Drayton TRV4 Classic 15mm White Chrome Angled TRV Integral Head 07 05 150

Drayton TRV4 Classic 15mm White Chrome Angled TRV Integral Head 07 05 150

The Drayton TRV4 Classic 15mm Angled TRV with Integral Head (MPN 07 05 150) is the most widely specified thermostatic radiator valve in the UK — a complete angled TRV4 unit comprising the 15mm compression valve body and the liquid-filled classic sensing head. Rated TELL Class I for energy efficiency and approved to BS EN 215, it suits virtually all domestic and light commercial wet heating systems. The reverse-flow body allows installation on flow or return; the pre-setting insert enables system balancing from the TRV without a separate tool.

Temp. Range
System Flushing Required
After installation, flush the heating system in accordance with BS7593. Do not add mineral-oil-based products to the system after flushing — these will damage valve internals.
Differential Pressure
Differential pressure across TRVs should not exceed 0.2 bar to prevent flow noise. Fit a Drayton DTB automatic by-pass valve where multiple TRVs may close simultaneously (see datasheet D30).
This SKU Is the TRV Only
MPN 07 05 150 is the angled TRV body with integral head, without a lockshield. For a complete valve pair (TRV + lockshield), choose MPN 07 05 180.
Key Features
🔁
Reverse Flow Body
The 15mm angled body accepts flow in either direction and the head can be oriented vertically or horizontally — no special body variants needed for different pipe configurations.
⚖
Pre-Set Balancing
The flow-rate adjustment insert allows system balancing directly at the TRV body using a Drayton balancing key — reducing reliance on separate lockshield adjustment.
💧
Double Gland Seal
Two gland seals prevent leakage. The top seal allows head removal without draining down — a significant practical advantage on occupied installations.
🏆
TELL Class I Rated
TELL Class I rates how quickly the valve responds, how well it holds setpoint, and its stability under pressure and temperature variation — Drayton TRV4 Classic achieves the highest possible rating.

Frequently Asked Questions
Can this valve be fitted on the return pipe instead of the flow?
Yes. The TRV4 15mm angled body features reverse flow as standard, so it can be installed on either the flow or the return pipe without any modification. Head orientation (vertical or horizontal) is also freely selectable.
Is a lockshield valve included?
No. MPN 07 05 150 is the TRV valve body and head only. A lockshield should be fitted at the opposite end of the radiator. For a complete TRV and lockshield pack, choose MPN 07 05 180.
How do I balance the system using the TRV?
The pre-setting facility on the TRV4 body allows you to restrict flow through an individual radiator using a Drayton balancing key. Set the Kv value appropriate to the calculated flow requirement before commissioning. See Drayton datasheet D10-18 for Kv values.
What lockshield matches this TRV?
The TRV4 Classic range uses chrome-finish lockshields. The matching 15mm angled chrome lockshield with chrome cap is MPN 07 05 917. Alternatively, order the complete pack MPN 07 05 180 which includes both the TRV and lockshield.
Will the TRV4 head from an older radiator fit this body?
Yes — TRV4 sensing heads are interchangeable across TRV4 bodies (Classic, Chrome, White, and Anthracite). However, TRV3 heads are not compatible with TRV4 bodies.
