Flanged ball valves - 6801F Series

6801F Series Flanged Valve

Overview

The 6801F Series is a world class API 607 certified fire safe flanged ball valve available in full port construction. Specifically designed seats provide tight shutoff and low torque. Full port valves have a full diameter, straight, constriction-free flow path, giving about the same flow capacity as a similar size piece of pipe. Full port valves are used when flow capacity / pressure drop is the most important consideration, or when frequent cleaning with a flush or pig is required.
