Danfoss AVTA Thermostatic Water Valve
Reliable self-acting thermostatic water regulation for refrigeration, water-cooled condensers and industrial cooling applications. Available in AVTA10, AVTA15, AVTA20 and AVTA25 with Universal, Mass and Adsorption charge options.
No Electrical Power Required Self-Acting Control G3/8″ – G1″ AVTA10 – AVTA25What is a Danfoss AVTA Thermostatic Water Valve?
The Danfoss AVTA thermostatically operated water valve automatically regulates water flow according to the temperature detected by its remote sensor.
As the sensor temperature rises, the valve progressively opens and increases cooling-water flow. This makes the AVTA particularly suitable for refrigeration equipment, water-cooled condensers, compressors and industrial processes where stable temperature regulation is required.
Key Features & Benefits
Choose the Correct AVTA Charge Type
🔵 Universal Charge
The most versatile AVTA charge option with several available temperature ranges.
Typical ranges:0 – 30°C
25 – 65°C
50 – 90°C
Sensor size approximately Ø18 × 210 mm. The sensor may be installed where it is warmer or colder than the valve body.
⚡ Mass Charge
Designed with a compact sensor and short response time, making it suitable where quick temperature response is desirable.
Typical range:25 – 65°C
Sensor size approximately Ø9.5 × 180 mm. The sensor should be installed in an area warmer than the valve body.
🟦 Adsorption Charge
Provides a wide regulating range together with a compact sensor.
Typical range:10 – 80°C
Sensor size approximately Ø9.5 × 150 mm and offers flexible installation regarding sensor orientation and temperature.

General Technical Specifications
Typical Applications
How Does the AVTA Water Valve Work?
1. Sensor detects temperature → The remote bulb continuously senses the equipment or process temperature.
2. Temperature increases → Pressure inside the thermostatic element changes.
3. AVTA valve opens → Additional cooling water is allowed to pass through the valve.
4. Temperature decreases → The valve automatically reduces the cooling-water flow.
Quick Model Selection Guide
Final valve selection should also consider required water flow, temperature regulating range, charge type, pressure conditions and application requirements.
