Danfoss AVTA 15 Thermostatic Water Regulating Valve | 1/2 in G | 003N0041
Product Description: The AVTA 15 (003N0041) is a “self-acting” valve, meaning it operates entirely without the need for electricity or compressed air. It modulates the flow of cooling water based on the temperature sensed by its remote bulb. In the UAE—where industrial equipment and hydraulic power packs are subject to high ambient heat—the AVTA 15 ensures that cooling water is used only when necessary, keeping the equipment at a constant temperature. The 1/2 inch G connection is the most common size for modular machinery imports in Dubai. Its robust brass construction is designed to handle the pressure and mineral content of industrial water supplies typical of the Middle Eastern region.
Key Features & Benefits:
- Self-Acting Operation: Requires no power supply, ensuring cooling continues even during electrical outages—a critical safety feature for UAE industrial plants.
- Precise Temperature Control: Modulates water flow proportionally to maintain the exact setpoint, improving the lifespan of hydraulic oils and mechanical seals.
- Pressure Relieved Design: The valve remains accurate regardless of fluctuations in the water supply pressure.
- Insensitive to Dirt: The internal design is less prone to clogging than solenoid valves, making it ideal for the industrial water conditions in the Emirates.
- Easy Installation: The compact design and G 1/2 threads allow for straightforward integration into existing cooling circuits.

FAQs:
- Q: Does this valve come with the sensor/bellows?
- A: This code typically refers to the valve body. AVTA valves require a thermostatic element (bellows and sensor) which is chosen based on the desired temperature range (e.g., 10–80°C).
- Q: Is it suitable for hydraulic oil cooling in Sharjah?
- A: Yes, it is the industry standard for maintaining hydraulic oil at the correct viscosity by regulating the cooling water flow.
- Q: Can it be used for heating applications?
- A: No, the AVTA is a “close-on-rising-temperature” valve designed primarily for cooling applications.
