Thebelofoe lokela ho etsa bonnete ba hore litlhoko tsa tsamaiso ea lipeipi bakeng sa valve li etsoa ka mokhoa o sireletsehileng le ka mokhoa o ts'eptjoang e le karolo ea bohlokoa ea tsamaiso. Ka hona, moralo oa valve o tlameha ho khotsofatsa litlhoko tsohle tsa valve mabapi le ts'ebetso, tlhahiso, ho kenya, le tlhokomelo hammoho le khatello, mocheso, kutu, thepa ea mokelikeli oa mochine o sebetsang, le ts'ebetso, tlhahiso le tlhokomelo.

Bakeng sa abelofomoralo hore o etsoe ka nepo, o tlameha ho hlakisa lintlha tse fanoeng tsa tekheniki, kapa "kenyelletso ea moralo".

Lintlha tsa motheo tsa horebelofo's "design input" e tlameha ho ba le:

tshebetso kapa mofuta wa valve

maemo a tlase a kgatello ya mosebetsi

leqephe la mosebetsi la boemo bo mahareng

Litšobotsi tsa 'mele le lik'hemik'hale tsa seaplane (corrosivity, ho cha, chefo, boemo ba taba, joalo-joalo)

Molemo ka lebitso

Boholo ba sebopeho

Mokhoa oa ho hokahanya le pipeline

Tsela eo valve e sebetsang ka eona (manual, gear, worm, motlakase, pneumatic, hydraulic, joalo-joalo)

Lintlha tse latelang le litlhaloso tsa tekheniki li lokela ho utloisisoa pele ho nts'etsopele ts'ebetso ea valve le litšoantšo tsa kaho:

Sekhahla sa phallo ea valve le coefficient ea ho hanyetsa mokelikeli

sekhahla le nako ea ho bula le ho koala valve

thepa ea matla a ho khanna (AC kapa DC, voltage, khatello ea moea, joalo-joalo)

Maemo a ho sebetsa le a tlhokomelo ea li-valve (joalo ka hore na ha li phatlohe kapa li maemong a leholimo a tropike, jj.)
