Why Choose the Rittal SK 3301.940 Flow Regulator Valve?
The Rittal SK 3301.940 is a precision flow regulator valve for air/water heat exchangers, designed for volumetric flow control and hydraulic balancing within industrial cooling water circuits. It is particularly useful when more than one air/water heat exchanger is connected to the same cooling circuit and an even distribution of cooling medium is required.
Correct hydraulic balancing helps ensure that every connected heat exchanger receives the appropriate quantity of cooling medium. The SK 3301.940 provides an adjustable 3–12 l/min flow range with direct flow indication, allowing technicians to regulate water distribution efficiently and support consistent cooling performance across multiple pieces of equipment.
Manufactured from durable brass, the SK 3301.940 features a ¾″ × ¾″ connection configuration and a nominal size of DN 15. The valve has a Kvs value of 1.85 m³/h and is suitable for horizontal, vertical or inclined pipe installation, providing a flexible solution for industrial enclosure cooling circuits.

Reliable Hydraulic Balancing for Cooling Circuits
When several air/water heat exchangers operate on a common cooling water circuit, differences in hydraulic resistance can result in uneven water distribution. Some heat exchangers may receive excessive flow while others receive insufficient cooling medium, potentially reducing the efficiency and consistency of the overall enclosure climate control system.
The Rittal SK 3301.940 allows technicians to set the required water volume directly at the heat exchanger or subsystem. Its integrated flow indication and 3–12 l/min adjustment range simplify hydraulic balancing, helping provide consistent cooling-medium distribution and efficient operation across connected equipment.
Typical Applications
- Rittal air/water heat exchangers.
- Cooling circuits containing multiple air/water heat exchangers.
- Hydraulic balancing of industrial cooling systems.
- Industrial electrical enclosure climate control.
- Machine and automation cooling installations.
- Water-based thermal management systems requiring adjustable volumetric flow control.
