The Drayton TRV4 Classic 15mm Angled TRV & Lockshield Valve Pack (MPN 07 05 180) is the go-to complete valve pair for standard 15mm domestic radiator installations — supplying both a TELL Class I-rated TRV4 angled thermostatic radiator valve with integral head and a matching chrome angled lockshield valve in a single box.

Flush the system to BS7593 and treat with inhibitor before and after installation. Fit a by-pass valve where differential pressure across TRVs may exceed 0.2 bar.
What's In the Pack
One TRV4 Classic 15mm angled TRV body with integral white/chrome sensing head, plus one matching 15mm angled chrome lockshield valve — everything needed to connect both ends of a single radiator.
Key Features
📦
Complete Radiator Pack
One pack covers both radiator connections — TRV at the inlet, lockshield at the outlet. No separate sourcing of matching lockshields; both valves share the TRV4 Classic chrome finish.
⚖
Dual Balancing Options
The TRV body's flow-rate adjustment insert provides primary balancing; the lockshield provides fine trim. Use one or both approaches to suit your commissioning workflow.
🔁
Reverse Flow Angled Body
The 15mm body accepts flow or return installation and vertical or horizontal head orientation — adaptable to practically all standard domestic radiator positions.
💧
Double Gland Seal
The double seal prevents water loss and allows the sensing head to be removed without draining down — minimising disruption when carrying out head replacements or adjustments.

Frequently Asked Questions
What is included in the 07 05 180 pack?
The pack contains: (1) TRV4 Classic 15mm angled thermostatic radiator valve with integral white and chrome sensing head; (1) 15mm angled chrome lockshield valve. 15mm compression fittings are included with both valve bodies.
Is the lockshield an exact colour match to the TRV?
Yes. The lockshield supplied in this pack has the same chrome finish as the TRV4 Classic body, giving a consistent appearance at both ends of the radiator.
How does the lockshield help with balancing?
The lockshield restricts flow at the outlet end of the radiator, allowing fine-tuning of the flow rate to each radiator relative to others on the circuit. This ensures all radiators receive the correct flow, preventing some rooms overheating while others remain cold.
Is this pack suitable for all domestic heating systems?
Yes — the TRV4 is compatible with virtually all two-pipe wet central heating systems including condensing boiler systems, heat pump systems, and combination boiler installations. For UFH or single-pipe systems, different valve types are required.
Which pack should I choose — white/chrome (07 05 180), anthracite (07 05 210), or chrome (07 05 174)?
07 05 180 (Classic white/chrome) suits standard white panel radiators. 07 05 210 (Anthracite) suits dark or anthracite designer radiators. 07 05 174 (Full chrome) suits chrome-finish, bathroom, or period-style radiators.
