The NABIC 500F Flanged High Lift Safety Valve has been designed primarily for use on unvented hot water heating systems, where a high capacity, emergency steam relief capability is required. The NABIC 500F has a high capacity and resilient PTFE seating, also make it ideal for steam, air, and inert gas applications. A PTFE to Viton seating design is also available where greater seal tightness is required. NABIC Valves now come with an Industry leading 5 Year Guarantee.
