Product Information
Full details
This Danfoss RAS-C2 straight thermostatic radiator valve (TRV) and lockshield set is designed for homeowners and plumbers seeking reliable and precise radiator temperature control. Its key benefit is preventing water hammer and offering tool-free installation for ease of use. A potential caveat is that while it offers frost protection, it doesn't provide active heating control beyond ambient temperature regulation. This set features a bi-directional valve body with an integrated liquid sensor and a matching lockshield valve, enabling efficient and adaptable radiator performance.

Extended Product Information
FAQs
What temperature range does the RAS-C2 sensor cover?
The integrated liquid sensor provides precise temperature control within a range of 8–28°C.
Can I install this valve on either the hot or cold pipe?
Yes, the valve body is bi-directional and can be mounted on either the flow (hot) or return (cold) pipe.
How do I fix water hammer with this valve?
The valve features a patented flow selection device. By turning this device, you can reverse the water direction inside the valve without needing to drain the system, which can resolve water hammer issues.
Is this valve compatible with all heating systems?
This valve is designed for standard 15mm radiator pipework and is compatible with most conventional wet central heating systems.
Do I need special tools to install the sensor head?
No, the new style RAS-C2 sensor head is designed for tool-free fitting. It simply pushes onto the valve body until it clicks.
What does the lockshield valve do?
The lockshield valve is used to balance the heating system. It is typically set during installation and rarely needs adjustment afterward, but it allows for isolation of the radiator.
Does this valve have frost protection?
Yes, the valve includes a frost protection setting to help prevent the radiator from freezing in cold ambient conditions.
Troubleshooting
Radiator not heating up at all
Check that the valve is not set to the lowest setting or frost protection. Ensure the lockshield valve is fully open. Verify the central heating system is operational.
Radiator is constantly fully hot, even on low settings
The valve head may not be properly engaged with the valve body, or the valve pin might be stuck. Ensure the head is clicked on correctly. If the pin is stuck, try gently tapping it or using a pliers to carefully pull it up. If the issue persists, the valve body may need replacement.
Water hammer noise from the radiator
If the noise occurs, the patented flow selection device within the valve can be turned to reverse water direction inside the valve without draining the system. Refer to the product manual for specific instructions on how to access and adjust this feature.
Valve head is difficult to turn
Ensure there are no obstructions. If the valve has been set to a low setting for a long period, the pin might be slightly stiff. Try turning it to the maximum setting and then back down. If it remains stiff, a gentle application of penetrating oil to the pin might help, but avoid excessive use.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Ensure the heating system is turned off and the radiator has cooled.
- Isolate the radiator using the lockshield valve and any existing radiator valve.
- Unscrew the old radiator valve head and body (if applicable).
- Screw the new Danfoss RA-FS valve body onto the radiator tail. Tighten by hand, then an additional quarter turn with an adjustable spanner if needed, ensuring it is secure.
- Attach the RAS-C2 sensor head to the valve body by pushing it firmly until it clicks into place. No tools are required for this step.
- Open the lockshield valve slowly and bleed the radiator if necessary.
- Turn the heating system back on.
Compatibility:
- This valve is designed for standard 15mm radiator pipework. It is compatible with most conventional wet central heating systems.
- The valve body is designed for installation on either the flow or return pipe, offering versatility.
Care:
- The sensor head can be wiped clean with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Periodically check that the valve operates smoothly and that the temperature setting adjusts the radiator output.
- Ensure the frost protection setting is appropriate for your climate if you intend to use it.
