Pneumatic control valve handwheel baara ka bon kosɛbɛ. Bololabaara kɛcogo bɛ kɛ ka fara ɲɛnabɔli-minɛn kan, wa a baara kunbabaw ye ninnu ye:
1 Ni fiɲɛ bɔyɔrɔ taamasiɲɛ walima kuran taamasiɲɛ ma ɲɛ, walima ni baarakɛminɛn yɔrɔ kolomaw (i n’a fɔ dawolo, foronto, sigilan, fɛn wɛrɛw cicogo, a ɲɔgɔnnaw) bɛ tiɲɛ, otomatik baara ka kan ka Changé ka kɛ bololabaara ye, ani bolokɔfɛfɛn bɛ se ka kɛ. Fɛɛrɛ bɛ ka taa a fɛ ka ɲɛnabɔli-minɛn ka ɲɛnabɔli baara mara.
2 Bololabaarakɛla bɛ se ka kɛ dan ye fana ka ɲɛsin valve stroke labɛnni ma. (dantigɛli baarakɛcogo) .
3 Bololabaarakɛlaw ka fɛɛrɛ bɛ se ka labɛn ka ɲɛ ka ɲɛsin a labɛnni ma. Ni bypass farala regulating valve kan, wari bilali ka kan ka kɛ.
A musaka ka bon, a yɔrɔ ka bon, a musaka ka bon ni a kalifa ka bon walima ni nɛgɛ nafamaw bɛ kɛ. A musaka ka ca-A bɛ nafa sɔrɔ ka baara kɛ ni bololafɛnw ye, waridon musaka walima dugukolo yɔrɔ mana kɛ min o min ye.
Ka fara o kan, ka ɲɛsin diaphragme valves single{0} ma, bolokɔfɛfɛn jɔyɔrɔ n’a kɛcogo (min bɛ kɛ ni fɛnɲɛnamafagalan ye) ye siratigɛ ye. O waati kelen na, daji-walekɛlanw bɛ kɛ yɔrɔ minnu na, olu bɛ kɛ yɔrɔ minnu na, baara degun ka dɔgɔ kosɛbɛ ani dadonko wajibiyalenw man gɛlɛn, wa fanga tɛ bonya kosɛbɛ. O la, a bɛ se ka bolokɔniw sigi senkan k’a ɲɛsin u ma, k’a sɔrɔ u mago tɛ ka baara dilan-Masaw lakanani (n’a ma kɛ kɛrɛnkɛrɛnnenya la), wa a tɛ kɛ tiɲɛ ye ka baara kɛ ni bololanɛgɛw ye. Boliw bɛ baara kɛ caman na double-wale, piston-type actuators kan. Double-Acting valve tɛ ko ye. A wide-kulu fila-Acting valve ye caman na bololanɛgɛ ye min bɛ se ka da wuli ani ka datugu.
