ShearStream SB
Designed to overcome the problems of harsh, particle entrained processes, ShearStream™ provides accurate, reliable control in a broad range of applications, including chemical, power and petroleum.
ShearStream™ addresses and solves many long-standing challenges faced by traditional ball valves, such as:
ShearStream™ achieves Class IV shutoff with a metal seal and Class VI with a soft seal. A spring-loaded heavy duty seat is available for high pressure applications in metal and soft seat configurations. In addition to the standard wafer body design, ShearStream™ is available with separable or integral flanges. ShearStream™ is also available in sizes 1” through 12” and 16”, ANSI Classes 150, 300 and 600, and in stainless steel, carbon steel and other alloys.
- Piping forces that unevenly load the seal
- Low rangeability due to limited orifice characterization
- Unsatisfactory shutoff capabilities
