Thermostatic Radiator Valve Set DANFOSS RA-N angle with PANDA thermostat head 1/2" (013G5163)

The DANFOSS RA-N angled thermostatic radiator valve set with PANDA thermostat head is designed for automatic room temperature regulation on hot-water radiators. The set includes an angled RA-N valve body and a PANDA thermostat head that together provide proportional control of radiator flow to maintain a stable indoor temperature. Intended for residential and light commercial heating systems, the valve set supports energy-efficient operation by modulating hot-water flow according to the selected setpoint.

Advantages

The angled RA-N valve body offers a compact installation profile for radiators with limited space near walls or piping, while the PANDA thermostat head provides accurate proportional control and easy manual setpoint adjustment. The combination enables quieter operation and smoother temperature regulation compared with on/off devices. Materials and design ensure compatibility with standard radiator connections and reliable performance in typical hot-water heating circuits.

Suitable for

• Domestic hot-water radiator systems in apartments and houses
• Light commercial heating zones such as offices and small retail spaces
• Retrofit projects where an angled valve body simplifies installation
• Applications requiring proportional temperature control to improve energy efficiency

Key specifications

• Valve orientation: angled configuration suitable for side and bottom pipe entries
• Connection size: 1/2" compatible with standard radiator fittings
• Control type: thermostatic proportional control via mechanical thermostat head
• Actuator: manual adjustable PANDA thermostat head for setpoint selection
• Fluid compatibility: designed for closed hot-water heating systems

How to use

Install the angled RA-N valve body on the radiator inlet using the 1/2" connection, ensuring proper sealing and alignment with the pipework. Mount the PANDA thermostat head onto the valve spindle and set the desired room temperature using the head's scale. The thermostat head will modulate the valve opening according to room temperature changes, reducing or increasing flow to maintain the selected setpoint. Commission the valve by checking for leaks and verifying that the radiator temperature responds to setpoint adjustments.

Usage recommendations

Position the thermostat head away from direct drafts, heat sources, or sunlit windows to ensure accurate room temperature sensing. For best performance, bleed air from the radiator before commissioning and verify compatibility with the system’s fluid and pressure parameters. Regular visual inspection and occasional valve operation checks help maintain reliable control and prevent sticking.
