ProClick regulating set: 3-way rotating mixing valve ARV 387 Vario ProClick, DN50, Rp 2 inch, Kvs 17 - 50 m3/h + electric actuator ARM 343 ProClick 1338754

Temperature control in heating and cooling systems – mixing valve set with actuator

This ProClick control set combines precision and convenient installation. It consists of a 3-way rotating mixing valve ARV 387 Vario ProClick with a diameter of DN50 (2 inches) and an electric actuator ARM 343 ProClick. This set is an ideal solution for installers and users looking for a reliable way to control temperature in heating and cooling systems. The valve, thanks to the ability to regulate flow, allows for precise mixing of fluid streams, ensuring optimal temperature in the circuit.

Functionality and application

The ARV Vario ProClick valve is widely used in heating and cooling systems, especially as a mixing element on the supply side. Its design allows not only mixing but also dividing and switching fluid streams. The ARM 343 ProClick electric actuator provides automatic control, cooperating with an external three-point controller. This solution is particularly useful in systems requiring precise temperature control without manual intervention.

ProClick – speed and installation convenience

The key feature of this set is the ProClick system, which allows direct mounting of the actuator onto the valve – without the need for additional tools. This significantly reduces installation time and simplifies the service process. Additionally, the valve is equipped with a Vario function, allowing the Kvs coefficient to be changed in the range of 17 to 50 m³/h using a dedicated lever. This makes it easy to adapt the flow to the specific needs of the installation. A clear bilateral scale (L/R) facilitates reading the current valve position, and octagonal connections ensure convenient installation.

Technical characteristics and materials

The valve is made of dezincification resistant brass (DZR), which guarantees its durability and corrosion resistance. The actuator operates at 230 V AC and is characterized by low power consumption – only 4 VA. The maximum differential pressure in the open position is 10 bar, and the operating temperature range is 5-95°C for heating/cooling medium and 0-50°C for the environment. Valve leakage is only 0.7% of the Kvs value, which confirms its high quality and reliable operation. The IP42 protection class provides resistance to the ingress of solid objects larger than 1mm and splashing water.
