Planning is so easy
When you plan a system using PICVs,
your choice of PICV depends solely on
volumetric flow. There’s no need for
flow regulating valves, balancing valves,
or complicated hydraulic calculations.
That’s why PICVs are ideal for refur-
bishment and renovation jobs, where
you don’t have precise knowledge of
the pipe network.
Siemens makes it even easier to utilize
PICVs. The “Combi Valve Sizer” app
calculates maximum volumetric flow
and the presetting you need. It will
guide you through the choice of valve
and actuator, and can directly check
your commissioning settings.
Installation and commissioning
are so easy
You’ll complete the installation process
faster since you need fewer compo-
nents. Adjustable volumetric flow and
automatic dynamic hydronic balancing
make commissioning quick and effort-
less. PICVs also allow for commission-
ing in stages, e.g. one story at a time,
which gives you lots of flexibility.
Enjoy comfort and save energy
PICVs are dynamic valves that ensure
the right system pressure for all load
conditions and prevent pressure fluc-
tuations from impacting on room
temperature. With PICVs from Siemens
you have full stroke for each presetting,
which helps ensure maximum control
accuracy. Ideal return temperatures
for all operating conditions guarantee
a high level of efficiency in heating
and cooling. That means you can
achieve energy savings of up to
30 percent with no loss of comfort.
