Rotary mixing valve 3-way ARV 387 Vario ProClick, DN50, Rp 2 inch Kvs=17-50 1338720

The ARV 387 Vario ProClick mixing valve is a reliable solution for precise temperature control in heating and cooling systems. This 3-way valve, made of dezincification-resistant brass (DZR), is perfect for both new and modernized systems. Its versatility stems from its ability to function as a mixing, diverting, and switching valve.

Construction and application

The ARV 387 Vario ProClick valve is characterized by a nominal diameter of DN50 (2 inches) and a Kvs flow rate adjustable in the range of 17-50. This means it can be adapted to different flows and installation needs. The square flow characteristic ensures stable operation over a wide load range. Rp 2 inch threaded connections facilitate installation, and the hexagonal connection shapes further increase convenience during installation. The valve is designed to operate at temperatures from 5 to 95°C and withstand a differential pressure of up to 14 bar.

Functionality and benefits

The ProClick system is a key feature of this valve – it allows direct actuator mounting without the use of additional tools, which significantly speeds up and simplifies installation. The Vario function allows changing the Kvs setting using a lever, providing full control over the flow of heating or cooling medium. A clear two-sided scale (L/R from 0 to 10) and a valve position indicator allow for precise setting of the desired temperature. Low leakage (0.7% for Kvs value and 0.2% for bypass) guarantees efficient system operation and minimizes energy losses. The brass construction ensures durability and corrosion resistance, and the appropriate design allows for a distributive type of installation.
