## Long description

Afriso AZV 642 G3/4'' switching – hydraulic zone control valve is a 3-way switching valve designed for reliable routing of heating and cooling media in hydronic systems. With G3/4'' threaded connections and a compact brass body, this valve enables changeover between two flow paths to manage circulation to radiator or underfloor heating zones. Intended for use with compatible actuators and controllers, the AZV 642 helps balance individual zones, reduce pumping losses and simplify commissioning and maintenance of multi-zone systems.
Advantages
The valve provides stable and accurate switching between flow paths and is compatible with standard actuator interfaces, allowing automated zone control. Its construction ensures tight shutoff and low internal leakage, supporting efficient system operation. The compact design and standard G3/4'' connections make installation straightforward in existing and new installations. The device is service-friendly, offering easy access for inspection and replacement when paired with removable actuators.
Suitable for
Switching between flow circuits in radiator heating systems
Controlling supply to underfloor heating zones
Hydronic changeover applications in mixed heating/cooling systems
Integration with zone controllers and thermal actuators
Key specifications
Valve type: 3-way switching valve for hydraulic zone control
Connection size: G3/4'' threaded connections
Body material: corrosion-resistant brass (compact design)
Operation: designed for use with electric or thermal actuators (separate)
Application: heating and cooling hydronic systems, zone balancing
Mounting: in-line installation with standard plumbing fittings
How to use
Install the valve in the piping run according to flow direction markings and secure using appropriate G3/4'' fittings and sealing. Mount a compatible actuator onto the valve drive spindle following the actuator manufacturer instructions and connect to the zone controller. Commission the system by checking for leaks, ensuring correct actuator travel and verifying that the valve switches cleanly between the two flow paths under controller commands. Regular visual inspection and periodic actuator function checks are recommended to maintain reliable operation.
Usage recommendations
Use the valve with actuators specified for 3-way switching operation and ensure system water quality meets common hydronic standards to avoid premature wear. During installation, flush the system to remove debris and fit strainers where appropriate. If used in mixed heating/cooling systems, verify compatibility of actuator control signals with the zone controller to ensure correct switching behavior.
