Design

Designed with a full or reduced bore, and screwed or bolted connections, DARCO ball valves can be manufactured with a large panel of materials (Carbon or stainless steel, Duplex, super Duplex…).

Options
  • The option of overlay on sealing pockets can also be proposed.
  • The ball-seats contact could either be with polymers or with metal-metal. Our trunnion valves used both with Single Piston Effect (SPE) or Double Piston effect (DPE) design.
  • Vent and drain plugs can be added
  • Stem extension can be proposed
  • Optionally, some injection points on seats and stems can be added.
  • Operated by lever, wheel, gearbox, actuator or dead man.
