What should the Lockshield valve be set to on a radiator?
The lockshield valve should be set to a degree that will allow the radiator or radiators to maintain their desired temperature. This can vary from one building to another, and there are many factors that go into determining this setting.
Do radiator valves need to be on the flow or return?
Its a process known as convection and the heat will still pass through from the flow and return pipes on the circuit. most modern TRVs have no orientation, you can fit them on the flow or return and they will work. Furthermore, does side of radiator valve matter?
Can You Bleed radiators with lockshields?
Yes indeed just forget the flow direction and use the lockshield to restrict flow as necessary. The only point to remember is if radiators with lockshields in the flow require bleeding, the heating may need to be turned off first.
What is a Lockshield valve?
Located near the top, between the home’s pipes and radiators or baseboard heaters, lockshield valves are usually covered with a plastic cap and are used to balance the heating system.
Which side of the radiator should the lockshield be?
Systems are normally balanced by adjusting the lockshield valves usually fitted on the return side of each radiator.
What position should a lockshield valve be?
The lockshield valve should be set to a degree that will allow the radiator or radiators to maintain their desired temperature.
Should radiator valve be on flow or return?
Should TRVs be installed on the flow or the return pipe when fitting a radiator? 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.
Does it matter which side the valve go on a radiator?
Unlike old TRV's and lockshield valves most modern valves will now work in either direction, and it is no longer standard to fit as you mention. Generally most installers fit the TRV on whichever end is open to the room.
How do you fit a lockshield valve?

And what the dark does that just holds the valve onto the red.
Which way do radiators flow?
leftThe flow of a radiator is typically on the left as you look at it stood up or attached to the wall.
What happens if flow and return are reversed?
If the pipes are reversed, the sensor will record the lower temperature and could compensate to make up the difference. This can result in unwanted noise, or overheating and inefficiency.
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).
Which side of radiator controls heat?
left sideThermostatic valves Step 1: You'll usually find the valve on a TRV radiator on the left side. The valve you're looking for will have a numbered dial on it, to adjust the heat the radiator gives off, and is usually found on the bottom of the radiator.
Can you heat a lock if you don't have a TRV?
If you don't have TRV's it really shouldn' t make much difference what side is the lockshield as long as the system is balanced properly (not to the extent that you can't get any heat at all anyway)...
Can you use a TRV as a L/S?
As stated already there is little or no difference to a wheelhead valve to a L/S. In fact you could even use a TRV as a L/S if you have the correct cap.
What is a lockshield valve?
A lockshield or a lockshield valve is a type of radiator valve. It connects a radiator to the return pipe to the boiler. It is one of two valves normally found on radiators, the other being the TRV (thermostatic radiator valve). A lockshield can easily be identified by its small white plastic cap. However, unlike a manual radiator valve (which also ...
What is the purpose of a lockshield?
The purpose of a lockshield is to regulate the flow of water through a radiator. Water pumped through the central heating circuit by the boiler will take the path of least resistance when it returns to the the boiler via the return pipe.
What is balancing radiators?
This ensures that the radiators heat up at the same rate and that the temperature in each room is equal. This is known as balancing the radiators. Generally speaking, the further away a radiator is from the boiler, the more open the lockshield valve needs to be, and vice versa.
Can a lockshield be adjusted without tools?
A lockshield can easily be identified by its small white plastic cap. However, unlike a manual radiator valve (which also has a small white plastic cap), it cannot be adjusted without tools.
Can you adjust a radiator spindle with a pliers?
The plastic cap should be replaced to prevent the valve from being adjusted again. Even if the cap is removed, however, the spindle can only be adjusted with a pair of pliers or an adjustable spanner.
