1. Ni a bɛ fɔ ka ɲɛsin valve bololabɔli ma, a bɛ jɛya ka tɛmɛn ka pibiliki kofɔ. O ye yɔrɔ ye min bɛ valve ni pipeline siri ɲɔgɔn na, wa a jɔyɔrɔ ka bon kosɛbɛ switch (switch) kɔlɔsili jɔyɔrɔ la. Ni a bɛ kɛ cogo la min bɛ bɛn, minɛn in ka ladɛrɛsi ka kan ka kɛ ni fɛn kelen ye min bɛ kɛ ka ɲɛ ani a cogoya ɲɛfɔcogo ɲuman. O bɛ nɔ bila tigitigi valve bɛɛ ka lakana ni a ka baara kɛcogo la.
2. A fɔlɔ, an ka kuma jɛɲɔgɔnya kan min bɛ sɔrɔ valve handweel ni valve cɛ. A ka c’a la, valve (datugulan) ɲɔgɔndan bɛ welding (sɔgɔ) walima flange (flan) ni thread connection (flan ni ɲɔgɔn cɛ) de wajibiya. Valve fittings kɛrɛnkɛrɛnnen dɔw ani brackets fana mago bɛ cɛmancɛ la. Valvew ni pibilikiw fana bɛ se ka faamuya tiɲɛ yɛrɛ la. U bɛ kɛ pibiliki belebelebaw kan, wa a ka c’a la, u bɛ welding de wajibiya. Fɛɛrɛ gɛlɛnw ka kan ka ta walasa ka a jira ko a cɛmancɛ ni a funteni ka bon. Ni an ye valvew ni pipelines (bolifɛnw) jateminɛ, o ye ko degun seko bɛ mara bolola-wotoro fɛ.
3. Valve handweel jɔyɔrɔ ka bon lakana la, wa valve farikolo ka fɛn bɛ se ka welda caman na, o fana bɛ bololafɛnw ka fɛn dilanni de wajibiya ka kɛ inox walima nɛgɛ ye, nɛgɛ min bɛ kɛ, ani sanni ka kɛ ka kɛɲɛ ni ko yɛrɛ ye.
4. Ko minnu mago bɛ jateminɛ na, olu ye jɔli ni fɛn dilannenw sugandili ye cogo bɛnnen na.
5. Future Outlook: Intelligent valve handheels yiriwali .
Fɛnw ka ɛntɛrinɛti yiriwali n’u ka fɛɛrɛbɔ hakilitigiw fɛ, a jirala ko valve handheels dilanni bɛna kɛ hakilitigi ye kosɛbɛ don nataw la. Sensɔrɔlanw ni kunnafoniw sɔrɔli minɛnw farali bɛna kɛ sababu ye ka bololabaarakɛlaw ka baara kɛ ni hakili ye, wa hali yɔrɔjan baara ni otomatiki ladilanni bɛ se ka kɛ. Future ka valve handwheel bɛ se ka kɛ mechanical control minɛn dɔrɔn ye tugun, nka a bɛ se ka kɛ control unit intelligent ye min bɛ don ɲɔgɔn na kosɛbɛ ni nizɛri sitɛmu ye.
