: Yes, Audco ball valves are tested and certified to API 607 / ISO 10497 fire-safe standards, making them suitable for flammable media.

A: Absolutely. Every valve comes with complete 3.1 Material Test Certificates (MTC), pressure testing certificates, and factory warranty documentation.

A: Floating ball valves rely on line pressure to push the ball against the downstream seat (ideal for lower pressures/smaller sizes). Trunnion-mounted ball valves support the ball mechanically at the top and bottom, reducing operating torque in high-pressure, large-bore pipelines.
