Altecnic Eres Automatic Angle Bypass Valve 28mm ER-28MMANGBI

This is a 28mm automatic angle bypass valve designed for use in domestic and commercial heating systems. It functions by regulating water flow and maintaining system balance, particularly where thermostatic radiator valves are installed.

The valve is installed in pipework to help maintain consistent flow rates and protect boiler performance. Plumbers and heating engineers typically fit this type of bypass valve to improve system efficiency and prevent noise or damage caused by excess pressure.
