This series of high temperature back pressure valves is designed for temperature applications that exceed the maximum 140 degrees F rating of our standard valves with PVC tops. These valves come standard with an aluminum top, Viton diaphragm and metallic spring discs.
Optional materials, connections and styles are available.
The maximum pressure rating for valves, regardless of size, is 150 PSI at 73 degrees F. As with all other thermoplastic piping components, the maximum non-shock operating pressure is related to temperature. Above 100 degrees F refer to the chart on How To Order Top Valve under downloads.
