The outflow passage switching valve 6 also turns 9 while turning clockwise by 5 degrees.
By turning 0 degrees counterclockwise, the opening / closing valves 13 and 14 of the inflow passage switching valve 5 close the inlets / outlets 8 and 10, and the inlets / outlets 7 and 9 communicate with each other, whereby the fluid from the inlet / outlet 7 is filtered. The fluid that has reached the inside of the filter 23 of No. 3 and the foreign matter has been removed reaches the predetermined fluid use location from the outlet 27 of the outflow passage switching valve 6, and functions as a normal strainer.

ができる。Further, when the inflow passage switching valve 5 is rotated 90 degrees counterclockwise from the state shown in FIG.
Since 0 is communicated and the inlets / outlets 7 and 8 and 9 are not communicated with each other, the fluid from the inlet / outlet 7 does not reach the filtering portion 3 and the outflow passage 4 but is directly communicated from the communication hole 10 which is an inlet / outlet to the outside of the system. As a result, the foreign matter between the fluid source (not shown) connected to the inlet / outlet 7 and the inflow passage 2 can be directly excluded from the system.
