AB-QM 4.0 Pressure Independent Control Valves (PICVs) are the successor of Danfoss AB-QM. They offer best-in-class specifications and easy installation. The scaling- and clogging resistant design secures and outstanding reliability and long lifetime.

Feb 27, 2020 · Pressure independent control valves will often be abbreviated to the letters PICV. This is a type of valve found in Hydronic systems, meaning water based, which provide heating and cooling in buildings.

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.

Pressure Independent Control Valves (PICV) can help reduce energy costs and increase occupant comfort in heating and cooling coil applications in buildings. A PICV is best described as two valves in one: a standard 2-way control valve and a balancing valve.

A compact one-unit PICV with a modulating control valve, dynamic flow limiter and differential pressure control valve in one body – these exciting features make the pressure independent control valve work in both heating and cooling systems.

Dec 12, 2024 · Pressure Independent Control Valves (PICVs) offer several advantages over traditional balancing valves. Firstly, PICVs maintain a constant flow rate regardless of system pressure fluctuations, ensuring stable operation and precise temperature control.

May 10, 2023 · Pressure Independent Control Valves (PICVs) regulate the flow of fluid in HVAC systems, independent of pressure fluctuations in the system. They combine the functions of a control valve, a pressure regulating valve, and a flow limiter into a single device.

When equipped with a Danfoss actuator, PICVs increase the energy efficiency and improve the indoor climate. The AB-QM is mainly used for air handling units, climate ceilings, fan-coil units and other terminal units in HVAC heating and cooling systems. Easy setting and sizing.

PICV valves can be used in either 2-pipe direct return distribution systems or 2-pipe reverse return distribution systems. They provide the functional equivalent of either a zone valve paired with an automatic balancing valve, or a static balancing valve paired with a …

Honeywell pressure independent control valve (PICV) is used in heating and cooling systems in applications with Air Handling Units, Fan Coil Units, chilled ceilings, zone control, or other terminal unit applications.
