A: A 3-piece ball valve has a center section that can be removed without taking the valve out of the pipeline. This allows easier replacement of seats, seals, and the ball. It is preferred for applications requiring frequent maintenance, while 2-piece valves are more compact and economical for general on/off service.
Yes. We supply threaded ends in NPT, BSP, and BSPT. Also socket weld and butt weld ends. All threads are gaged per ASME B1.20.1. Please specify your end connection when requesting a quote.
We do. Our 3-piece ball valves can be configured for cryogenic service down to -196°C with extended bonnets, stainless steel trim, and low-temperature seat materials. Certificates per BS 6364 available.

“We replaced a major US brand with Thriveon’s 3-piece valves. Annual savings of $47,000 with zero failures in 18 months. Their engineering team helped us select PEEK seats for our superheated steam application.”
– Tom H., Senior Piping Engineer, Louisiana“The OEM process was smooth – they customized the stem length and added a NACE trim for our offshore platform. Lead time was only 22 days including certification docs. Highly responsive.”
– Maria C., Supply Chain Manager, Gulf Coast“I was skeptical about direct China sourcing. But after visiting their Hebei factory and seeing the QA lab, I was convinced. Three years later, they remain our primary valve supplier.”
– David K., VP Operations, Midwest EPC“Their 3-piece ball valves are perfect for our hygienic CIP applications. Full port, 316L finish, and they provided FDA certification without extra charges. Shipping from Tianjin in 18 days.”
– Amanda R., Plant Engineer, Wisconsin“We ordered 600 units for a water treatment expansion. Every valve passed hydrotest on arrival. The cost was 38% lower than our previous distributor. Fast, professional, reliable.”
