Scald Protection in Airplane Galley Faucets

April 15, 2019

From their design and manufacture to daily operations, airplanes must be a well-oiled machine to ensure strict schedules are kept and passengers and crew are safe while on board. Most people think of safely taking off and landing as the only concern, but there are a lot more elements to protecting people than just that such as preventing scalding from over-temperature water.

Normally airplane galley faucets don’t produce water hot enough to scald. However, when a coffee maker’s boiling water back flows through a shared manifold, the dangerously hot water can be released from a faucet.

Our thermostatic scald protection HAT valve prevents this back flow of potentially scalding water. Installed between the manifold and faucet, the valve continuously senses the temperature of the water flowing through it. When the temperature rises to the HAT valve’s set-point due to over-temperature back flow, the valve automatically closes to interrupt flow. Only once the water has cooled to below the valve’s set-point will it open and re-establish flow.

The HAT valve is unaffected by pressure variations, so while passenger’s ears are popping as the plane ascends or descends, our valve continues to function correctly protecting both crew and casual hand-washers. It is offered in 1/2″ and 3/4″ sizes and functions completely mechanically, requiring no source of electricity to operate. 100% Made In America with stainless steels components, the HAT is corrosion resistant and has a guaranteed long service life with no required maintenance.

Our HAT scald protection valve is trusted by thousands of commercial and private aircraft to protect their crew and passengers. Installations include the Airbus 380, Airbus A330, Airbus A350, Boeing B747, Boeing B777 and Boeing KC-46A Tanker.
