The Drayton RT212 15mm thermostatic radiator valve pack provides precise, low-cost thermal regulation for individual rooms within wet central heating systems. Featuring a high-quality liquid-filled sensor, the TRV delivers rapid and accurate response times to ambient temperature fluctuations to optimise energy efficiency. The 15mm angled reverse-flow body allows for highly flexible installation in any flow direction, preventing water hammer issues commonly associated with directional valves. Engineered with a maximum operating pressure of 10 bar, this robust brass and chrome assembly ensures secure and reliable long-term performance.

Designed for straightforward integration, the pack includes a matching lockshield valve to facilitate accurate hydraulic balancing across the radiator network. The thermostatic head incorporates an integrated 8 degrees Celsius frost protection setting alongside a precise range-limiting feature to prevent unauthorized over-adjustment. The double gland seal provides an extra layer of operational security against leaks. Finished in a professional chrome plating, the valves offer a durable and aesthetically unobtrusive solution compatible with a wide range of plastic and copper pipework via optional adaptors.

Q: What type of sensing mechanism does the thermostatic head use?
A: The head contains a responsive liquid-filled sensor to accurately detect and react to room temperature changes.

Q: Can the valve be installed on either side of the radiator?
A: The reverse-flow angled body allows the valve to be mounted on either the flow or return pipework.

Q: Does the TRV include a frost protection setting?
A: It features a built-in 8 degrees Celsius frost protection threshold to safeguard the system in freezing conditions.

Q: What is the maximum system pressure this valve can withstand?
A: The robust construction is rated to handle a maximum operating pressure of 10 bar.
