Description
The Danfoss 003N-7272RA is a 3/4″ self-acting temperature regulator engineered for reliable, automatic temperature control in hydronic heating systems, industrial process piping, and HVAC applications. Operating on an open-on-rise principle, this regulator opens the valve as the sensed temperature increases, providing intuitive and dependable modulation without the need for external power or control signals.
Key Features
- 3/4″ connection size for straightforward inline installation
- Temperature control range: 122°F to 194°F (50°C to 90°C)
- Open on Rise (ORise) action — valve opens as temperature increases
- Self-acting, self-contained design — no external power source required
- Danfoss precision engineering for consistent, long-term performance
- Suitable for hydronic heating, district energy, and process temperature control applications
How It Works
The 003N-7272RA uses a thermostatic element filled with a temperature-sensitive medium. As the fluid temperature rises within the set range, the element expands and opens the valve, allowing flow to increase and moderate system temperature. This self-regulating action ensures stable control without electronic components or external energy input.
Typical Applications
- Hydronic heating and district heating systems
- Heat exchanger temperature regulation
- Industrial process fluid control
- Domestic hot water and boiler circuits
