The DQ Essential TRV Straight Radiator Valves are supplied as a pair, bringing together a thermostatic valve with a matching lockshield for accurate temperature control and improved efficiency. Crafted from durable brass and available in eight finishes, their polished profiles — often seen in gleaming chrome but also in other contemporary and classic tones — highlight both precision engineering and lasting durability. The TRV head features a smooth cylindrical form with clear adjustment markings, while the compact lockshield provides a streamlined counterpart, creating a cohesive design pairing. Designed for straight pipework connections, they’re the right choice when pipes come directly from the floor into the radiator, and they use the standard ½″ BSP (15mm) fitting for compatibility with all DQ radiators and other UK models. Blending industrial functionality with everyday utility, these valves also come with a 2-year manufacturer’s guarantee.
