What should buyers review when comparing plug valves with ball valves from China valve manufacturers?

Buyers should review the internal closure design, size range, pressure rating, body material, end connection, operation mode, and design safety features. For example, the PLV600 plug valve is available in NPS 2 to 40 inches with ratings from Class 150 to Class 1500. The BVF206 floating ball valve is available in NPS 1/2 to 12 inches with ratings from Class 150 to Class 600. The BVT207 trunnion ball valve is available in NPS 2 to 40 inches with ratings from Class 150 to Class 1500.

What is the structural difference between a plug valve and a ball valve?

The PLV600 plug valve has a bolted bonnet and split body with a fixed plug inside. The BVF206 floating ball valve has a bolted bonnet and split body with a floating ball inside. The BVT207 trunnion ball valve has a bolted bonnet and split body but contains a fixed ball. All three include a blow-out proof stem, fire-safe design, low emission packing, and anti-static design.

For large-diameter on-off isolation, is the plug valve or ball valve reference more suitable?

Both the PLV600 plug valve and the BVT207 trunnion ball valve cover sizes from NPS 2 to 40 inches and pressure ratings from Class 150 to Class 1500. The BVF206 floating ball valve covers smaller sizes from NPS 1/2 to 12 inches and ratings from Class 150 to Class 600. The more suitable model depends on process fluid, connection standard, operation mode, and site specification.

What certification points should be checked when sourcing industrial plug valves or ball valves from China?

ISO 9001 and product certifications such as API 600, API 6D, CE, and PED can be reviewed. EG Valves Manufacturing Co., Ltd states that its valves are made under ISO 9001-certified processes and that its factories hold API 600, API 6D, CE, and PED certifications. Valves can be manufactured to ANSI, DIN, BS, and JIS standards or to customer requirements.
