Dual Expanding Plug Valve

Manufactured under licenced from ARFLU, Spain

The Dual Expanding Plug valves produce a watertight closure both upstream and downstream, being used in different sectors.

  • Storage tanks
  • Loading and unloading stations
  • Multi-product distributors
  • Measuring stations
  • Aviation fuel services
  • Transfer of custody units
  • Marine platforms

    The design of these valves allows closure on both sides and venting in the valve chamber (double block & bleed). Since its sealing mechanism is not based on friction and wear on the closing elements we prevent product loss and contamination, in addition to meaning a long life
