Valves and systems for naval ships and submarines

Hale Hamilton’s primary strength is in the provision of valves and systems used on naval ships and submarines worldwide for the storage, distribution and application of compressed air, nitrogen and oxygen. The valves typically operate at supply pressures from 6,000psi (~414bar) down to below 100psi (~7bar).

Hale Hamilton's greatest strength is the knowledge, experience and commitment of its staff.
