FAQ: Gas Ball Valves Expert FAQ

1. What are the typical body materials for gas ball valves?

Commonly used materials include ASTM A105 (carbon steel) for oil and gas, F316L stainless steel for corrosive or offshore applications, and duplex alloys for high chloride or sour gas service. Material selection is based on pressure class and fluid compatibility.

2. What is the difference between fully welded and split-body gas ball valves?

Fully welded valves provide superior integrity for buried or high-pressure lines—no flanged joints, reduced risk of external leaks. Split-body types feature easier serviceability and are generally used above ground or in process skids.

3. Which international standards govern design and testing?

gas ball valves must comply with API 6D or ISO 14313 for pipeline valves, and be tested per API 598/ISO 5208 for ensure hydrostatic and pneumatic seat/leak tightness. Fugitive emission testing per ISO 15848-1 is increasingly required.

4. What is a typical pressure rating and service temperature?

Pressure classes from PN16/150# up to PN420/2500# are available; temperature ratings go from –46°C (cryogenic) up to +425°C (hot oil/gas).

5. How are gas ball valves installed and maintained?

Installation involves precise welding or flange bolting; seat injection and stem packing may be refilled in-line for some types. Top-entry designs allow inspection or replacement without pipeline removal.

6. What is the typical warranty and traceability?

Leading manufacturers, including HBYS, offer a 24-month warranty. Valves feature heat number/mill tracing, full EN10204-3.1/3.2 certification, and can support RFID/QR code for project traceability.

7. Are third-party inspections (TPI) and documentation provided?

Yes, all major international projects require TPI (BV, SGS, Lloyds) witnessing of main pressure/hydro and seat tests, along with a complete QA/QC dossier as per project or EPC requirements.

8. How is on-site support or aftersales handled?

Remote/onsite commissioning is available for full solution supply. HBYS offers rapid spare parts, 24/7 technical hotline, and lifetime engineering consultation as optional service package.
