A Vaillant bypass valve assembly for installation in ecoTEC VU (condensing), ecoTEC VUI (condensing), ecoTEC VUW (condensing), ecoFIT VU (condensing), Guernsey/Jersey only (condensing), ecoFIT VUW (condensing) and Home (condensing) appliances. The bypass valve, or flow regulator, controls the direction and flow rate of fluid in heating and plumbing systems. These valves can act as checking valves, helping to prevent the drift of fluids into the wrong areas of a system. We carry over 300 of the most in demand parts in-branch and stock over 25,000 spare parts available for next-day timed delivery.
