4-way rotary mixing valve Afriso ARV 484 ProClick DN25 Rp1 Kvs 9 m3/h

The 4-way rotary mixing valve Afriso ARV 484 ProClick DN25 Rp1 Kvs 9 m3/h is a compact hydraulic component designed for precise temperature control and proportional flow distribution in heating and cooling circuits. Intended for installation in HVAC systems, this valve routes and mixes return and supply flows to stabilise system temperatures. Its rotary spindle operation enables smooth modulation of flow between ports, making it suitable for boiler return regulation, zone mixing and system balancing where reliable, space-saving mixing is required.

Advantages

The Afriso ARV 484 ProClick offers proportional flow control with a compact DN25 body that fits installations with Rp1 threaded connections. Its rotary design provides reliable and repeatable modulation across the stated flow rating, ensuring stable hydraulic behaviour in mixed circuits. The valve's construction supports straightforward integration into existing systems and reduces the need for larger assemblies by combining mixing and diverting functions in a single unit.

Suitable for

• Hydronic heating systems requiring temperature mixing and return regulation
• Cooling circuits where proportional flow distribution is needed
• Boiler return temperature control to prevent thermal shock
• Zone control and balancing in multi-circuit HVAC installations

Key specifications

• Valve type: 4-way rotary mixing valve with ProClick operation
• Nominal size: DN25
• Connection: Rp1 threaded ports
• Flow coefficient: Kvs 9 m3/h
• Function: Proportional flow distribution and mixing between ports

How to use

Install the valve in the piping layout following the required flow direction so that mixing and diverting functions operate correctly. Connect the port threads to compatible Rp1 fittings and ensure all joints are sealed and pressure-tested according to system standards. Use the rotary spindle to set the desired mixing ratio; fine adjustments allow proportional control of temperature and flow. When commissioning, verify hydraulic balance and temperature response across operating ranges.

Usage recommendations

For reliable operation, ensure compatibility with system media and temperatures, perform pressure testing after installation, and follow local codes for HVAC hydraulic systems. Regular inspection during routine maintenance helps detect wear or leaks and maintains accurate mixing performance.
