Butterfly Valves

Ideal for precision throttling and on-off applications, especially in lighter-weight piping systems, the Flowserve family of butterfly valves is often specified for its versatility. Outstanding throttling accuracy for process control is achieved through low-friction, erosion resistant sealing surfaces with very low operating torques.

Featured Solutions

  • Flowserve Valtek High Performance Butterfly Valves valdisk

    The Valtek Valdisk™ is a double offset butterfly valve used whenever high capacity is needed with the lowest possible pressure loss.

    Features & Benefits 

    • Low profile, low weight body provides a low cost solution
    • Double offset shaft lifts the seat quickly out of the seat to minimize seat wear and allow low torque for great control
    • Metal and soft seat options provide tight shutoff in both flow directions

  • Flowserve Valtek Double Offset Contol Butterfly Valves ValdiskBX

    The Valtek Valdisk BX is a double offset butterfly control valve designed to meet the most routine and the most rigid service requirements. Learn more about control valves and butterfly valves from BBP.

    FEATURES & BENEFITS

    • Low profile, low weight body provides a low-cost solution
    • Double offset shaft lifts the seat quickly out of the seat to minimize seat wear and allow low torque for great control

  • Flowserve NAF Triple Offset Butterfly Valves Torex

    High-performance, triple-offset, metal- or soft-seated butterfly valve frequently used for isolation or on-off applications, but equally suitable for control, especially on high-flow, low-pressure applications.

    FEATURES & BENEFITS

    • Longer service life provided by triple-offset design, which minimizes seat wear during opening and closing
    • Minimized pressure loss and low energy costs due to tight shutoff
    • Low installation costs enabled by compact wafer design and low weight
    • Improved safety assured by Safety Integrity Level (SIL) 3 and IEC 61508 certification
    • Increased uptime — even in difficult media and demanding pressures — through excellent design, materials and performance characteristics

  • Flowserve Valtek Segmented Ball Valves ShearStream HP

    The Shearstream HP Segmented Ball Valve is a segmented, ball control valve that provides exceptional control and rangeability for the process industries. Learn more about control valves available from BBP.

    • Segmented ball controls very low flow rates and can open up to large flow rates, resulting in a 300:1 turndown
    • Segmented ball provides shearing action as it moves through the seat to cut through debris and provide reliable shutoff
    • Metal, soft, and heavy duty seat options provide reliable tight shutoff for a variety of applications and process conditions
