The Plumbright Straight Thermostatic Radiator Valve (TRV) and Lockshield set is ideal for homeowners looking to modernize their central heating system while gaining individual room temperature control. It offers an efficient, energy-saving solution by allowing users to manage heat output per radiator, though professional plumbing installation is recommended to ensure a leak-free, secure fit for standard 15mm connections.

This set is designed for standard 15mm pipes with a 1/2 inch BSP inlet.
No, this is a purely mechanical thermostatic valve and requires no electrical power, batteries, or external wiring.
The valve features 6 levels of adjustment, allowing for temperature settings between 6 and 28 degrees Celsius.
No, this is a straight valve set. You should verify your radiator tail configuration before purchasing.
The frost protection setting keeps the valve at a minimum temperature to prevent water in the radiator from freezing, which helps protect your pipes from bursting during extremely cold weather.
Yes, the product is compliant with the BS EN 215 standard for thermostatic radiator valves.
The internal valve pin may be stuck due to lack of use. Remove the TRV head and gently tap or push the pin to ensure it moves freely.
Ensure the union nuts are tightened correctly and check that the olive is seated properly. If the leak persists, consult a professional plumber as the joint may need additional PTFE tape or a replacement olive.
This is often caused by high water pressure or flow speed. Adjusting the lockshield valve on the other side of the radiator to balance the system can often resolve the noise.
This unit is designed for standard 15mm radiator tails connecting to 1/2 inch BSP inlets. Installation should be performed by a qualified plumber to ensure system pressure is properly managed and connections are watertight. Once installed, care is minimal: periodically wipe the grey casing with a soft, dry cloth to prevent dust accumulation. Do not use abrasive chemicals on the finish. Before the heating season begins, rotate the dial through its full range to ensure the internal valve pin remains free and responsive.
