Three-way diverting valve DN15 bronze 4160-02.000

Professional three-way valve for heating and cooling systems

The DN15 switching three-way valve is a key component of heating and cooling installations, enabling precise control of medium flow in HVAC systems. Designed to redirect heating and cooling water, it provides a reliable solution for both professional installers and end users seeking efficient regulatory solutions.

Design and materials ensuring long-term operation

The valve body is made of corrosion-resistant bronze, which guarantees stable operation for many years of service in diverse environmental conditions. This material is characterized by natural resistance to moisture and chemical substances found in typical heating installations.

A key structural element is the double O-ring seal, which ensures connection tightness even during long-term operation under a working pressure of PN 10. A particular advantage is the ability to replace the external O-ring without the need to drain the installation, which significantly simplifies maintenance work and minimizes system downtime.

Operating parameters and hydraulic performance

The valve operates in a wide temperature range from 2°C to 120°C (up to 100°C when installed with an actuator), enabling its use in both traditional heating systems and modern cooling installations. A Kvs value of 2.47 guarantees optimal hydraulic performance while maintaining low flow resistance.

The maximum allowable differential pressure is 1.20 bar, allowing for safe operation in most typical HVAC installations without the risk of unwanted vibrations or hydraulic noise.

Versatility of application and system compatibility

The valve design allows it to be used as a traditional diverting valve or as a switching valve after installing a suitable servomotor actuator. This allows a single product to perform various regulatory functions depending on the needs of a specific installation.

The use of Heimeier thermostatic heads enables the achievement of intermediate control positions, providing more flexible control over temperature distribution in the medium distribution system.

The threaded connection with a nominal diameter of DN15 (1/2") and compatibility with various types of connections (threaded, brazed, or welded) allows for easy installation in existing systems without the need for comprehensive modernization.

The product's overall dimensions (weight only 0.26 kg) and compact design ensure it occupies minimal installation space, which is particularly important when modernizing space-constrained technical rooms or boiler rooms.

High manufacturing quality and reliable operation over a long service life eliminate the need for costly repairs or the replacement of prematurely worn components.
