The 6801F Series is a world class API 607 certified fire safe flanged ball valve available in full port construction. Specially 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 sized 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.
