PCT No. PCT/AU96/00728 Sec. 371 Date May 13, 1998 Sec. 102(e) Date May 13, 1998 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/18026 PCT Pub. Date May 22, 1997The present invention relates to valve constructions which allows two different flow rates to pass through said valve, whether by two separate control signals or by one control signal and the second flow rate being attained automatically or inherently after the first flow rate has passed through the valve. The invention also includes a filter material cleaning system and a method of operating a filter material cleaning system which utilizes this valve but which helps to prevent the factors which would cause the re-deposition of the filtered particulate material whether onto the row of filter bags being cleaned, and or an adjacent row to the row being cleaned or two adjacent rows to the row being cleaned.
