The Drayton TRV4 Anthracite 15mm Angled TRV & Chrome Lockshield Pack (MPN 07 05 210) delivers TRV4 performance in a contemporary anthracite finish, responding to the surge in popularity of flat-panel and column designer radiators in dark grey and anthracite tones. The pack pairs a 15mm angled TRV4 body with anthracite liquid-filled sensing head with a chrome lockshield. The valve body is identical in performance specification to the TRV4 Classic — featuring reverse flow, double gland seal, and pre-setting balancing — though the Anthracite variant does not carry the TELL Class I rating.

Frequently Asked Questions
Does the TRV4 Anthracite carry the same Class I energy rating as the Classic?
No. The TELL Class I rating applies to TRV4 Classic and TRV4 White only. The Anthracite variant shares the same valve internals and is approved to BS EN 215, but is not separately assessed under the TELL Class I scheme.
Can I get a fully anthracite pair — TRV and lockshield both in anthracite?
The 07 05 210 pack pairs an anthracite TRV head with a chrome lockshield. If a fully matched anthracite lockshield is required, check Drayton's accessories range for current availability of anthracite lockshield options.
Is there a straight-body version of this pack?
Yes — MPN 07 05 211 provides the same anthracite head and chrome lockshield combination in a straight 15mm body configuration, for radiators where the pipework runs directly inline.
What radiator types suit this finish?
The anthracite finish is designed for anthracite, graphite, grey, or dark matt designer radiators — including horizontal and vertical flat-panel radiators, column radiators in dark finishes, and bathroom heated towel rails in anthracite.
How does the pre-setting facility work?
The pre-setting insert inside the TRV body restricts the maximum Kv (flow) when set using a Drayton balancing key before commissioning. This allows rough hydraulic balancing to be carried out at the valve itself. See Drayton datasheet D10-18 for the Kv table.
