Engineered valves
Description
IRELAND products range is very wide and it covers most of common needs as regards industrial valves for cryogenic service and for oxygen service.
Many options are available and our engineering as well as our highly qualified staff enable IRELAND to manufacture valves as per your own specifications.
Hence, most of the valves we manufacture are out of the scope of our standard products because of:
- the requested sizes
- the service pressures
- the flowing mediums
- the requested materials of construction
- the functions for which our customers intend our valves
- The accessories that equip our valves
