SmartX PIBCV Summary
SmartX PIBCV valves and Actuators can be used with actua-
tors for pressure independent balancing and control applica-
tions or without actuators for automatic flow limiting balance
applications.
PIBCVs immediately react to all changes in system pressures,
providing stable valve control independent from the fluctuating
pressures in the piping system. No valve authority, pressure
calculations or complicated valve flow setting calculations are
required. At partial system load there is no resulting overflow
because the valve always limits the flow corresponding to the
design flow of the coil.
SmartX PIBCV valves with actuators include an integrated
control valve with flow regulation for HVAC applications, plus
an automatic flow limiting function for energy efficiency. A full
range of Schneider Electric actuators are available for every
control application including two position, proportional, floating,
spring return open, spring return close, and non-spring return.
Applications
Variable flow systems: A SmartX PIBCV with a Schneider
Electric actuator is used as a control valve for terminal units,
like an AHU (Air Handling Unit), FCU (Fan Coil Unit) or radiation
panel, and controls the required flow on every terminal unit
maintaining hydronic balance in the system.
Constant flow systems: There are numerous applications in
which SmartX PIBCV can be used. In a constant flow system
with FCUs or in a one pipe heating system, SmartX PIBCVs
can be installed as an automatic balancing valve in every riser.
SmartX PIBCVs limit the flow to the set value, thus automatically
achieving hydronic balance. Whenever an automatic flow
limiter or a control valve is needed, the advantages of cost-
saving properties are inherent with SmartX PIBCVs. This
includes systems with (floor) heating/cooling, concrete core
activation or radiation panels.
