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

Hale Hamilton is considered a Design Authority by many of its Defence customers. A number of our design and development personnel have specific expertise in our customer’s systems, such as submarine escape and the supply of emergency breathing air

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 thes rising pressure as flooding takes place. It must respond to the changing tower pressure, meeting the demand of the submarine escape immersion suit and maintaining a positive air supply to the escaping submariner.
