Compact double shut-off valve

A filter assembly comprising:

• a manifold module having a portion of a supply line, a portion of a discharge line, and a valve passage fluidly connecting the portion of the supply line to the portion of the discharge line;
• and
• a valve member extending along a longitudinal axis and having an unfiltered inlet fluidly connected to the portion of the supply line and an unfiltered outlet, and having a filtered inlet fluidly connected to the portion of the discharge line and a filtered outlet, wherein the valve member further includes a flow through passage configured to allow fluid flow through the valve member and the portion of the supply line
• wherein the valve member is configured to allow a first fluid flow from the unfiltered inlet to the unfiltered outlet and from the unfiltered outlet to a filter, and allow a second fluid flow from the filter to the filtered inlet and from the filtered inlet to the filtered outlet when the valve member is in an open position,
• wherein when the valve is in a closed position, fluid flows through the flow through passage to flow through the portion of the discharge line, and fluid does not flow through the unfiltered inlet or the filtered inlet to reach the portion of the discharge line, and
• wherein the first fluid flow and the second fluid flow do not inter-mix.
