Bentley Traditional 15mm Antique Copper TRV & Lockshield Set

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. TRV + Lockshield Valve Type Reversible Orientation 15mm Inlet Size Antique Copper Finish 2-100°C Water Temp Range 1 Year Warranty Reversible TRV Valve Can be installed on either side of the radiator, giving greater flexibility for pipework routing and installation. Antique Copper Finish A rich, warm finish that complements traditional brass taps, period radiators and heritage interiors. Thermostatic Control Automatically adjusts water flow to maintain your chosen room temperature, improving comfort and reducing heating costs. Lockshield Valve Included Allows the system to be balanced properly, ensuring consistent heat output across multiple radiators. High-Grade Brass Construction A robust brass body and precision-engineered internals for reliable, long-term performance. Easy Manual Adjustment A clear wheel head or dial for quick changes to the desired room temperature. Valve Details Valve type Reversible thermostatic radiator valve (TRV) with lockshield Valve inlet 15mm compression Valve outlet 1/2" BSP male radiator tail (standard) Construction Finish Antique copper Material Brass Performance Working pressure Max. 10 bar Pressure differential Max. 1 bar (suitable as reverse flow when differential is 0.25 bar or below) Water temperature range Min. 2°C - max. 100°C Ambient temperature range Up to 50°C Compatibility System compatibility Standard sealed central heating systems with flow/return pipework, suitable where auto bypass is installed Installation note Designed for use as a reverse-flow TRV when system differential pressure across the valve does not exceed 0.25 bar; an auto bypass should be fitted with all Bentley valves Warranty Manufacturer warranty 1 year, subject to terms and conditions 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.
