differential in supply and return temperatures to provide
high operational efficiency of the chiller or boiler.
• Improved Comfort
– The SmartX PIBCV valves are not affected by other
valves in the system that may be opening and closing
throughout the day or other piping system disturbances
providing more constant, comfortable, room
temperatures.
• Reduced Pumping Costs
– A reduction in overflows through the network reduces
pumping costs. A smaller pump head and equipment is
required compared to traditional configurations.
• Reduced Installation Costs
– Only one valve needs to be installed rather than two
or three since the SmartX PIBCV covers the pressure
balancing, flow limitation and control modulation.
• Easy and Quick Commissioning
– SmartX PIBCV setup time is significantly reduced with
a simple and accurate flow setting procedure without
the need for flow charts, calculations or measuring
equipment.
• Improved Reliability
– Improved mechanical equipment reliability from
reduced actuator movements.
Product Description
The SmartX PIBCV range is a comprehensive selection of
automatic balancing and control valves that provide flow
limitation, with full control authority over hydronic regulation.
Automatic balancing within PIBCV valves provide stable flow
regulation regardless of pressure fluctuations in the system
and all valves have an adjustable flow limitation set point. The
control valve portion of the PIBCV further regulates the water/
glycol flow from close-off up to the maximum flow limit setting.
Typical applications are temperature control of chillers, air-
handling units, heat exchanges and terminal units such as fan
coils, induction units and radiant panels.
Features
• Reduced Energy Consumption
– Pressure independence ensures no overflow of water/
glycol through the valve. Limiting water/glycol flow to the
design load of the coil has a significant effect on energy
efficiency since systems operate for the majority of the
time on a partial load.
– The overflow of water/glycol causes a degradation
in heat transfer at the heat exchanger. Uncontrolled
overflow of water/glycol beyond the design flow of the
heat exchanger is an extremely wasteful and inefficient
use of heat.
– The correct and maximum design flow ensures a high
