3. Kaydinta & Dayactirka & Rakibaadda & Hawlgalka
3.1 Kaydinta & Dayactirka
3.1.1 Valves waa in lagu kaydiyaa xaalada gudaha.Cidhifyada godka waa in lagu daboolaa fig.
3.1.2 Baadhitaanka iyo nadiifinta wakhtiyeedka ah ayaa loo baahan yahay wakhti dheer alwaaxyada kaydsan, gaar ahaan daboolida nadiifinta dusha sare.Wax dhibaato ah lama ogola.Dahaarka saliidda ayaa la codsadaa si looga fogaado miridhku si loogu farsameeyo dusha sare.
3.1.3 Ku saabsan kaydinta waalka in ka badan 18 bilood, tijaabooyin ayaa loo baahan yahay ka hor inta aan la rakibin waalka oo la diiwaangeliyo natiijada.
3.1.4 Valves waa in si joogto ah loo baaro oo la dayactiro ka dib marka la rakibo.Qodobbada ugu muhiimsan waa sida soo socota:
1) dusha daboolida
2) Dhirta iyo jirida
3) Baakadaha
4) Nadiifinta dusha gudaha ee Jirka iyo Bonnetka.
3.2 Rakibaadda
3.2.1 Dib u hubi calamadaha waalka (Nooca, DN, Rating, Material) kaas oo u hogaansama calaamadaha lagu codsado nidaamka dhuumaha.
3.2.2 Nadiifinta buuxda ee daloolka iyo daboolida dusha sare ayaa la codsadaa ka hor inta aan la rakibin waalka.
3.2.3 Hubi in boolalku ay adag yihiin ka hor inta aan la rakibin.
3.2.4 Hubi in baakadu ay adag tahay ka hor inta aan la rakibin.Si kastaba ha ahaatee, waa inaysan carqaladayn dhaqdhaqaaqa stem.
3.2.5 Goobta Valve waa inay ku habboonaato kormeerka iyo hawlgalka.Horizontal to pipeline ayaa la door bidayaa.Kor u qaad shaagaga gacanta iyo jirida mid taagan.
3.2.6 Qalabka xiritaanka, kuma habboona in lagu rakibo xaalad shaqo oo cadaadis sare leh.Jirriddu waa in laga fogaadaa in ay dhaawacdo.
3.2.7 Waalka alxanka Socket, dareenka ayaa la codsanayaa inta lagu jiro isku xirka valve sida soo socota:
1) Welder waa in la shahaado.
2) Halbeegga habka alxanka waa in uu ahaadaa mid waafaqsan shahaado tayada alxanka qaraabo.
3) Walxaha buuxinta ee xariiqda alxanka, kiimikooyinka iyo waxqabadka farsamada oo ay weheliso daxalka ka hortagga waa inay la mid noqdaan walxaha waalidka.
3.2.8 Ku rakibida Valve waa in ay ka fogaato cadaadiska sare ee lifaaqyada ama tuubooyinka.
3.2.9 Kadib rakibidda, valves waa inay furnaadaan inta lagu jiro tijaabada cadaadiska tuubada.
3.2.10 Taageerada Point: haddii dhuunta ay tahay mid xoogan oo ku filan si ay u taageeraan miisaanka waalka iyo torque hawlgalka, barta taageerada lama codsan.Haddii kale waa loo baahan yahay.
3.2.11 Qaadista: Qaadista taayirrada gacanta looma oggola valves.
3.3 Hawlgalka iyo Isticmaalka
3.3.1 Albaabada albaabadu waa inay si buuxda u furnaadaan ama xidhaan inta lagu jiro isticmaalka si looga fogaado xirashada giraanta iyo dusha saxanka ee ay keento dhexdhexaad xawaare sare leh.Looma dacwayn karo nidaaminta socodka
3.3.2 Taayirrada gacanta waa in lagu beddelaa aaladaha kale si loo furo ama loo xiro furayaasha
3.3.3 Inta lagu jiro heerkulka adeegga la oggol yahay, cadaadiska degdegga ah waa inuu ka hooseeyaa cadaadiska la qiimeeyay marka loo eego ASME B16.34
3.3.4 Wax dhaawac ah ama shaqo joojin ah lama ogola inta lagu jiro gaadiidka waalka, rakibaadda iyo hawlgalka.
3.3.5 Qalabka cabbirka si loo hubiyo socodka aan xasilloonayn ayaa la codsanayaa si loo xakameeyo oo looga takhaluso qodobka burburay si looga fogaado burburka iyo daadinta.
3.3.6 Uumiga qabow wuxuu saameyn doonaa waxqabadka valve, iyo qalabka cabbiraadda waa in la isticmaalo si loo yareeyo heerkulka socodka ama lagu beddelo valve.
3.3.7 Dheecaan is-bari kara, isticmaal qalabka cabbiraadda habboon si loo dammaanad qaado cadaadiska deegaanka iyo shaqada kama badna barta shidista (gaar ahaan ogaysii qorrax ama dabka dibadda).
3.3.8 Haddii ay dhacdo dareere khatar ah, sida walxaha qarxa, gubanaya, sunta, alaabada oksaydhka, waa mamnuuc in la beddelo baakadaha cadaadiska.Si kastaba ha ahaatee, xaalad degdeg ah, laguma talinayo in la beddelo baakadaha cadaadiska (inkasta oo waalka uu leeyahay shaqo noocaas ah).
3.3.9 Hubi in dareeruhu aanu wasakh ahayn, kaas oo saameeya waxqabadka valve, oo aanay ku jirin adkaha adag, haddii kale qalabka cabbiraadda ku habboon waa in la isticmaalo si looga saaro wasakhda iyo adkaha adag, ama lagu beddelo nooc kale oo waalka ah.
3.3.10 Heerkulka shaqada ee lagu dabaqi karo.
| Qalab | Heerkulka | Qalab | Heerkulka |
| WCB | -29～425℃ | WC6 | -29～538℃ |

Fiiro gaar ah: Qofka adeeguhu waa inuu lahaadaa aqoon iyo waayo-aragnimo la xidhiidha valves-ka biyaha xidhidhiyaha albaabka
Xirmooyinka bonnetka waa qaab dhismeedka daboolida biyaha, waxaa laga sooci doonaa hawada halka cadaadiska biyuhu uu gaaro 0.6 ~ 1.0MP si loo dammaanad qaado waxqabadka wanaagsan ee xiritaanka hawada.
5.Dammaanad:
Ka dib markii waalka la geliyo, muddada dammaanadda ee waalka waa 12 bilood, laakiin kama badna 18 bilood ka dib taariikhda dhalmada.Inta lagu jiro muddada dammaanadda, soo-saaruhu waxa uu ku siin doonaa adeeg dayactir ama qalab-hagaajin lacag la'aan ah waxyeelada ay sabab u tahay agabka, shaqada ama burburka waa haddii hawlgalku sax yahay.
