Pressure independent control valves from Siemens integrate control, flow limiting, and automatic differential pressure regulation in one device to optimize delta‑T and deliver precise, stable comfort with faster commissioning.
PICVs maintain constant flow despite pressure swings, improving heat transfer through coils which maximizes delta‑T and reduces HVAC energy consumption across hydronic systems.
Preset maximum flow and self‑balancing behavior cut components and manual balancing effort, enabling faster commissioning and future system changes without rebalancing.
Integrated differential pressure regulation eliminates actuator hunting and stabilizes zone temperatures for consistent occupant comfort in variable flow systems.
Built‑in mechanical differential pressure regulation holds the selected flow across the working range, shielding terminal units from network pressure fluctuations.
A ring‑dial preset lets you set and verify the maximum volumetric flow on site, supporting rapid, repeatable commissioning and performance validation.
PICVs integrate with SSD and SAY for threaded bodies and SAX, SAV, SQV for flanged bodies, offering floating or modulating signals and direct‑coupled installation.
