Rotary mixing valve 3-way ARV 385 Vario ProClick, DN32, Rp1 1/4 inch Kvs=7.5-19 1338520

Rotary mixing valve – precise temperature control in the installation

This 3-way rotary mixing valve ARV 385 Vario ProClick, with a nominal diameter of 1 1/4 inch (DN32), is a reliable solution for temperature control in heating and cooling systems. Designed to mix streams of heating or cooling medium, it allows you to obtain the required supply temperature, which translates into user comfort and energy efficiency. The valve is perfect for both new installations and for modernizing existing systems.

Design and application – versatility in practice

The ARV 385 valve finds wide application as a mixing element on the supply side of the installation, but can also function as a diverting or switching valve. Its construction based on dezincification resistant brass (DZR) guarantees durability and corrosion resistance. Precise flow control is possible thanks to a wide range of Kvs values of 7.5-19, which allows you to adapt the valve to different installation parameters and heat sources – including heat pumps. Low internal leakage (0.3% for Kvs value and 0.05% for bypass) ensures stable system operation.

ProClick and Vario – innovative solutions for installers

The valve is equipped with the ProClick system, which allows direct mounting of the actuator without tools – significantly reducing installation time and minimizing the risk of errors. The Vario function allows you to change the Kvs setting using a lever, making it easier to adapt the valve to specific operating conditions. A clear two-sided scale with an indicator of the current valve position further increases comfort and precision of regulation. Octagonal connections facilitate installation in tight spaces. The maximum differential pressure in the open position is 12 bar.
