Add instant period elegance and precise temperature control to your radiators with the Bentley Traditional 15mm Antique Copper TRV & Lockshield Valve Set. This high-grade twin pack combines a reversible thermostatic radiator valve (TRV) and matching lockshield valve in a rich antique copper finish, designed for traditional column radiators, cast iron radiators, and classic towel rails in both homes and period properties.
Solid brass construction and precision-engineered internals ensure long-term reliability, while the lockshield valve enables precise system balancing for even heat distribution across larger homes or commercial properties. The reversible TRV design offers greater flexibility for plumbers and installers on system layouts.

What does 'reversible' mean for this TRV?
A reversible TRV can be installed on either side of the radiator - so whichever side your pipework approaches from, the valve can be fitted without needing a separate left- or right-handed version.
Why is antique copper suited to period properties?
The rich, warm antique copper finish is designed to complement traditional brass fittings, cast iron and column radiators, and other heritage-style details commonly found in Victorian and Edwardian homes.
Do I need an auto bypass valve with this TRV?
Yes. As with all Bentley valves, an automatic bypass valve should be fitted where this TRV is used as a reverse-flow valve, to maintain stable differential pressure across the system.
Does this pack include both a TRV and a lockshield?
Yes. This is a complete TRV and lockshield twin set - one thermostatic valve for temperature control, and one lockshield valve for balancing the system.
