Válvula termostática para radiador DANFOSS RA-FN angular 3/8 polegada DN10 013G0001

The DANFOSS RA-FN Angle 3/8" DN10 thermostatic radiator valve is designed for angular installation on radiator supply lines to provide automatic room temperature control. It works by modulating water flow in response to a compatible thermostat head, enabling stable ambient temperature and reliable shut-off when the thermostat calls for isolation. The valve body and internal components are built to suit residential and light commercial heating systems that require compact angle fittings and dependable operation.

Advantages

This angled thermostatic valve offers precise flow modulation for improved temperature regulation, reducing overshoot and maintaining set-point stability. Its compact DN10 size and 3/8" connection enable installation in tight spaces and compatibility with common radiator fittings. The valve provides a reliable shut-off function when used with an appropriate thermostat head, helping isolate radiators for maintenance without draining the system. The design emphasizes durability and consistent hydraulic performance across typical household heating pressures.

Suitable for

• Residential radiators with angular supply connections
• Light commercial heating systems requiring room-level regulation
• Renovations where space for straight valves is limited
• Installations needing a reliable shut-off at the radiator

Key specifications

• Connection type: angle (90°) radiator valve
• Threaded connection size: 3/8"
• Nominal diameter: DN10
• Operation: thermostatic flow modulation with external thermostat head
• Mounting: angled supply line installation
• Typical application: hot-water central heating radiators

How to use

Install the valve in the radiator supply line with the correct orientation for an angled connection, ensuring thread sealing and firm mechanical connection. Mount a compatible thermostatic head onto the valve spindle according to the head manufacturer's instructions. After installation, bleed the radiator and check for leaks. Adjust the thermostat head to the desired room temperature; the valve will automatically modulate flow to maintain the set point and will close when the thermostat demands isolation.

Recommendations

Use compatible DANFOSS or equivalent thermostatic heads rated for this valve to ensure correct control behaviour. Verify system water quality and pressure are within common heating system ranges, and perform regular checks for leakage and proper operation. During commissioning, balance the system as needed to achieve even room temperature distribution.
