1. Kuzunguza flange kumuyoboro hanyuma ukonje kubushyuhe bwibidukikije mbere yo gushiraho valve kuri flange.Bitabaye ibyo, ubushyuhe bwo hejuru buterwa no gusudira bizagira ingaruka kumikorere yintebe yoroshye.
2. Impande za flanges zasuditswe zigomba guhindurwa kugirango zibe hejuru kugirango hirindwe kwangirika kwintebe yoroshye mugihe cyo gushyiramo valve.Ubuso bwa flange bugomba kuba butarangwamo rwose kwangirika no guhindagurika, kuvanaho umwanda wose, umukungugu nibintu byamahanga, kandi wirinde kumeneka kwamazi ya valve na Imigaragarire.
3. Sukura flange hamwe nu mwobo wimbere wumuyoboro kugirango ukureho burundu sputter, umunzani nindi mibiri yamahanga yasizwe no gusudira.
4. Mugihe ushyira imiyoboro hagati ya valve, guhuza neza hagati yumurongo wamazi wo hejuru no hepfo ni ngombwa mugukora nta kibazo. Ingingo ya centre idahwitse yerekanwe kumashusho 1 igomba kwirindwa.
5. Mugihe ushyiraho valve, shyira ahabigenewe munsi yumuringa murwego rumwe kugirango ugire uruhare runini, hanyuma uhindure intera iri hagati ya flanges kugeza impande zombi zumubiri wa valve ziri hagati ya mm 6-10. Wibuke ko valve ishobora gufungurwa gusa kuva kumwanya ufunze kugeza kumwanya wa 10 °.
6. Shyiramo ibice bibiri mumurongo wo hasi wo kuyobora wa valve hanyuma ushyire witonze kugirango ubuso bwa flange butangiza intebe yoroshye.6.(reba ishusho ya 2)
7. Noneho shyiramo andi abiri ya bolts mumurongo uyobora hejuru ya valve, urebe neza hagati yikibanza hagati ya pipe na valve.
8. Fungura valve inshuro eshatu kugirango urebe niba guhuza hagati ya plaque na flange bitagenda neza.
9. Kuraho imyanya ihagaze hanyuma ushireho ibihindizo byose bikikije umubiri muguhinduranya diagonal (reba Ishusho 3 na 4) kugeza flange ikora kumubiri.
10. Tanga inkunga ya valve mugihe ushyizeho actuator kugirango wirinde kugoreka ijosi rya valve no kugabanya ubushyamirane hagati ya valve na pipe.
11. Ntukandagire ku ijosi rya valve cyangwa intoki.
12. Ntugashyire DN350 cyangwa nini nini hejuru.
13. Ntugashyireho ikinyugunyugu kinyugunyugu kuri cheque cyangwa pompe kuko ibyo bishobora guteza ibyangiritse iyo uhuye na plaque.
14. Ntugashyireho valve kuruhande rwo hepfo yinkokora no gukanda, cyangwa kalibatifike mugihe igipimo cyimigezi gihindutse.Muri iki gihe, birasabwa gushiraho valve intera yikubye inshuro 10 diameter nominal ya valve.
15. Kwishyiriraho valve bigomba kuzirikana disiki izagira umuvuduko nigitutu mugihe cyo kohereza amazi.
