An xampl of th most popula mthod of constant flo contol ith a ndl valv and flo contoll is xplaind h.

Th flo changs hn th pssu applid to th valv changs. Thfo, a pssu gulato is povidd in th pcding stag as shon in Fig. A to mak th pssu applid to th valv constant, thby obtaining constant flo.

In that cas, a vaiabl sconday pssu (outlt-sid pssu: load pssu) typ flo contoll is usd to contol flo accoding to th flo sht shon in Fig.. This flo sht is complt ith spct to pssu chang, and is usd basically fo ou gas mixing uipmnt. Th pimay-sid pssu is contolld by a gulato, and th flo contoll immun to pssu changs on th sconday sid nabls flo contol f of th influnc of th pimay and sconday pssu.

Thfo, it is ncssay to slct svic conditions as clos to th status (A) as possibl. KOFLO manufactus valvs individually to nsu thy match th svic conditions.
