Three-way mixing valve Afriso ARV 385 ProClick DN32 RP1 1/4 with electric actuator ARM 343 ProClick

Three-way mixing valve Afriso ARV 385 ProClick DN32 RP1 1/4 with electric actuator ARM 343 ProClick is a factory-matched assembly for controlled blending of two hydraulic streams in heating and cooling circuits. The unit integrates a DN32 valve body with RP 1 1/4 threaded connections and a ProClick quick-fit coupling for the ARM 343 electric actuator. It is intended for modulating temperature control, return flow mixing and hydraulic balancing in residential and commercial installations where automated regulation is required.

Advantages

The ProClick connection enables tool-free mounting of the ARM 343 actuator, reducing installation time and ensuring consistent mechanical coupling. The DN32 valve size provides a balance between flow capacity and compact footprint suitable for mechanical rooms and plant cabinets. Combined valve and actuator control simplifies commissioning and integration with building management systems that support actuator control signals. The design supports bidirectional flow mixing and precise proportional adjustment for stable temperature regulation.

Suitable for

• Mixing supply and return water in heating circuits
• Modulating temperature control in radiant heating and fan-coil systems
• Hydraulic balancing and bypass control in boilers and heat pumps
• Retrofitting installations requiring an electric actuator with ProClick coupling

Key specifications

• Valve type: three-way mixing valve with modulating capability
• Connection type: ProClick quick coupling for actuator and RP 1 1/4 threaded pipe connections
• Nominal diameter: DN32
• Actuator: electric modulating actuator designed for direct mounting
• Application medium: water and water/glycol mixtures typical for HVAC systems
• Function: proportional mixing/blending of two flows for temperature control

How to use

Install the valve in the hydraulic circuit following flow direction markings and ensure RP 1 1/4 threaded connections are sealed and tightened to recommended torque. Mount the ARM 343 actuator onto the ProClick coupling until it locks into place; no special tools are required for that mechanical connection. Connect the actuator wiring to the control signal source according to the actuator electrical documentation and configure control parameters via the building management system or local controller. Commission the assembly by verifying stroke range, end positions and correct mixing behavior at operating temperatures before placing the system into normal operation.

Usage recommendations

Use corrosion-inhibited media and follow manufacturer guidelines for maximum fluid temperature and pressure. Periodically inspect the ProClick coupling and threaded connections for tightness and signs of wear. When integrating with control systems, verify actuator compatibility with control signal type (e.g., 0–10 V, 4–20 mA or PWM) and perform routine functional checks to maintain accurate temperature regulation.
