Features & Benefits

Bray is proud to offer uni-directional, metal seated designs as an additional option to our Series F15/F30 soft seated full port flanged ball valve offerings. This option increases the temperature rating to 750°F (399°C) and enhances wear resistance, while maintaining the proven safety and reliability of existing Flow-Tek valves. With our modular, interchangeable part system, the modification kit can be used in our ASME and EN valves for sizes ranging from ½” – 6″ (DN 15-150). For specific valve dimensional data and Cv values please refer to F15/30 or F15 EN documentation.
