Description
Zoloto bronze Double Regulating Balancing Valve (Screwed) with Nozzle, available 15 mm to 50 mm. Balancing valves set the design flow through each branch of a distribution circuit. Without them, the branches nearest the pump take more than their share and the far ends of the system never reach temperature. The LTB-2 gunmetal body to IS 318 resists dezincification, which is why gunmetal remains the default for potable water rather than a cheaper brass. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. The table above gives the catalogue reference and price for each size in the range.
