The Drayton TRV4 White 15mm Angled TRV & Lockshield Valve Pack (MPN 07 07 260) is a complete radiator valve pack in the TRV4 White finish, pairing a 15mm angled thermostatic valve with a matching white lockshield — everything needed for both ends of a radiator connection in one box.
The TRV4 White carries the same TELL Class I energy efficiency rating as the TRV4 Classic, making it one of the most energy-efficient TRVs available, and is Keymark approved to EN215. It's a self-operating valve that regulates the flow of hot water to the radiator to control room temperature, with the lockshield fitted at the opposite end to balance the system or isolate the radiator.

Max Static Pressure
ℹ Good to Know: This pack includes both the TRV4 sensing head and 15mm angle valve, and a matching white 15mm angle lockshield — no separate lockshield purchase is required.
Class I Energy Efficiency
The TRV4 White has been awarded the highest “A” / Class I rating for energy efficiency by the European valve manufacturers' association (TELL EU), the same rating as the TRV4 Classic.
Keymark Approved to EN215
Rigorously tested and Keymark approved to the EN215 European Standard, demonstrating the highest standards of quality, reliability, energy saving and safety.
Contemporary White Finish
A clean, contemporary white finish suits modern white radiators and bathroom installations where a discreet, unobtrusive valve is preferred.
Reverse Flow Body
The 15mm angled body supports installation on the flow or return, with the sensing head fitted vertically or horizontally.
Double Gland Seal
A double gland seal protects against water leakage, with a top seal allowing head removal for servicing without draining down the system.
Balance From the TRV
Pre-setting internals let installers balance the radiator's flow rate directly from the TRV, simplifying system commissioning.
