Altecnic GLW Ecopas Differential BY-PASS Valve 22mm Compression 519002

This differential by-pass valve features 22mm compression fittings for straightforward installation within domestic or commercial central heating systems. It is designed to regulate system pressure by diverting flow when required, helping to protect pumps and maintain consistent performance throughout the heating circuit.

Typically used by installers during new boiler upgrades or when balancing heating systems, this valve automatically adjusts to variations in water flow. It is suited to pipework where by-pass control is needed between flow and return circuits, supporting system efficiency and reducing undue strain on components.
