Flowserve Expands Valtek ShearStream Family

Now Includes Both Standard and High-Performance Ball Control Valve Applications

Flowserve Corporation, 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.

With these product introductions, Flowserve continues its commitment to providing superior technology in rotary control valve products. 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 new ShearStream SB control valve is the standard choice for segmented v-port ball control valve applications. Standardized designs provide the most cost competitive ShearStream solution in a rugged design.

The ShearStream SB offers:

l Standard metal and soft seat options that provide tight shutoff for ANSI Class 150 and Class 300 service.

l V-ring stem packing with a combination of virgin PTFE and carbon-filled PTFE is the standard configuration for long-lasting, fugitive emission-tested, sealing protection.

l 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.

The ShearStream HP offers the following options:

l Several fugitive emission packing combinations.

l 300 to 1 rangeability

l ANSI Classes 150 to 600.

l Stainless steel, carbon steel, most cast alloys.

l One to four-inch sizes in heavy-duty metal seating.

l One to 12-inch sizes in heavy-duty soft seating.
