DHW regulating valve Alwa-Kombi-4, female thread, 3/4 inch V1810Y0020

Domestic hot water regulating valve – precision and reliability in every system

The Alwa-Kombi-4 valve is an indispensable element of domestic hot water installations, designed for precise flow control and hydraulic balancing in circulation systems. Made of high-quality dezincification-resistant brass (DZR), it guarantees long-lasting and trouble-free operation even in harsh conditions. Its versatility makes it ideal for both professional installers and end-users looking for effective solutions.

This valve can operate as a pre-set throttling valve, providing static flow regulation. Additionally, the possibility of mounting a thermal head transforms it into a dynamic temperature regulator, maintaining a constant temperature level in the installation. This is particularly important in systems requiring thermal disinfection, where the valve retains its regulating and balancing properties. It is worth mentioning the possibility of draining and filling the riser using a dedicated drain cap – a function that facilitates servicing and maintenance of the installation.

Design and functionality for professionals:

The Alwa-Kombi-4 valve stands out with its well-thought-out design, which translates into ease of installation and use. A visible digital setting indicator with a hidden knob ensures precise flow adjustment, and high accuracy of factory calibration guarantees stable operating parameters. The cavitation-free valve insert with a maintenance-free stem seal eliminates the risk of failure and extends the life of the device. The stem thread isolated from the medium ensures safe use. Thanks to this, the valve does not require frequent inspections and maintenance, which translates into saving time and costs.

Benefits for the end-user:

• Thermal comfort: Stable water temperature at every draw-off point ensures comfortable use.
• Energy saving: Precise flow control minimizes heat loss and reduces system operating costs.
• Safety: The possibility of thermal disinfection eliminates the risk of Legionella bacteria developing in the installation.
• Durability: Made of high-quality materials guarantees long-lasting and trouble-free operation.
• Ease of use: An intuitive setting system allows you to independently adjust the valve's operating parameters to individual needs.

The Alwa-Kombi-4 valve is characterized by a maximum working pressure of 16 bar and an average operating temperature of 2 to 130°C, making it suitable for most standard DHW installations. The Kvs value of 6.4 ensures optimal flow with minimal pressure loss. It has numerous certificates (DVGW, WRAS, PZH) and is tested in accordance with KTW guidelines, confirming its high quality and compliance with applicable standards. The manufacturer's warranty is 5 years from the date of manufacture – this is additional proof of its reliability and durability.
