Combination fitting 3-Plus blue, return, 1/2 inch, female thread V5010Y0015

The Kombi-3-Plus regulating valve in blue is an element used for precise control of hot water flow in central heating systems. Designed for mounting on return lines and branches, it enables effective hydraulic balancing of the heating system. It works with V5000 Kombi-3-plus valves (red) mounted on the supply side, creating a complete static regulation system.

The construction based on dezincification-resistant brass (DZR) ensures durability and reliability even in harsh working conditions. The valve has internal gas BSPP-G (ISO 228-1) threads with a diameter of 1/2 inch, which facilitates integration with the existing installation. The Kvs value of 2.7 allows for precise flow adjustment, and the Kv value range from 0.37 to 2.7 provides great flexibility in system configuration.

This model is distinguished by the possibility of sealing/locking the initial settings, which prevents accidental changes and guarantees stable operation. Additionally, the presence of a drain simplifies maintenance and allows for safe emptying of parts of the installation. The position indicator allows for quick visual control of the valve status, and the possibility of expansion to an automatic version – through cooperation with an actuator – opens the way to modernization and optimization of the heating system. The valve is adapted to work with DHW and withstands a working pressure of up to 16 bar in a temperature range of -20 to 130°C. The stem angle is 45 degrees, which affects the convenience of adjustment.

• Durability and reliability: Made of dezincification-resistant brass (DZR).
• Precise regulation: Kvs value of 2.7 and Kv range of 0.37…2.7 ensure accurate adjustment of hot water flow.
• Safety: The ability to seal the initial settings protects against accidental changes.
• Flexibility: Possibility of expansion to an automatic version with an actuator.
• Ease of use: Position indicator facilitates control of the valve status and the presence of a drain simplifies maintenance.
• Compatibility: Designed to work with V5000 Kombi-3-plus valves (red).

This valve finds application both in new central heating installations and during the modernization of existing systems, where precise flow regulation and hydraulic balancing of heating circuits are required. It is ideal for installers looking for a reliable and easy-to-install solution, and for end-users who want to increase thermal comfort and reduce heating costs.
