Mixing rotary valve Afriso ARV 485 ProClick DN32 Rp1 1/4 Kvs 18A — 4-way

Afriso ARV 485 ProClick DN32 Rp1 1/4 Kvs 18A is a 4-way rotary mixing valve engineered for hydraulic heating and cooling systems. It combines a DN32 nominal diameter with a Rp1 1/4 threaded connection and a Kvs 18A flow characteristic to provide precise control of mixed supply and return flows. The valve is suitable for integrating with actuators and system controls to stabilise circuit temperatures and support system balancing in residential and light-commercial installations.

Advantages

The 4-way rotary design enables reliable blending of two supply streams to achieve a target outlet temperature while minimising pressure losses. ProClick connection features ensure straightforward installation and secure sealing with compatible threaded fittings. The valve’s Kvs 18A rating offers predictable flow behaviour for hydraulic calculations, and its DN32 size supports medium-capacity circuits without the need for adapters. Construction materials and internal geometry are optimised for long service life and stable operation under typical heating and cooling loads.

Suitable for

• Temperature control in heating circuits and chilled water loops
• Hydraulic balancing of multi-zone residential systems
• Integration with electric or pneumatic actuators for automatic control
• Applications requiring a 4-way mixing arrangement to shift or blend flow paths

Key specifications

• Nominal diameter: DN32
• Connection type: Rp 1 1/4 threaded
• Flow coefficient: Kvs 18A
• Valve type: 4-way rotary mixing valve
• Suitable media: water and water-glycol mixtures typical for HVAC systems

How to use

Install the mixing valve in the hydraulic circuit ensuring correct orientation of the inlet and outlet ports according to the system design. Connect the Rp1 1/4 threaded fittings using appropriate sealing methods compatible with the ProClick interface. Integrate an actuator matched to the valve’s drive interface to enable automated position control. Commission the system by checking for leaks, verifying flow directions and performing hydraulic balancing. Adjust actuator travel or controller settings to obtain the required mixed outlet temperature and confirm stable operation under normal load conditions.

Usage recommendations

Use antifreeze-compatible fluids if glycol mixtures are present, and follow manufacturer guidance for actuator compatibility and torque limits. Periodically inspect threaded connections and the valve body for signs of wear or leakage, and include the valve in routine system maintenance to preserve performance.
