ProClick regulating set: 3-way rotating mixing valve ARV 385 Vario ProClick, DN32, Rp1 1/4 inch, Kvs 7.5 - 19 m3/h + electric actuator ARM 343 ProClick 1338554

3-way mixing valve with actuator – precise regulation in heating and cooling systems

This regulating set, consisting of a 3-way rotating mixing valve ARV 385 Vario ProClick and an electric actuator ARM 343 ProClick, is a reliable solution for precise temperature control in heating and cooling systems. Designed for both professional installers and end-users, it provides efficient mixing of fluid streams to achieve optimal temperature. The valve is perfect as an element of the supply installation, and can also function as a diverting or switching valve.

Construction and functionality

The set is distinguished by a solid construction based on dezincification-resistant brass (DZR), which guarantees long-lasting and trouble-free operation even in difficult conditions. The nominal diameter of the valve is 1 1/4 inch (DN32), and its flow rate (Kvs) ranges from 7.5 to 19 m³/h, allowing it to be adapted to various installation needs. Connections with an internal gas cylindrical BSPP-G thread (ISO 228-1) facilitate installation.

Particular attention is paid to the ProClick system, which allows direct mounting of the actuator onto the valve without the need for additional tools – this significantly speeds up installation work and saves time. The Vario function allows changing the Kvs setting using a lever, which increases the flexibility of the system. A clear two-sided scale makes it easy to precisely set the desired flow. Additionally, an indicator of the current valve position provides full control over the regulation process.

Advantages and technical parameters

• Quick installation: The ProClick system eliminates the need for tools when mounting the actuator.
• Flexibility: The Vario function allows changing the Kvs, adapting the valve to different working conditions.
• Precision: A clear scale and position indicator ensure accurate temperature regulation.
• Durability: Made of dezincification-resistant brass, guaranteeing a long service life.
• Wide range of applications: Ideal for heating and cooling installations as a mixing, diverting or switching valve.
• Supply voltage: 230 V AC – standard mains voltage facilitates integration with existing infrastructure.
• Control signal: Three-point – ensures compatibility with most control systems.
• Protection class: IP42 – protection against solid objects larger than 1 mm and dripping water.
• Maximum differential pressure: 10 bar – safe operation under typical installation conditions.
• Leakage: Low leakage (0.3% for Kvs value) ensures minimal working fluid loss.
