Iivalvukufuneka baqinisekise ukuba iimfuno zenkqubo yepayipi yevalvu zenziwa ngokukhuselekileyo nangokuthembekileyo njengenxalenye ebalulekileyo yenkqubo. Ke ngoko, uyilo lwevalvu kufuneka luhlangabezane nazo zonke iimfuno zevalvu ngokwendlela yokusebenza, ukwenziwa, ukufakelwa, kunye nokugcinwa kunye noxinzelelo, ubushushu, ukugqwala, iipropati zolwelo lwesixhobo sokusebenza, kunye nendlela yokusebenza, ukwenziwa, kunye nokugcinwa.

Yeivalvuuyilo ukuze lwenziwe ngokufanelekileyo, kufuneka luchaze idatha yobugcisa enikiweyo, okanye "igalelo loyilo".

Ulwazi olusisiseko oluthiivalvu"Igalelo loyilo" kufuneka libe nalo:

umsebenzi okanye uhlobo lwevalvu

amanqanaba aphantsi oxinzelelo lomsebenzi

iphepha lokusebenzela eliphakathi

Iimpawu zomzimba nezekhemikhali zesixhobo (ukubola, ukutsha, ubuthi, imeko yezinto, njl.njl.)

Ilungile ngegama

Ubungakanani besakhiwo

Uhlobo loqhagamshelwano nombhobho

Indlela esebenza ngayo ivalvu (ngesandla, ngegiya, ngemibungu, ngombane, ngepneumatic, ngehydraulic, njl.njl.)

Iinkcukacha ezilandelayo kunye neenkcukacha zobugcisa kufuneka ziqondwe ngaphambi kokuba kuphuhliswe inkqubo yevalvu kunye nemizobo yokwakha:

Izinga lokuhamba kwevalvu kunye ne-coefficient yokumelana nolwelo

izinga kunye nobude bokuvulwa nokuvalwa kwevalvu

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

Iimeko zokusebenza nokugcinwa kweevalvu (ezifana nokuba azinakuqhuma okanye zikwimozulu eshushu, njl.njl.)

Imida yoBukhulu bangaphandle

Ubunzima obuphezulu

iimfuno zenyikima

Inkqubo yoYilo lweeValve

Ucwangciso loyilo nophuhliso

inqanaba lophuhliso loyilo

Imisebenzi yokuphonononga, ukuqinisekisa, kunye nokuqinisekisa efanelekileyo kwisigaba ngasinye soyilo nophuhliso

Amagunya kunye neembopheleleko kuYilo noPhuhliso

igalelo loyilo nophuhliso

Iimfuneko Zokusebenza Nezokusebenza

Imigaqo kunye neemfuno zomthetho zokusetyenziswa

Ulwazi olufunyenwe kwiindlela zangaphambili nezinxulumene nazo

Imiqathango eyongezelelweyo yophuhliso loyilo

Imveliso yoyilo nophuhliso

ukuhlangabezana neemfuno zokufaka uyilo nophuhliso

Nika idatha efanelekileyo yokuthenga, ukuvelisa, kunye nokubonelela ngeenkonzo.

Cacisa okanye ukhankanye iimfuno zokwamkelwa kwemveliso.

ichaza iimpawu zemveliso ezifunekayo ukuze isetyenziswe ngokukhuselekileyo nangokufanelekileyo.
