Combination valve 2-Plus, return, with low flow, 1/2 inch female thread V5032Y0015BLF

The Kombi 2-Plus regulating and measuring valve is a reliable solution for precise flow control in central heating systems. Designed for installation on the return line, it combines regulation, measurement, shut-off, filling, and draining functions for a heating zone. Made of high-quality dezincification-resistant brass (DZR), it ensures durability and corrosion resistance.

This valve is particularly useful in systems with variable and constant flow rates, allowing for manual hydraulic balancing. It features a position indicator for easy reading of the setting, and SafeCon measuring ports provide quick and easy flow measurement. This ensures that both installers and end-users can be confident in the proper operation of the heating system.

Features and application

Kombi 2-Plus is characterized by its versatility and ease of use. Its design allows it to work with the Kombi Dp diaphragm regulator and V5000 Kombi-3-plus valves, creating a comprehensive regulation system. The ability to seal the initial setting protects against unauthorized changes. The valve is designed to work with water and water-glycol mixtures (up to 50%), in a temperature range of -20°C to 130°C and a working pressure of up to 16 bar. The Kvs value is 0.43, making it ideal for applications requiring precise flow control in installations with a nominal diameter of DN15 (1/2 inch).

• Hydraulic balancing: Static, ensuring stable operating parameters of the heating system.
• Shut-off function: Allows isolation of a section of the installation without the need for disassembly.
• Flow measurement: Integrated measuring ports facilitate diagnostics and optimization of system operation.
• Durability: DZR brass construction guarantees corrosion resistance and long life.
• Safety: The ability to seal the initial setting prevents accidental changes by users.
• Easy installation: Standard BSPP-G (ISO 228-1) internal gas tapered thread facilitates integration with existing installations.

Design and parameters

The Kombi 2-Plus valve has been designed for reliability and functionality. The body is made of brass, and the insert made of brass with a PTFE seal ensures tightness and smooth operation. The height of the actuator is 82 mm, and the nominal diameter is DN15 (1/2 inch). The valve has a stem angle of 45 degrees, which facilitates its installation in tight spaces. The connection length is 32.5 mm on both side 1 and side 2. The use of SafeCon measuring ports enables precise measurement of the pressure difference, which is crucial for the correct operation of the regulation system. The manufacturer's warranty is as long as 5 years from the date of manufacture!
