PICV Valves
Optimize Delta T by Maintaining Constant Flow
Resources
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.
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.
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).
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 & 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, 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.
