Product information

Description

The Rittal 3301940 balancing valve is designed for use in air-to-water heat exchanger circuits, ensuring equal flow distribution when multiple heat exchangers are connected in the same water cooling loop. It is a compact mechanical valve suitable for installation in chilled-water systems to stabilise coolant flow to each exchanger.

Advantages

The valve provides accurate hydraulic balancing when more than one heat exchanger is used, helping to maintain uniform cooling performance across multiple units. Its compact, lightweight construction allows straightforward installation in existing water cooling circuits and reduces the need for repeated manual adjustments.

Suitable for

Air/water heat exchangers in data center or electronic cooling applications
Water cooling circuits with two or more heat exchangers
Retrofit installations where equalised flow to each exchanger is required

When it may not be suitable

This valve is intended specifically for hydraulic balancing in chilled-water air/water heat exchanger systems; it is not a general-purpose control valve for complex proportional flow control or for use with aggressive fluids. For single-exchanger systems or applications requiring active electronic flow control, a different component may be more appropriate.

Key specifications

Connection size: 3/4" x 3 (as specified for compatibility with standard exchanger ports)
Application: hydraulic balancing in water cooling circuits with multiple heat exchangers
Weight: approximately 180 g

How to use

Install the balancing valve in the supply or return line to each air/water heat exchanger following system piping practices and manufacturer installation guidelines. Adjust the valve setting so that the flow rate through each exchanger matches the desired value; this may be verified using flow meters or by measuring temperature differentials across exchangers. After setting, secure the valve position to prevent unintentional changes.

What to consider before purchase

Ensure the valve connection size and thread type match your heat exchanger plumbing
Confirm the valve's suitability for the coolant used (water or water-glycol mixtures)
Evaluate whether passive hydraulic balancing meets your system control requirements

Usage recommendations

Use the balancing valve as part of a planned commissioning process: measure baseline flows, adjust each valve to achieve uniform distribution, and document final settings to simplify future maintenance or troubleshooting.
