Hale Hamilton (Valves) Limited

Hood Inflation System

Hood Inflation System (H.I.S) Pressure Controller:

Hale Hamilton is considered a Design Authority by many of its Defence customers.  The HIS system valves comprise a primary pressure regulator, a main pressure controller and a charging connection. At the ‘heart’ of the system is the HIS Pressure Controller. This valve is mounted in a submarine’s escape tower and tracks the rising pressure as flooding takes place. It responds to the changing tower pressure, meeting the demand of the submarine escape immersion suit and maintaining a positive air supply to the escaping submariner.
