How to adjust lockshield valve
The lockshield valve is an essential component of a heating system. It is responsible for balancing the flow of hot water through radiator pipes. Proper adjustment of the lockshield valve ensures that each radiator in your home is evenly heated, significantly improving the efficiency of your heating system and reducing energy consumption.
Adjusting the lockshield valve may seem complicated, but it is a relatively simple process that you can do yourself with a few basic tools. This article will guide you through the steps to adjust the lockshield valve correctly, allowing you to tailor the heat output of each radiator to your preference.
Step 1: Identify the Lockshield Valve
Start by locating the lockshield valve on each radiator in your home. The lockshield valve is typically found on the opposite side of the radiator from the thermostatic radiator valve. It is usually covered by a protective cap or shield. Remove the cap to access the valve. Step 2: Prepare the Tools Before adjusting the lockshield valve, gather the necessary tools. You will need an adjustable spanner and a radiator key. If you do not have these tools, they can be purchased at most hardware stores. Step 3: Balance the Flow
With the tools at hand, you are ready to adjust the lockshield valve. Begin by turning on the heating system and letting it run for a few minutes to warm up. Select one radiator that you want to adjust and close the thermostatic radiator valve fully by turning it to the highest temperature setting. Next, use the radiator key to turn the lockshield valve gently clockwise until it is closed, then count the number of turns until you cannot turn it anymore. Note down or remember this number; it will be referenced later. Step 4: Open the Lockshield Valve Now, open the lockshield valve one and a half turns anticlockwise from the closed position. This will start the initial flow of water to the radiator. The aim here is to have a balanced and even flow of hot water to all radiators in your home. Observe the radiator you adjusted and feel the temperature of the radiator horizontally from the valve. If the temperature drops significantly from the valve, the valve needs further adjustment. Slowly open the lockshield valve by one quarter of a turn until you achieve a consistent radiator temperature from the valve to the edge of the radiator. Repeat this process for each radiator in your home. Properly adjusting the lockshield valve is essential in improving the efficiency of your heating system. By balancing the heat output of each radiator, you can maintain a comfortable temperature in every room in your home while reducing your energy consumption. Follow these steps carefully to ensure the optimal performance of your heating system.
Why adjust lockshield valve
The lockshield valve is an important component of a heating system. It controls the flow of hot water or steam to a radiator, and adjusting it correctly can help to ensure efficient and balanced heating throughout your home.

Identify the lockshield valve
Before attempting to adjust the lockshield valve, it is important to first locate it. The lockshield valve is a crucial component of a heating system’s radiator. It is one of two valves, typically located on either side of the radiator. The other valve, the thermostatic radiator valve (TRV), is used to control the temperature of the radiator.
To identify the lockshield valve, look for a small round cap or cover on one side of the radiator. The lockshield valve is usually found on the opposite side of the TRV. The cap or cover can be a different color or have markings indicating its purpose.
If there are no visual indicators, you can identify the lockshield valve by touch. Gently feel along the radiator for a valve that feels firm and fixed in place. The lockshield valve will not have a turning mechanism like the TRV, but it may have a small nut or screw that can be adjusted.
Once you have identified the lockshield valve, you can proceed with adjusting it to ensure the proper balancing of your heating system. Understanding how to adjust the lockshield valve is essential for maintaining an efficient and comfortable indoor environment.
Use a lockshield valve key
To adjust a lockshield valve, you will need to use a lockshield valve key. This key is a specialized tool that allows you to access the lockshield valve and make adjustments to the flow of hot water through it.
Step 1: Locate the lockshield valve
The lockshield valve is typically found on the opposite side of the radiator compared to the thermostatic valve. It is usually covered by a plastic cap or a metal plate. Remove this cover to expose the valve.
Step 2: Insert the lockshield valve key
Insert the lockshield valve key into the valve spindle. The key should fit snugly into the spindle, allowing you to turn it easily.
Tip: It’s a good idea to use a cloth or glove to protect your hand from the hot radiator while you are making adjustments.
Step 3: Make adjustments
Use the lockshield valve key to turn the spindle in a clockwise or counterclockwise direction. Turning it counterclockwise will increase the flow of hot water to the radiator, while turning it clockwise will decrease the flow.
Note: It’s important to make small adjustments and test the radiator temperature regularly to achieve the desired level of heat.
Once you have made the necessary adjustments, replace the plastic cap or metal plate and check the radiator for any leaks.
Using a lockshield valve key is a simple and effective way to adjust the flow of hot water through your radiator and ensure that it is working efficiently. Remember to take your time and make small adjustments to achieve the desired results.
Left or Right?
When it comes to adjusting a lockshield valve, it’s important to know whether you should turn it left or right.
In general, lockshield valves have a clockwise and counterclockwise direction for opening and closing. However, the direction may vary depending on the manufacturer and model of the valve. It’s always best to consult the manufacturer’s instructions or documentation for specific guidance.
To determine the correct direction for adjusting the lockshield valve, it can be helpful to consider the principle of “open to the ox” – this means that you should turn the valve in the same direction as an ox’s horns curve. In most cases, this means turning the valve clockwise to close it and counterclockwise to open it.
By turning the lockshield valve in the correct direction, you can adjust the flow of water through the radiator and balance the system.
If you’re unsure about the direction to turn the lockshield valve or are experiencing any difficulties, it’s always a good idea to seek professional assistance or advice.
| Turning Direction | Result |
|---|---|
| Clockwise | Closing the valve, reducing flow |
| Counterclockwise | Opening the valve, increasing flow |
Start turning the valve
Once you have removed the lockshield cap, you can start turning the valve using a valve key or adjustable spanner. The valve should turn easily, but if it feels stiff, you may need to use a bit more force. Keep in mind that you want to make small adjustments, so turn the valve slowly.
To begin with, turn the valve clockwise (to the right) to close the valve. This will reduce the flow of water to the radiator, allowing you to control the heat output. It’s important to close the valve fully before opening it again, as this helps to prevent any airlocks from forming in the system.
Once the valve is closed, you can start opening it by turning it anti-clockwise (to the left). Begin by opening the valve slightly and then wait for a few minutes to see if the heat output changes. If you are not satisfied with the heat output, you can continue to open the valve a little bit more, testing the heat output after each adjustment.
Remember that it may take some time for the heat to reach the radiator, so be patient when making adjustments. Also, keep an eye on the pressure gauge on your boiler to make sure the pressure does not drop too low. If you have any concerns or are unsure about adjusting the lockshield valve, it’s always best to consult a professional plumber.
Monitor the temperature
When adjusting the lockshield valve, it is important to monitor the temperature of the room or area of the building where the valve is located. This will help ensure that the valve is properly adjusted and that the desired temperature is achieved.
One way to monitor the temperature is by using a thermometer. Place the thermometer in a central location within the room and take regular temperature readings. This will give you an indication of the temperature and help you determine if any adjustments to the lockshield valve are needed.
In addition to using a thermometer, you can also monitor the temperature by observing how the room feels. If the room feels too warm or too cold, this can indicate that the lockshield valve may need to be adjusted.
It is important to note that the lockshield valve should only be adjusted by a qualified professional or by following the manufacturer’s instructions. Adjusting the valve incorrectly can result in damage to the heating system or inefficient heating.
| Temperature Readings | Adjustments Needed |
|---|---|
| Too Cold | Open the lockshield valve slightly to allow more hot water flow. |
| Too Warm | Close the lockshield valve slightly to restrict hot water flow. |
By monitoring the temperature and making appropriate adjustments to the lockshield valve, you can ensure that the room or area is heated to the desired temperature and create a comfortable environment.
