Pressure Independent Control Valve

Pressure Independent Control Valves (PICV)

Shop all Pressure Independent Control Valves at iACS. A picv valve is a critical component in modern HVAC systems, designed to maintain a constant flow rate regardless of pressure fluctuations within the system. Utilising a picv valve simplifies the balancing process and prevents overflows, which significantly reduces pumping costs. You can read our detailed article on how the valve works in the AHU systems and HVAC control valves.

If you require assistance selecting the correct DN size or flow rate for your project, please Contact Us today. Browse the full range at iACS.

IACS supplies all of the PICVs made by Belimo, Siemens, and Danfoss.

In HVAC, a PICV is a type of valve that may vary the rate of flow at various pressure levels in the HVAC system where it is mounted. The pressure has no effect on the operation of the PICV valve. Contact our IACS support team for technical advice.

How a pressure independent control valve works

The function of a Pressure Independent Control valve is to keep a constant flow rate independently of system pressure variations. Explore all sorts of control valves in HVAC in this article on the IACS blog.
