PICV
One Device, Three Functions
Control valve with integrated adjustable flow limiter and automatic
pressure regulator simplifies installation and commissioning.
Straight Forward & Convenient
Siemens PICV valves include an integrated differential pressure regulator that maintains constant pressure across the internal control valve and consistent volumetric flow, regardless of pressure fluctuations. This ensures optimal comfort under all operating conditions and maintains appropriate return temperatures.
Consequently, HVAC equipment, such as pumps, operate more efficiently, reducing maintenance and repair costs and significantly lowering heating and cooling expenses. The modular design of PICV valve actuators simplifies installation across the product range. Known for their reliability, these actuators complement our innovative valves, offering years of precise control.
Improve Comfort & Efficiency
Unlike conventional control valves, Siemens PICVs automatically adjust to system pressure fluctuations through their built-in differential pressure regulator. This ensures a constant flow, improving heat transfer through the coils and maximizing Delta T.
The result is enhanced energy efficiency and cost savings by preventing over-supply or under-supply of heating or cooling energy. Additionally, more accurate temperature control improves occupant comfort.
Achieve your design intent with Siemens PICV
Enjoy the freedom to choose a better solution of 2-way Pressure Independent Control Valves (PICVs) with a comprehensive portfolio from 1/2 to 6 inches. All with a 5 year warranty.
Pressure independent control valves (PICVs) improve system performance and optimize delta-T through reliable valve control. Siemens PICVs integrate three functions into a single device and always maintain their full stroke.This reduces or eliminates hunting for the right actuator setting, resulting in better control. On-site commissioning is easy thanks to max flow pre-setting and auto balancing.
PICV: "Give us a flow and we will give you a valve"
- Simple Selection: With very little information you can match an actuator to valve body and minimize downtime. No CV calculations or design considerations are necessary.
- Balancing: If your facility adds circuits because of an expansion, the flow control of existing circuits remains intact eliminating the need for re-balancing the system.
- Energy Savings: Improve savings through balancing load under any condition thus eliminating overflow and reducing pumping costs

How PICVs Work:
Hot/chilled water or 50% water-glycol solutions in closed loop systems enter the valve and pass through a variable rectangular adjustable flow limiter (C) that is connected to the ring with the dial (A) for presetting the maximum volumetric flow.
The medium then flows through the temperature control valve (D) with a linear characteristic and a stroke of 5 or 6.5 mm. A powerful spring (B) ensures safe closing.
Before leaving the valve, the medium passes through a second throttling point (E) controlled by the built-in mechanical automatic differential pressure regulator (F).This regulator is the heart of the valve and ensures that the selected volumetric flow is maintained across the whole differential pressure working range
Why Siemens PICVs?
A Smaller Footprint Matters
No matter how complicated your pipe network, Siemens pressure independent control valves are the right fit. No extra piping is required when installing any size of Siemens pressure independent control valves. No extra pipe means reduced material costs and fewer leak points.
An Easier Delta T Solution and a 3-in-1 Valve
The Siemens pressure independent control valve is a three-in-one device. A key advantage is the field adjustable flow limiter is independent of the valve stroke. By reducing the flow in other PICVs, the valve stroke is reduced. Since the Siemens pressure independent control valve is independent of the valve stroke, you achieve full control regardless of the maximum flow setting.
Higher Reliability
Every Siemens valve and actuator is tested right from the factory line to assure longer performance. Siemens goes above and beyond with rigorous lifecycle testing of up to 100K full strokes and up to 1 million repositions for higher reliability.
