Are Danfoss TRVs bidirectional?

Danfoss’s ‘flow selectable’ bi-directional TRV can be installed horizontally or vertically, in flow or return. If any noise occurs after fitting it can be stopped by simply ‘revolving’ the patented flow direction selector on the valve head from the factory-set position to the alternative setting.

How does a Danfoss radiator valve work?

A thermostatic radiator valve consists of two main components: the valve itself and a thermostat. The distance between the valve seat and the valve cone determine how much water is flowing through the valve and to the radiator. The valve cone is operated by the thermostat, which senses change in the room temperature.

Do thermostatic radiator valves wear out?

You should replace your thermostatic radiator valves (TRVs), or at least upgrade the TRV heads, if they are 10 or more years old. TRVs can decline in terms of performance and accuracy over time. To learn more about what TRVs are and why they may be beneficial, check out our guide to Thermostatic Radiator Valves.

What is an RA valve?

The RA-C valve can be used for heating or cooling, so the choice of thermostatic or electronic operators or controls will determine if the valve will open or close on a rise or fall in room temperature. RA-C is a normally open valve, with four possible pre-settings, ensuring the correct water flow to each circuit.

Is a radiator valve the same as a lockshield?

They work in a similar way to taps, allowing water in and out of the radiator. One valve controls the hot water flow into the radiator, and the lockshield valve controls the heat coming from the radiator.

What is a Danfoss valve?

Danfoss Dynamic Valve™ is an innovative radiator valve with a 2-in-1 valve design. It combines a thermostatic radiator valve and a differential pressure controller for accurate temperature control and automatic hydronic balancing in a single product.

What can go wrong with a thermostatic radiator valve?

The most common and regularly occurring problem with a thermostatic radiator valve is that the valve – or the head of the valve – begins to stick or catch. This will leave them open or closed and can happen when the setting on the valve has not been adjusted for some time – such as at the end of a long hot summer.
