Marwin Valve 6801 Fire Safe Flanged Ball Valve

The Marwin 6801 is an API 607 certified fire safe flanged ball valve with full port construction, 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. The Marwin 6801 can be used when flow capacity/pressure drop is the most important consideration, or when frequent cleaning with a flush or pig is required.
