Description
The TRV4PACKSTAN Straight Anthracite TRV Pack is a straightforward domestic radiator valve set intended for standard 15mm central‑heating pipework. It combines a liquid‑filled thermostatic head with a straight valve body plus a matching lockshield and the small fittings you need to fit or replace a radiator connection: two 1/2″ BSP tails, two 15mm olives and decorator caps. The finish is a hard‑wearing anthracite powder coat on brass hardware, designed to match contemporary radiators and towel rails where a darker trim is preferred over chrome.

How it controls temperature and what that means day‑to‑day
The thermostatic head contains a liquid sensor that reacts to room air temperature. Turning the head moves a pointer across a 0–5 scale that corresponds to approximately 7°C up to 28°C, with an integrated frost position below 7°C. The liquid sensor and the listed hysteresis of 0.2K mean the valve will make small, frequent adjustments to hold the set temperature rather than oscillating wildly—useful in rooms where you want a steady ambient temperature without continually heating the whole house.
Installation, orientation and compatibility
The valve body is reversible so it may be fitted on either flow or return and the head can be mounted horizontally or vertically to suit pipework routing. It’s supplied with standard 1/2″ BSP radiator tails and 15mm olives, so it’s intended for the common UK radiator and towel‑rail connections. The pack also includes decorator caps to seal the valves when a radiator is removed for decorating or maintenance. The manufacturer’s datasheet advises that installation work should be carried out by a professional and gives simple fitting steps for attaching the head to the body.
Finish, materials and durability
The functional parts are brass with an anthracite powder‑coated finish on the visible components. That finish is chosen for a contemporary aesthetic and for scratch resistance compared with painted alternatives, while the brass construction gives the usual corrosion resistance expected from central‑heating valves. The datasheet specifies a maximum working pressure of 10 bar and a maximum flow temperature of 110°C, so the pack is suitable for domestic systems and higher‑temperature applications within those limits.
Practical points for buyers and installers
This pack is a practical, low‑risk upgrade when you need a matching TRV and lockshield in an anthracite finish: it includes the small fittings installers expect, so you don’t need to hunt for olives and tails. The reversible body and horizontal/vertical head mounting make it flexible for a variety of radiator positions. If your radiator or pipework uses non‑standard thread sizes, older imperial fittings or bespoke proprietary connections, check compatibility before purchase — the product is designed for 15mm pipe and 1/2″ BSP radiator threads.
In short, the TRV4PACKSTAN suits homeowners and installers who want a contemporary anthracite finish in a compact, ready‑to‑fit pack that meets EN215 and BS7556 standards. It’s not a smart‑home device — it’s a conventional thermostatic radiator valve pack built for reliable manual control and tidy appearance.
