Danfoss 003N7182 Valve

The Danfoss 003N7182 is a heavy-duty AVTA 20 thermostatic water valve designed for professional contractors managing cooling systems and industrial heat exchange processes. Engineered with a rugged brass body and a 3/4-14 NPT connection, this valve provides self-acting flow regulation without the need for external power. It utilizes a universal charge sensor with a 78-inch capillary tube, specifically calibrated for a temperature range of 122°F to 194°F (50°C to 90°C). The internal mechanism is configured to open on rising sensor temperature, delivering a Cv value of 3.9 gal/min. With a maximum working pressure of 232 psi and a differential pressure range of 0 to 145 psi, this thermo-operated water valve ensures stable performance even in demanding hydraulic circuits. It is highly compatible with neutral media and is a standard component for Danfoss cooling water regulators in commercial HVAC and process cooling applications.

• Precision Temperature Control: The self-acting design ensures accurate Danfoss 003N7182 flow adjustments based on real-time sensor feedback, optimizing cooling efficiency.
• Industrial Durability: Forged brass construction and EAC, RoHS, and PED certifications guarantee reliability in high-pressure industrial environments.
• Flexible Installation: Features a 78-inch (2-meter) capillary length for versatile sensor placement away from the valve body.
• Balanced Flow Dynamics: A Kv value of 3.4 m³/h provides the necessary throughput for mid-sized heat exchangers and jacket cooling systems.
• High Thermal Tolerance: Rated for medium temperatures from -13°F to 266°F, making it suitable for both chilled water and high-temperature condensate applications.

What is the primary application for the AVTA 20 003N7182?
This thermostatic cooling water valve is typically installed in oil cooling systems, plastic injection molding machines, and industrial compressors to maintain constant discharge temperatures.

Does this valve require an external controller?
No, the Danfoss 003N7182 is a self-acting thermostatically operated valve. It functions autonomously based on the pressure exerted by the temperature-sensitive charge in the capillary sensor.

What media is compatible with this valve?
It is designed for use with neutral media, such as fresh water or neutral brine, ensuring the brass valve body remains resistant to internal corrosion.
