Valve ea heke ea tšepe e entsoeng ka maiketsetso ke mofuta oa valve e sebelisoang hangata lits'ebetsong tsa khatello e phahameng le mocheso o phahameng. E etselitsoe ho laola phallo ea mokelikeli ka har'a phaephe ka ho bula le ho koala heke (wedge kapa disk). Kaho ea tšepe e entsoeng ka maiketsetso e fana ka matla le ho tšoarella, e leng se etsang hore e lokele libaka tse thata tsa indasteri. Livalve tsena li sebelisoa hangata liindastering tse kang oli le khase, petrochemical le tlhahiso ea motlakase.
1. Matla le ho tiea ho hoholo: Thepa ea 'mele oa valve ea valve ea heke ea tšepe e entsoeng ka tšepe ke tšepe ea boleng bo holimo ea tšepe e nang le khabone e tlase le tšepe ea alloy, e hlahisoang ka ts'ebetso ea ho betla 'me e na le matla le ho tiea ho hoholo.
2. Ho hanyetsa ho robeha hantle: 'Mele oa valve o na le bothata bo phahameng le ho hanyetsa ho robeha hantle, 'me o ka hanela ho robeha ha lehlabathe, slurry le mecha e meng ea phatlalatso.
3. Khanyetso e nyane ea mokelikeli: Bokaholimo ba ho koala ha valve ea heke ea tšepe e entsoeng ka tšepe bo boreleli, khanyetso ea mokelikeli e nyane, 'me ha ho na ho senngoa ha seretse kapa ho thijoa ho tla etsahala.
4. Tlhokomelo e bonolo: likarolo tse koalang (lipoleiti tsa heke) thellela le khohlano li etsa hore tlhokomelo e be bonolo haholoanyane.
5. Tšebeliso e pharaletseng: Li-valve tsa heke tsa tšepe tse entsoeng ka tšepe li ka sebelisoa mefuteng e fapaneng ea liphaephe tse nang le bokhoni bo pharaletseng ba phallo.
