  • Wafer High Performance Butterfly Valves
  • A73
  • GENERAL INFORMATION

    Series A73 Wafer high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.

    Significant performance makes the valve widely used in many applications such as Airport refueling, Hydrocarbon processing, HVAC, Air treatment, Chemical processing, Purified gas, Steam and vacuum services, Potable water, Powder and pulp processing, etc.
    Wafer design makes the valve convenient for connection between flanges and save length in pipe line.
