Precision-Engineered Floating Ball Valves for Critical Pipeline Applications

Manufactured to ASME B16.34 / API 608, 150LB through 600LB, sizes 1/2″ to 10″, available in WCB, CF8, and CF8M with NACE MR01-75 compliant options.

Overview

2pc floating ball valve is the most common flanged type ball valve whose body is two pieces structure. It can be divided into 2pc flanged ball valve stainless steel 304(CF8), 316(CF8M) and 2pc flanged ball valve carbon steel (WCB) according to valve materials. The two pieces floating ball valve can be produced especially according to NACE MR01-75 and API607 & API6FA.
