2 Bypass valve flow curve Under normal operating conditions, the bypass valve is totally sealed and there is no leakage bypassing the element. When pressure drop across the filter exceeds the preset level, bypass flow commences and increases as pressure drop increases. Thus full flow is ensured and the proportion of filtered flow is maintained at a maximum. The curve above is typical. Typical Flow/ressure Curves for 4-2 Filter (Double Length) BCK TO
