Flanged Ball Valve - 5801F Series

5801F Series Fire Safe Flanged Valves

Overview

The 5801F Series full port valve is API 607 certified fire safe flange ball valve. It has specially designed seats that provide tight shutoff and low torque. Standard features include dependable, fully contained double body seals, anti-static devices and blow-out proof stems. The full port valves have a full diameter, straight, construction-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.
