A valve adapted to control liquid pressure by sliding within a valve housing a bottomed tubular valve closure member having a porous peripheral wall. The pores are subjected to reverse flush by moving the valve closure member to a closed position and also by closing an open end of the valve closure member. The valve housing includes a passage for discharging the liquid from the valve at times of the reverse flush.
A control valve comprising: a valve housing defining an interior space; a partition defining an opening and dividing said interior space of said valve housing into an upstream space and a downstream space; a valve closure member slidably mounted in said opening and including a closed end reciprocable within said downstream space between an uppermost position and said partition, and a peripheral wall integral with said closed end defining a plurality of pores, and an open end opposite said closed end being reciprocable only within said upstream space betw...
