ABBV1 auto-bypass valve

Description

Tower ABBV1 Automatic Bypass Valve
The Tower ABBV1 is designed for use in heating systems where a boiler bypass is necessary. It is particularly effective in systems equipped with thermostatic radiator valves (TRVs) and enables pump overrun functionality after zone valves close. By maintaining a consistent system pressure and ensuring constant flow, the ABBV1 enhances the efficiency and longevity of your heating system.

As TRVs gradually close when room temperatures rise, the ABBV1 compensates by adjusting to the required set point, allowing increased flow to maintain a pre-set system differential pressure. This helps to minimise noise caused by TRVs or zone valves closing, reduce wear on the pump impeller, and protect the boiler’s heat exchanger by ensuring a consistent minimum flow rate.

For installation, the ABBV1 should be placed in a loop between the flow and return after the pump, with the flow direction matching the arrow on the valve body. Set the desired pressure by rotating the adjustment head until the preferred setting number is visible, then lock it in place using the screw on the adjuster. Refer to boiler manufacturer recommendations and the specified pressure/flow rates for optimal performance.
