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.

  • High Performance Butterfly Control 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 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. High Performance Butterfly Valves – Torex 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

    The Flowserve High Performance Butterfly Valves – Torex are technically and financially strong alternative to other valve types, especially larger valves. High tightness class in combination with a short face-to-face makes it suitable for many applications within pulp and paper, chemical and petrochemical, oil and gas, power plants, and steel works.
