Description

  • Connection under residual pressure is supported on one side for operational convenience.
  • An inspection hole ensures verification of complete coupling connection.
  • Stucchi VOFX series dimensions are fire-tested in compliance with API 16D and EUB Directive #36 for safety assurance.
  • Newly treated threads prevent premature wear, enhancing durability.
  • Wrench flats on the bodies simplify fitting assembly.
  • The poppet valve with an elastomer seal ensures maximum sealing when couplings are disconnected.
  • Stainless steel retainers provide superior strength and corrosion resistance.
  • Internal components are designed to minimize turbulence and reduce pressure drop, optimizing performance.
  • High resistance to pressure impulses, tested for 500,000 cycles, ensures reliability.
  • The compact design allows for easy integration and efficient use of space.
  • The system is designed to be simple and user-friendly.
