Design
Different 3 ways design: L or T or Y
4 ways can be also manufactured
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.
