General Construction

Trunnion ball valves feature a design that prevents axial displacement of the ball, ensuring effective sealing through line pressure. They are suitable for a wide range of applications without specific size or pressure limits and are ideal for installations where maintenance is not required.

Materials of Construction
  • Low Temperature and Low Alloy Carbon Steel
  • Stainless steel, Duplex, and Super Duplex
  • Nickel alloys
Applications
  • Oil & Gas production, processing, transportation, and distribution
  • Chemical and petrochemical refining
  • Suitable for both above ground and below ground installations
Technical Data
  • Design Standards: API 6D, API 6DSS, ASME B16.34, ISO 14313, ISO 17292
  • Design Pressure: ASME B16.34, EN 1092-1, ISO 17292
  • Temperature Range: -50° to 200°C (-58° to 392°F)
  • Pressure Range: PN20 (ANSI 150) to PN420 (ANSI 2500)
  • Size Range: DN15 (1/2") to DN1800 (72")
  • End Connections: Various standards including ASME B16.5 and MSS-SP-44
Approvals
  • Safety Integrity Level: SIL 3
  • Fire Safe: API 607, API 6FA, BS 6755, ISO 10497-5
  • Area Classification: ATEX 94/9/EC
  • Pressure Equipment Directive: PED 97/23/EC
  • Fugitive Emission: ISO 15848/1

VW3–VW4–VW5-1

esse s.r.i. trunnion & floating ball valves Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining on above ground and below ground installations. Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction STANDARD FEATURES UTILITY CORROSIVE & DIRTY low temperature!
