Navy takes control of water

Honeywell water control valves are
being installed on the Royal Navy’s
new aircraft carrier, HMS Queen
Elizabeth, to prevent excessively hot
water in baths, showers and basins.

Marine engineering valve
specialist, Score Marine, is installing
50 Honeywell Kombi 4 throttle
valves for automatic hot water
balancing and 142 Honeywell
TM200VP thermostatic mixing
valves on the ship the largest ever
built for the Royal Navy.

The Honeywell TM200VP is
certified to the highest Buildcert
standard for thermostatic mixing
valves, TMV3, and ensures a
constant safe temperature at the
point of delivery by blending hot and
cold supplies to provide a uniform,
safe preset temperature.
Domestic hot water on the ship
will be stored at at least 60 degrees C
to avoid legionella and distributed at
50 degrees C minimum, which is
dangerously hot for bathers. So the
Honeywell TM200VP fail-safe
mixing valves are essential at the
outlet to prevent scalding.
