What is the difference between a straight and angled radiator valve?
Straight radiator valves don’t incorporate any curves or bends, instead connecting to a bathroom radiator or standard designer radiator up from the floor. Angled valves are usually used to provide a clean finish, concealing pipework and plumbing more effectively than their straight counterparts.
How do I know if I need straight or angled radiator valves?
Side connections with pipes coming up from the floor = you need “angled” valves. Underside connections with pipes coming up from the floor = you need “straight” valves. Side connections with pipes coming out of the wall = you may choose between “angled” or “corner” valves.
Should radiator lockshield be fully open?
if so the lockshields are meant to be fully open and at least one rad must have non-TRV valves fittedm also with valves fullt open. as htg says, on a new system no problem, unless you want to be fussy about the 12 degree temp difference across the flow & return.2008-11-30
What does a lockshield valve do?
The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room.2021-07-26
How far should I open a lockshield valve?
You should open the Lockshield valve on the first radiator by one-quarter of a turn. Now open the Lockshield valve on the last radiator on your list. Each radiator in between should have its Lockshield valve opened slightly more than the previous radiator.
What happens if all lockshield valves are fully open?
On a new system all lockshields valves fully open – probably no problem, but as the system parts get older (pump etc) you may find some rads will get hotter than others – then balancing will be necessary.2008-11-30
What are corner valves for?
Corner radiator valves are ideal for connecting your radiator to the central heating pipework at a 90 degree angle without the valve head protruding into the room.
Are radiator valves different?
There are a few different types of radiator valve and they all do the same job. The name just describes the shape of the valve and how it connects the radiator to the pipework. For example, angled radiator valves connect the pipework to the radiator at a 90-degree angle.2019-10-11
What is an angled valve?
Angled radiator valves are used to connect the hot water pipes on a central heating system to a radiator. The points of connection are at a 90 degree angle which are useful when when the pipework comes out of the wall or from below the floorboards.
How do you set a lockshield valve?
Once the system has cooled down, you will have to open the lockshield valve. To do this, simply turn in an anti-clockwise direction (to the left). You can do so by hand; but if your valves are a bit stiff, use your lockshield valve key, a spanner, or the wheelhead valve cap instead.2022-03-22
What are the 2 valves on a radiator for?
One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
Do all valves fit all radiators?
You’ll probably need a set of 15mm valves for your radiator, but if you’re unsure then measure the diameter of your copper pipes to double check. The connection between your valve and the radiator is standard across all moderns radiators and valves.2021-01-26
How do I know which radiator valves I need?
Find The Radiator Inlets The inlets are where your valves will connect the radiator to the pipework. Therefore, it’s important to look at where and how they will connect as this will determine which shape valve you need. Most radiators have valve inlets at the bottom of the radiator on each side.2019-10-11
Do I need a lockshield valve?
A lockshield valve helps to balance out that radiator and ensure the whole system is in sync, with all radiators heating at the same rate. It is therefore every bit as important a valve as without the system being balanced, there is often little point adjusting an individual temperature valve.
How do you know if a lockshield valve is open?
How to Tell if the Radiator Valve Is Open or Closed? This is a common question, but the answer is dead simple. Turn it all the way to the left, and if it won’t go anymore, it’s closed. Otherwise, it’s some degree of open.2022-03-22
What is the difference between angled and corner valves?
Angled and corner valves are essentially the same shape so they can be used interchangeably. The choice is more form than function as it depends which direction you want the valve head to face.2019-10-11
Are there different types of radiator valves?
This is pretty simple there are two main types of radiator valve, these are manual and thermostatic and, for safety, there is also a lockshield valve.2019-03-16
Are radiator valves universal?
With a large variety of radiators currently available on the market in varying shapes, styles and sizes, not every valve is universally suitable to all radiators.
Should both valves on a radiator be fully 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.2014-04-17
How many turns on a lockshield valve?
Most LS valves are only effective over the first 1½ turns, the remaining 2 or more turns have no effect. This is why fine adjustments need to be made, e.g 1/12th turn, not ¼ or ½ turn. You may still need resistance on the last rad if the temperature drop is too small.2017-12-15
What are angled radiator valves used for?
Angled radiator valves are true to their name as they connect the radiator with the central heating pipework at an angle, generally 90 degrees. They are used when the pipework comes out of the wall or from below the floorboards and will therefore need an angle to be able to fit into the radiators inlet connection.2013-05-01
What position should a lockshield valve be in?
A lockshield valve (LSV) is 1 of 2 radiator valves that control the hot water flow through each radiator. It’s typically placed on the return pipe, and derives its name from the plastic cap that protects the radiator valve from being accidentally turned.2022-03-22
