The Drayton TRV4 15mm Angled Valve Body (MPN 07 15 180) is the valve body only, supplied without a sensing head. It's intended for installers replacing a worn valve body while reusing an existing TRV4 sensing head, or for new installations where the head is being purchased and fitted separately.
The body carries the same internal performance as the rest of the TRV4 range, including non-stick valve internals, a double gland seal, and a pre-setting facility to balance the radiator's flow rate directly from the valve. As a 15mm angled body, it accepts any standard TRV4 sensing head via the M30 x 1.5mm fitting.

⚠ Important Safety Information: This product is the valve body only — no sensing head is included. A compatible TRV4 sensing head must be purchased separately for the valve to function as a thermostatic radiator valve.
Body-Only Replacement
Ideal for replacing a worn or damaged valve body while keeping an existing, working TRV4 sensing head, avoiding the cost of a full valve and head assembly.
Reverse Flow Capability
The 15mm angled body supports installation on the flow or return, with the head fitted vertically or horizontally once attached.
Non-Stick Internals
Valve internals are specially formulated to resist limescale build-up, helping the valve continue to open and close freely over years of service.
Double Gland Seal
A double gland seal protects against water leakage, with a top seal that allows the sensing head to be removed without draining down the system.
Pre-Setting Balancing
The two-pipe body includes a pre-setting facility, allowing installers to balance the radiator's flow rate directly from the valve during commissioning.
Standard M30 Head Fitting
Accepts any TRV4-compatible sensing head via the standard M30 x 1.5mm thread, in Classic, Chrome, White or Anthracite finish.

Does this include a sensing head?
No, MPN 07 15 180 is the valve body only. A compatible TRV4 sensing head must be fitted separately for it to work as a thermostatic radiator valve.
Which sensing heads are compatible with this body?
Any TRV4-compatible sensing head with the standard M30 x 1.5mm fitting, including Classic, Chrome, White and Anthracite finishes.
Can this body be used with a TRV3 head?
No — TRV4 sensing heads are not compatible with TRV3 bodies, and this is a TRV4 body. Use a genuine TRV4 head, or the dedicated TRV4-to-TRV3 conversion head where applicable.
Can this valve be installed on the flow or return?
Yes, the 15mm angled body has reverse flow capability and can be installed on either the flow or the return pipework.
Why would I buy just the valve body?
It's typically used when replacing a worn or damaged valve body while keeping an existing, working sensing head, or when the head is being sourced separately for a specific finish.
