Straightforward planning
When planning systems with pressure-
independent combi valves, the specific
PICV to be used is determined solely by
the volumetric flow. Flow regulating valves
and balancing valves are as unnecessary
as complicated hydronic calculations.
The wide volumetric flow and differential
pressure ranges of the Acvatix PICVs enable
extremely straightforward, highly flexible
planning. Tools such as the Combi Valve
Sizer app and the HIT Portal help you with
product selection and sizing.
Straightforward installation and
commissioning
Fewer components also means less installa-
tion effort. Commissioning is fast and easy
thanks to the volumetric flow preset ability
and automatic hydronic balancing. PICVs
also permit flexible commissioning in stages
– for example, by individual floor.
Enjoy enhanced comfort while
saving energy
Although designed and balanced for a full
load, most systems actually operate under
a partial load, meaning that they operate
inefficiently. Thanks to its dynamics, a PICV
ensures that the system pressure is correct
for all loads and that pressure fluctuations
have no effect. Full stroke is available for
every setting, thus contributing to high
control accuracy. Optimal return tempera-
tures for all operating conditions guarantee
a high level of efficiency in heating and
cooling. All these factors significantly
reduce heating and cooling costs and
ensure enhanced comfort through steady
room temperature control. You achieve
energy savings of up to  percent –
without sacrificing comfort.
Siemens – of course
When installing new or renovating existing
HVAC plants, rely on efficient technologies
from Siemens. The Acvatix PICVs are innova-
tive products with state-of-the-art technol-
ogy and ideal for variable-volume, energy-
efficient HVAC applications. Available with
threaded or flanged connections, they offer
you volume flows ranging from . to
 m

/h, qualifying them for all room and
zone applications as well as heating, ventila-
tion and air conditioning systems. They are
especially suitable for refurbishments and
renovations because Acvatix PICVs permit
an efficient system even without precise
knowledge of the pipeline network.
Practical tools make your daily work easier:
• Combi Valve Sizer app for easily selecting
the right products and correct presettings
• HIT Portal for the step-by-step planning
of HVAC plants and for ordering products
directly
• BIM data for efficient planning
In addition to these tools, take advantage
of the global service network from Siemens,
with benefits that include short delivery
times and expert support if you have any
questions. And when it comes to quality,
extreme reliability in the interaction
between products and systems, and a
long service life: The products are exten-
sively tested by Siemens in the company’s
in-house HVAC laboratory.
Acvatix hydronics.
Everything under control.
Using the Combi Valve Sizer
app, you can select the ideal
Acvatix combi valve and the
right actuator with just a few
clicks. This makes planning
energy-efficient HVAC plants
very straightforward.
