Pressure Reducing Systems in High-Rise Buildings
Water supply system design requirements for high-rise
buildings present unique issues:
■
Supply cut-off is unacceptable and single source supply
is common.
■
Valves are located in areas where water damage can
be extremely expensive.
■
Pressure reducing systems are often located next to
prestigious residential and office space. Extraneous
noise and maintenance activities are to be avoided.
■
The main supply line of high-rise buildings is exposed
to greater head at lower zones while pressure for the
consumer must be kept within recommended levels.
As a result, lower zone pressure reducing systems deal
with greater differential pressure.
The Model 720 Pressure Reducing Valves together
with BERMAD’S accumulated experience address these
issues and provide appropriate solutions.
