## Long description

DANFOSS balancing valve 1 1/4" model 003L7614 (DWZ) is a hydraulic balancing valve designed for use in heating and cooling distribution systems. It provides accurate flow regulation and hydraulic balance in pipe networks, enabling precise adjustment of flow rates during system commissioning and operation. The valve is intended for integration with radiators, manifolds and HVAC circuits where stable flow and even distribution of heating or cooling medium is required.
Advantages
The balancing valve offers stable and repeatable flow control across a wide range of flow rates, helping to reduce temperature deviations and improve system efficiency. It supports precise differential pressure-independent or pressure-dependent adjustment depending on installation, simplifying commissioning and ensuring predictable hydraulic performance. The valve construction is suitable for professional plumbing and HVAC installations and is compatible with standard 1 1/4" pipe connections.
Suitable for
 Balancing radiator circuits in central heating systems
 Flow regulation on distribution manifolds for underfloor heating and multi-loop systems
 Hydraulic balancing of HVAC circuits in commercial and residential buildings
 System commissioning and fine-tuning of flow rates during maintenance
Key specifications
 Nominal connection size: 1 1/4"
 Function: hydraulic flow balancing and regulation
 Application: heating and cooling distribution networks
 Compatibility: designed for integration with radiators, manifolds and HVAC circuits
 Adjustment: precise flow rate setting for commissioning and maintenance
How to use
Install the balancing valve in the appropriate section of the distribution network following the system design and piping orientation. Use the valve adjustment mechanism to set the required flow rate or to achieve the target differential pressure as specified by the hydraulic design. During commissioning, progressively adjust valves across the system to obtain the intended flow distribution; record set positions if ongoing maintenance or future recalibration is anticipated. Verify tightness and correct operation after installation.
Usage recommendations
For accurate balancing, perform commissioning with measured flow or pressure-drop data and follow manufacturer guidance for permitted operating pressures and temperatures. Regular inspection and occasional recalibration ensure continued hydraulic performance; avoid exposure to aggressive fluids or uncontrolled freezing conditions.
