Iivalvekufuneka iqinisekise ukuba iimfuno zesixokelelwano semibhobho yesivalo ziqhutywa ngokukhuselekileyo nangokuxhomekeke njengenxalenye edityanisiweyo yesixokelelwano.Ke ngoko, uyilo lwevalvu kufuneka lwanelise zonke iimfuno zevalve ngokwemigaqo yokusebenza, ukwenziwa, ukufakela, kunye nokugcinwa kunye noxinzelelo, ubushushu, ukubola, iipropathi zolwelo lwendlela yokusebenza, kunye nokusebenza, ukwenziwa kunye nokugcinwa.

Yeivalveuyilo kufuneka lwenziwe ngokufanelekileyo, kufuneka lucacise idatha enikiweyo yobugcisa, okanye "igalelo loyilo".

Ulwazi olusisiseko ukuba iivalve"Igalelo loyilo" kufuneka libe nalo:

umsebenzi okanye uhlobo lwevalvu

amanqanaba aphantsi oxinzelelo lomsebenzi

Iphepha lomsebenzi eliphakathi

Iimpawu zomzimba kunye neekhemikhali zomthombo (ukonakala, ukutsha, ubutyhefu, imeko yento, njl.njl.)

Ulungile ngegama

Ubungakanani besakhiwo

Ifomu yokudibanisa kunye nombhobho

Indlela esebenza ngayo ivalve (i-manual, gear, worm, umbane, i-pneumatic, i-hydraulic, njl.

Ezi nkcukacha zilandelayo kunye neenkcukacha zobugcisa kufuneka zibanjwe phambi kokuphuhliswa kwenkqubo yevalve kunye nemizobo yokwakha:

Isantya sokuhamba kwevalve kunye ne-coefficient yokumelana nolwelo

umlinganiselo kunye nobude bexesha lokuvula nokuvalwa kwevalvu

Iipropati zamandla okuqhuba (i-AC okanye i-DC, i-voltage, uxinzelelo lomoya, njl.)

Iimeko zokusebenza kunye nokugcinwa kweevalvu (ezifana nokuba azikwazi ukuqhuma okanye kwiimozulu zetropikhi, njl.)

Imida yoMda waNgaphandle

Ubunzima obukhulu

iimfuno zenyikima

Inkqubo yoYilo lweValve

Isicwangciso soyilo nophuhliso

inqanaba lophuhliso loyilo

Imisebenzi yokuphononongwa, ukuqinisekiswa, kunye nokuqinisekiswa okufanelekileyo kuyilo ngalunye kunye nesigaba sophuhliso

Abasemagunyeni kunye noxanduva kuYilo noPhuhliso

igalelo kuyilo nophuhliso

IiMfuno zokuSebenza kunye nokuSebenza

Imimiselo kunye neemfuno ezisemthethweni zokusetyenziswa

Ulwazi oluvela kuyilo lwangaphambili, olunxulumeneyo

Iimeko ezongezelelweyo zophuhliso loyilo

Imveliso yoyilo kunye nophuhliso

ukuzalisekisa iimfuno zoyilo kunye nophuhliso lwegalelo

Nika idatha efanelekileyo yokuthenga, ukuvelisa, kunye nokubonelela ngeenkonzo.

Cacisa okanye ukhankanye iimfuno zokwamkelwa kwemveliso.

ichaza iimpawu zemveliso efunekayo ukuze isetyenziswe ngokukhuselekileyo nangempumelelo.
