This short animation shows the inside workings of an FJVA thermostatic water valve—part of Danfoss’s range of industrial temperature regulation components.

The FJVA self-regulates water flow depending on water temperature without the need for an auxiliary power source—ensuring no overconsumption of cooling water, hot water, or steam.

Product codes 003N8210, 003N8244, and 003N8245:

• Regulation range: 0–30 °C
• Media temperature: -25–55 °C
• Differential pressure: 0–10 bar

Product codes 003N8211, 003N8247, 003N8215, and 003N8216:

• Regulation range: 25–65 °C
• Media temperature: -25–90 °C
• Differential pressure: 0–10 bar

An FJVA valve is ideal for applications where a capillary tube isn’t suitable, and where there won't be any large and sudden load changes.
