The RLV-D range of domestic lockshield valves are identical in finish and dimensions to the RA-FS valve bodies used with the RAS-D2 and RAS-C2 radiator thermostat combi packs. All of the fittings, including the tailpieces, are fully interchangeable for total ease of installation. Available in angled pattern 15mm and 8/10mm sizes with conventional compression fittings and in a version incorporating a 10mm push-fit elbow, the valves are ideal for new build, repairs and system upgrades. Adjustment of the lockshield valve is by means of a 6mm Allen key. The setting cover is nickel-plated brass, which is screwed onto the valve body.
