Thermostatic Radiator Valve DANFOSS RA-UN 15 angled, low kv (013G3003)

Angled thermostatic radiator valve DANFOSS RA-UN 15 with low kv value is designed for precise flow regulation in hot water heating systems. The compact angled body provides a right-angle connection to radiators and piping, while the low kv characteristic enables fine control of flow rate for stable room temperature and improved energy efficiency. The valve is compatible with DANFOSS actuators and standard thermostatic heads, making it suitable for installations where accurate hydraulic balancing and space-saving geometry are required.

Advantages

The RA-UN 15 angled valve features a low kv value that allows sensitive adjustment of flow through the radiator, which helps maintain consistent indoor temperatures and reduces overshooting. Its angled design simplifies connection in tight spaces and near-wall installations. Constructed for corrosion resistance and reliable operation, the valve integrates with common thermostatic actuators to permit automatic or manual control. The compact dimensions and precise control characteristics support efficient hydraulic balancing across multi-radiator systems.

Suitable for (tasks / use cases)

• Residential radiator installations with limited installation depth
• Commercial premises requiring precise room temperature control
• Renovation projects where compact angled connections are needed
• Systems requiring fine hydraulic balancing and low flow rates

Key specifications

• Type: Angled thermostatic radiator valve for radiator-to-pipe connection
• Flow characteristic: Low kv value for fine flow control
• Compatibility: Works with DANFOSS thermostatic actuators and standard valve heads
• Connection orientation: 90° angled body for compact installation
• Application: Hot water heating systems for residential and commercial radiators

How to use

Install the valve at the radiator inlet using appropriate fittings and follow the radiator manufacturer’s instructions for connection. Fit a compatible DANFOSS actuator or a standard thermostatic head to enable temperature control. For manual balancing, set the valve to the required flow position and verify room temperature response. For automatic control, connect the actuator according to its wiring and configuration guidelines and commission the system to ensure stable operation and correct hydraulic balance.

Usage recommendations

Use this angled low-kv valve where precise flow regulation is needed and where space constraints require a compact connection. During installation and commissioning, perform hydraulic balancing and test with the intended actuator or head to achieve optimal temperature stability and energy-efficient operation.
