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.
What is the lockshield on a radiator?
The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don't accidentally change the setting once you've adjusted it.
Do I need 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.
Which radiator valve is the lockshield?
Lockshield valves explained The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don't accidentally change the setting once you've adjusted it.
Do all radiators have a lockshield valve?
Unless your radiators have TRVs fitted, they will usually have a wheelhead and a lockshield valve, one on each end.
Should lockshield valve be open or closed?
One question that comes up a lot is “Should lockshield valves be fully open?” Well, it is not quite as simple as that! The lockshield valve should be set to a degree that will allow the radiator or radiators to maintain their desired temperature.
Does the lockshield valve go on the flow or return?
A lockshield valve (LSV) is 1 of 2 radiator valves that control the flow of hot water through each radiator. It's typically placed on the return pipe, and derives its name from the plastic cap that protects the valve from being accidentally turned.
Does the TRV need to be on the flow or return?
Most modern thermostatic radiator valves are bi-directional so can be fitted on either the flow or return pipe of your radiator. However, it's always best practice to fit the TRV on the flow pipe that enters your radiator.
What position should a lockshield valve be in?
It's typically placed on the return pipe, and derives its name from the plastic cap that protects the valve from being accidentally turned. If your home is equipped with Thermostatic Radiator Valves (TRVs), the latter automatically regulate the flow (supply) of hot water to the radiator.
Does it matter which side you fit a TRV?
The vast majority of new TRV's are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.Jan 1, 2012
How do I know which is the inlet and outlet on radiator?
Finding out where the valve inlets are located on your radiator is fairly straight forward and is defined by the type of radiator you have. For example, you tend to find the valve inlet on a towel rail radiator located underneath the bottom of the radiator.
