Danfoss RDT-N Thermostatic Radiator Valve DN20 Angle Pattern

The Danfoss RDT-N thermostatic radiator valve in the DN20 angle pattern is a professional-grade component engineered for precise temperature regulation in hydronic heating systems. This valve facilitates optimal thermal comfort by allowing users to control the flow of hot water into radiators with high accuracy. Its robust construction ensures long-term reliability and consistent performance in both residential and commercial heating infrastructures.

Advantages

This valve stands out due to its integrated pre-setting function, which is essential for achieving accurate hydraulic balancing across a heating network. By ensuring that each radiator receives the correct amount of water flow, the system operates more efficiently, which contributes to significant energy savings and reduced operational costs. The angle-pattern design provides flexibility during installation, particularly in tight spaces where pipework requires a 90-degree turn to connect to the radiator.

Suitable for

• Residential central heating systems
• Commercial building radiator installations
• Hydronic heating networks requiring hydraulic balancing
• Replacement of standard manual radiator valves

When it may not be suitable

This valve is not intended for use in steam heating systems or high-pressure industrial process piping. It is specifically designed for water-based central heating applications and may not be compatible with non-standard radiator connections or systems using aggressive chemical additives.

Key specifications

• Connection size: DN20
• Pattern: Angle
• Function: Integrated pre-setting for hydraulic balancing
• Application: Water-based central heating systems

How to use

The valve should be installed by a qualified professional to ensure proper integration with the existing heating circuit. Once installed, the pre-setting function is adjusted using a specialized tool to match the calculated flow requirements of the specific radiator. After the initial balancing is complete, a compatible thermostatic sensor head can be attached to the valve body to enable automatic temperature control based on room conditions.

What to consider before purchase

• Verify that the DN20 connection size matches your existing pipework
• Ensure the angle pattern is appropriate for your radiator inlet orientation
• Confirm compatibility with your chosen thermostatic sensor head
• Check if your heating system requires hydraulic balancing for optimal efficiency

Usage recommendations

Regularly inspect the valve for signs of leakage or corrosion during seasonal maintenance. Ensure that the pre-setting is not altered by unauthorized personnel to maintain the efficiency of the overall heating system.
