"Rugged" describes the Valtek ShearStream Ball Valve. Designed to overcome the problems of harsh, particle entrained processes, ShearStream also 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:

  • Piping forces that unevenly load the seal
  • Low rangeability due to limited orifice characterization
  • Unsatisfactory shutoff capabilities

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.
