The Pro Plus Straight TRV With Lockshield 15 is designed for DIY enthusiasts and homeowners looking to enhance their heating system's reliability and energy efficiency. Its key benefit is providing precise control over radiator heat output, leading to improved comfort and potential energy savings. A potential caveat for some users may be the need for basic plumbing knowledge for installation. This comprehensive valve set includes a thermostatic radiator valve (TRV) and a lockshield, offering complete control over water flow and ensuring balanced heat distribution. Featuring straight 15 mm connections and durable brass construction, it's built for easy integration with standard UK central heating systems.

A Thermostatic Radiator Valve (TRV) automatically regulates the water flow into a radiator to maintain a set room temperature, improving comfort and energy efficiency.
The lockshield valve is used to balance the heating system. It allows you to set a permanent flow rate for a specific radiator, ensuring other radiators receive the correct amount of hot water.
Yes, the Pro Plus Straight TRV With Lockshield 15 is designed for DIY installation. However, basic plumbing knowledge and tools are required, and care must be taken to avoid leaks and system damage.
This valve is designed for standard 15 mm pipework with straight connections.
The TRV head has a numbered dial (usually 1-5). Higher numbers correspond to higher temperature settings. You can adjust it to your desired comfort level.
No, this is a manual thermostatic radiator valve and does not have smart home connectivity or programming features.
The product is backed by statutory guarantee, providing assurance of its quality and performance.
Ensure the TRV head is not turned down to the frost setting (often marked with a star or snowflake) or '0'. Check that the lockshield valve is fully open. Verify that the central heating system is functioning correctly and hot water is reaching the radiator.
Turn the TRV head to a lower temperature setting. Ensure the TRV head is correctly fitted to the valve body. If the issue persists, the TRV may be faulty or incorrectly sized for the radiator.
Carefully remove the TRV head. Gently use pliers to pull the valve pin outwards. If it moves freely after this, refit the head. If the pin is stuck, more force may be needed, or the valve may require replacement.
Turn off the water supply to the radiator. Gently tighten the compression fittings at the radiator and pipework. If leaks persist, you may need to dismantle the connection, check the integrity of the fitting and pipe, and re-seal if necessary.
The lockshield valve on each radiator needs adjustment to balance the system. Close all lockshields, then open them partially (e.g., 1-2 turns). Adjust the lockshields on radiators that heat up too quickly to restrict flow, and on those that heat up slowly to increase flow, until an even heat distribution is achieved.
Setup:
Compatibility:
This valve is designed for standard UK central heating systems using 15 mm pipework. It is compatible with most radiators that have standard valve connections. Ensure your pipework enters the radiator horizontally for the straight TRV to fit correctly.
Care:
Periodically (e.g., annually), test the TRV head by turning it to the highest setting to ensure it moves freely and does not stick. To do this, remove the TRV head and gently push and pull the pin visible on the valve body. Clean the exterior of the valve and TRV head with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
