The Danfoss AVTA 20 thermally operated water valve is designed for the automatic regulation of water flow or neutral media depending on the sensor temperature. Thanks to its design, it requires no power supply — it operates purely mechanically based on pressure changes in the capillary. The valve opens as the sensor temperature increases, allowing for efficient temperature control across a wide range of applications.

Typical areas of use include industrial and technological processes, cooling systems, hydraulic circuits, heat exchangers, sterilizers, injection moulding machines, printing presses, and food processing equipment. The AVTA valve ensures a constant temperature without unnecessary energy waste, thereby increasing the efficiency of the entire system.
