4. Aragtida shaqada
Hubi waalka si otomaatig ah ayuu u furmaa oo xiraa saxanka si looga hortago socodka dhexdhexaadka ah ee socodka dhexdhexaadka ah.
5. Heerarka valve ee lagu dabaqi karo laakiin aan ku xaddidnayn:
(1) API 6D-2002 （2） ASME B16.5-2003
(3) ASME B16.10-2000 (4) API 598-2004

6. Kaydinta & Dayactirka & Rakibaadda & Hawlgalka
6.1 Waalka waa in lagu kaydiyaa qol qallalan oo hawo fiican leh.
6.2 Waa in si joogto ah loo baaro oo loo nadiifiyaa Valfyada ku jira kaydinta muddada dheer, gaar ahaan wajiga fadhiga si looga hortago in ay waxyeelo soo gaadho, wajiga fadhigana waa in lagu dahaadhaa miridh ka ilaaliya saliidda.
6.3 Calaamadaynta Valve waa in la hubiyaa si loo waafajiyo isticmaalka.
6.4 Godka Valve iyo dusha daboolida waa in la hubiyaa ka hor inta aan la rakibin oo ka saar wasakh haddii ay jirto.
6.5 Jihada fallaadha waa inay la mid noqotaa jihada socodka.
6.6 Qaadista valve hubinta saxanka toosan waa in si toosan loogu rakibaa dhuumaha. Qaadista waalka hubinta saxanka jiifka ah waa in lagu rakibaa si toos ah dhuumaha.
6.7 Gariirka waa in la hubiyaa iyo isbedelka cadaadiska dhexdhexaadka ah ee dhuumaha waa in la ogaadaa si looga hortago saameynta biyaha.

8. 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.
