Flowserve Corp., a leading global provider of fluid motion and control products and services, has introduced the Valtek ShearStream SB segmented v-port type ball control valve, as well as the newly upgraded ShearStream HP with heavy-duty seat.
The broader family of Flowserve ball control valves offers the exceptional control, reliable engineering, and excellent support that are needed for demanding applications in the chemical, oil and gas, pulp and paper, and power industries.
The ShearStream SB offers: standard metal and soft seat options that provide tight shutoff for ANSI Class 150 and Class 300 service; V-ring stem packing with a combination of virgin PTFE and carbon-filled PTFE in the standard configuration for long-lasting, fugitive emission-tested, sealing protection; and a Turnex high-performance actuator. The actuator is direct mounted for better control and fewer parts, and has a double-acting piston and precision linkage connection for accurate control and high-torque output.
The ShearStream HP design offers a broader array of options, which allows for higher temperatures, higher pressures, unique materials and special designs. The HP is newly upgraded with a heavy-duty seat option. For applications with high-pressure drops, the heavy-duty seat provides tight shutoff and reliability. The heavy-duty seat is available in metal (Class IV) and resilient UHMWPE (Class VI) seal materials.
