Balancing valve for hot water ALWA kombi-4, DN32 V1810Y0032

Balancing valve for hot water – precision and reliability in every system

This Alwa Kombi-4 balancing valve, with a nominal diameter of DN32, is a key element in ensuring the optimal functioning of domestic hot water installations. Designed for both professional installers and users who appreciate comfort and efficiency, it combines throttling and shut-off and regulating functions. Made of high-quality dezincification-resistant brass (DZR), it guarantees long-lasting and trouble-free operation even in difficult conditions.

This valve works perfectly in systems with circulating hot water, allowing for precise hydraulic balancing of the installation. The ability to use it as a throttling valve with a preset setting or in combination with a thermal head allows it to be adapted to the individual needs of each system. This allows you to effectively regulate the flow and maintain a constant water temperature throughout the circuit.

Functionality and construction for demanding users

The Alwa Kombi-4 valve stands out with its well-thought-out design, which translates into ease of installation and operation. It has internal gas tapered BSPP-G (ISO 228-1) threads with a diameter of 32 mm, which ensures tight and durable connections. The position indicator makes it easy to read the current setting, and the hidden knob protects against accidental changes. In addition, the valve is compatible with actuators, which allows for automation of the regulation process.

It is worth paying attention to a number of structural features that affect the reliability of the device:

• Cavitation-free valve insert: Ensures smooth flow and minimizes the risk of damage.
• Stem seal: Made of PTFE, guarantees tightness and maintenance-free operation.
• DZR brass body: Corrosion resistant and ensures long life.
• Possibility of thermal disinfection: Without disrupting the hydraulic balance of the system.
• Drain function: Allows emptying and filling of installation risers.

Application and operating parameters

The Alwa Kombi-4 valve is designed to operate in domestic hot water installations with a temperature range of 2°C to 130°C and a working pressure of up to 16 bar. Its Kv value range is from 1.02 to 16, which allows for precise adjustment to different installation parameters. The possibility of mounting a thermal head expands the functionality of the valve, allowing you to maintain a constant water temperature and carry out thermal disinfection in accordance with DVGW W551 and W553 standards. The valve also meets the requirements of DVGW, WRAS and PZH standards, which confirms its high quality and safety of use. The manufacturer's warranty is as long as 5 years from the date of production!
