Combination unit 3-Plus red, supply connection, 1 inch, BSPP 1 inch V5000Y0025

Shut-off valve with flow rate and pressure drop measurement

This red shut-off valve, with a nominal diameter of DN25 (1 inch), is a key component in heating and cooling systems. Designed to work with other automatic regulation components, such as balancing valves and diaphragm regulators, it enables precise control of the flow of heating or cooling medium. Its construction allows for measuring both flow rate and pressure drop in the installation, which is essential for proper hydraulic balancing.

The Kombi 3-Plus valve performs a shut-off function, also allowing filling and draining of installation risers. Made of dezincification resistant brass (DZR), it guarantees durability and reliability even in harsh operating conditions. The maximum working pressure is 16 bar, and the operating temperature range reaches from -20°C to 130°C, making it a universal solution for various applications. Thanks to the possibility of sealing the initial settings, it ensures safety and stability of the system operation.

Construction features and application:

• Wide range of applications: Ideal for water heating and cooling installations.
• 3-in-1 function: Cuts off flow, enables measurement and filling/draining of the installation.
• Material: Made of dezincification resistant brass (DZR) – provides long-term protection against corrosion and high strength parameters.
• Connections: Has internal gas parallel threads BSPP-G (ISO 228-1) with a size of 1 inch, which facilitates integration with existing infrastructure.
• Kvs value: 6.5 – a parameter determining the valve flow capacity, important when selecting the appropriate element for a specific system.
• Hydraulic balancing: Allows precise adjustment of flows in individual circuits of the installation, eliminating problems related to uneven distribution of heat or cold.
• Application in Heating Systems: Designed for operation in central heating systems.
• Possibility of sealing: Protects against unauthorized changes to the initial settings.

This valve is particularly useful during the modernization of existing installations, where precise adjustment of operating parameters is crucial for energy efficiency and user comfort. Thanks to its construction and functionality, it is a reliable solution for both professional installers and end-users looking for an effective way to control their heating or cooling system. This is an additional argument for choosing this product.
