With wipe clean surfaces and modern design the TRV4 Chrome is an ideal radiator valve for bathroom with heated towel rails, with an elegant chrome finish. Select from compression connections 15mm, 10mm or 8mm, or push-fit connection to plastic and copper pipe.
How does a Drayton TRV4 work?
Each and every Drayton TRV4 features unique non-stick plastic internals as standard to prevent sticking, and ensure that when the colder weather hits, TRVs will always open. The plastic internals also mean that calcium is unable to build-up.
Should steam radiator valves always be open?
A one-pipe steam radiator valve should be fully open or fully closed, never in between. Steam vents allow air to escape from the radiator but shut automatically when the radiator is full of steam.
How do you know if a radiator valve is open or closed?
Check the radiator control valve: If a radiator is not getting hot: (steam or hot water) first see if the valve that controls it has been turned off. Try turning the valve counter-clockwise to see if it will open.
What temperature is 3 on a TRV?

How long do thermostatic radiator valves last?
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.
Should steam come out of radiator valve?
Unless you want to shut off the radiator completely, you must leave the valve all the way open at all times in a one-pipe steam heating system.
Can you close the valve on a steam radiator?
Radiator valves, even though they have a handle, are not meant to be closed or half-open. Closing or opening the valve partially, will not control the heat coming from your radiator. Steam radiator valves must remain fully open at all times.
What are the 2 valves on a radiator?
Radiators typically have two valves located on the pipes that allow hot water to enter them. The main one, which more people are familiar with (often called a ‘control valve’), is used for turning on and off your radiator in normal use. The second is your lockshield valve.
What position should radiator valves be in?
Many modern homes will have TRVs – Thermostatic Radiator Valves – attached to most of the radiators on the opposite side from the lockshield valves. A TRV should always be fitted to the inlet on the radiator and the LSV to the outlet.
What number should my TRV be?
A fully functional TRV will detect the temperature of the room and automatically adjust the amount of hot water in the radiator accordingly. During the winter, you should really set your TRV to 2 or 3 and leave it.
What number should radiator valves be set at?
Radiator valves have numbers or symbols to represent how much heat the radiator is putting out. Normally, these numbers range from 1 – 6. Turning the valve to 3 should give you a room temperature around 20°C. Each number above or below then represents a single degree.
Can I change a radiator valve without draining the system?
However, if you are only updating one radiator you can change the radiator valve without fully draining the system and there are actually benefits of doing so. For example, the water in your central heating system is filled with heating additives and inhibitor which protect the system.
How do I free a stuck TRV valve?

Do thermostatic valves fail?
Sometimes, a failing TMV makes the water too cold. Or, water may not run at the right temperature consistently. It may fluctuate between being hot and cold. In some cases, a faulty TMV can also affect your cold tap.

Why is my radiator releasing steam?
If a steam radiator makes gurgling noises, either from the air vent or from the radiator itself, it’s usually a sign that condensed water is being trapped in the radiator rather than draining back down to the boiler. This can be the result of problems with the radiator itself, the control valve, or the air vent.
Why is my radiator steaming but not overheating?
The most common answer to, “Why is my car smoking but not overheating?” is that there’s a type of fluid that’s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it’s burning off that fluid from the engine.
Why does my steam radiator spit out water?
An air vent that’s spitting or leaking water may be partially obstructed with mineral deposits or other debris. For either of these issues, try a good cleaning with vinegar. If that doesn’t solve the problem, replace the valve or vent.
How do you regulate the heat on a steam radiator?
However, there is one way to adjust the heat on a steam radiator: installing a thermostatic radiator valve. This adjusts room temperature by using air to reduce or increase the amount of steam that warms your radiator. Radiators come in two types: one-pipe and two-pipe. They have different types of boiler systems.
Should both valves on radiator be open?
You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.
Should radiator lockshield be fully open?
Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).
Why are there 2 valves on a radiator?
Each radiator will have two valves. One will control the amount of hot water that enters the radiator and the other will balance the system by controlling how much heat comes out of your radiator.
