What are PICVs?
PICVs are the best solution for the control of flows through air handling units,
fan coil units and chilled beams fed from variable flow heating and cooling systems.
A PICV is a valve that can be fitted in heating and chilled water systems to provide:
Flow control, flow regulation and differential pressure control
This means that each PICV replaces up to three separate valves that would otherwise be required
(i.e.regulating valve, two port control valve, plus a differential pressure control valve).
The right PICV for each application
We strongly believe that every player should do his best make the most of energy resources and PICVs offer the potential of improved control of thermal comfort and significant energy savings.
Achieving the best possible performance from the valves and, as a consequence, improving HVAC systems sustainability.
For this reason, we developed “The Definitive Guide to PICVs” to explain to designers, installers and commissioning specialists the functions of the valves and their behaviour when installed in real systems.
Pettinaroli PICVs
meet the needs of any hydronic systems
With over fifteen years of experience and more than one million PICVs sold worldwide,
at Pettinaroli we have developed a full range of Pressure Independent Control Valves
capable of satisfy any requirement of each hydronic systems designed.
Our catalog includes “linear” and "equal percentage" characteristic as well as “axial” or “rotary” PICVs.
Compact design dirt-free diaphragm
Dynasty range of PICVs has been designed with
the added benefit of operating in heavily contaminated water.
The valve has a linear characteristic and it has also been designed
to allow the internals to be removed, clean and replaced
without effecting the performance of the valve.

Applications
Dynasty range of PICVs has been designed to provide flow limitation and temperature control of heating and chilled water systems to terminal units.
92 Series valve gives good control of water to water heat exchangers and is ideal for use in Heat Interface Units were water quality is difficult to maintain, due to the difficulty in accessing every unit.
Dynasty 92 Series valve can also be fitted in valve assemblies to be connected to Fan Coil Units.
Features
& Benefits
- Compact size
- Easy maintenance
- Dirt-free diaphragm
- Linear Characteristic
- Minimum pressure required for start-up
- Thermal and electro-mechanical actuators available
EvoPICV is a combined constant flow limiter and full stroke, full authority equal percentage temperature control valve.
EvoPICV is suitable for use in variable and constant temperature systems and may be used as a constant flow limiter in constant volume systems (without an actuator head) or as a true PICV in variable volume systems.
Applications
The control valve shutter has an intrinsic equal percentage characteristic, suitable for water-to-air terminal units, such as fan coil units, chilled beams or air handling units.
It can be maintained by using a dedicated tool and uni-directional; suitable for installation in either the flow or return pipework.
Features & Benefits
- Equal percentage characteristic
- Suitable for use in variable and constant temperature systems
- Combined constant flow limiter and temperature control valve
- Thermal and electro-mechanical actuators available
