Valve yamagetsi yamagetsi imayikidwa pa payipi ndipo imalumikizana mwachindunji ndi sing'anga yogwirira ntchito, ndipo imakhudzidwa ndi zovuta zogwirira ntchito monga kutentha kwakukulu, kuthamanga kwambiri, kuphulika ndi kugwedezeka kwa nthawi yaitali. Choncho, kusankha khalidwe la valavu yoyang'anira kumakhudza kwambiri kayendetsedwe ka kayendetsedwe kake. Choncho, kusankha koyenera ndi koyenera ndi kukhazikitsa valavu yoyendetsa ndikofunikira kwambiri.
1. Valavu yoyendetsera magetsi iyenera kufufuzidwa ndikutsimikiziridwa poyamba, ndikuyika payipi itatha kutsukidwa.
2. Kuyika kwa valve yoyendetsera magetsi kumayenera kukhala kosavuta kuti agwire ntchito ndi kukonzanso, kuti ogwira ntchito azitha kukonza ndikugwira ntchito, ndipo nsanja iyenera kukhazikitsidwa ngati kuli kofunikira.
3. Pamene valve yoyendetsa magetsi imayikidwa mu malo ogwedezeka, njira zotsutsana ndi kugwedezeka ziyenera kuganiziridwa.
4. Vavu yoyang'anira magetsi iyenera kuyikidwa molunjika ndi yowongoka paipi yopingasa. Vavu yoyang'anira yokhala ndi mainchesi a DN≥50 iyenera kukhala ndi zothandizira zokhazikika papaipi isanachitike komanso pambuyo pake.
5. Kwa ma valve oyendetsa magetsi opanda ma valve positioner, ndi bwino kukhazikitsa kachidutswa kakang'ono kamene kamasonyeza chizindikiro chowongolera pamutu wa membrane.
6. Payenera kukhala malo okwanira kumtunda ndi kumunsi kwa valavu yoyendetsa magetsi kuti achotse makina oyendetsa, valve trim, ndi flange yapansi ndi pulagi ya valve panthawi yokonza.
7. Malo opangira magetsi oyendetsa magetsi ayenera kukwaniritsa zofunikira za ndondomekoyi, ndipo ayenera kukhala pafupi ndi chida choyamba chowonetsera chokhudzana ndi icho, kuti chida choyamba chiziwoneka pamene valve yodutsa ikugwiritsidwa ntchito pamanja;
8. Valavu yoyendetsera iyenera kukonzedwa pansi kapena nsanja ndi yabwino kuti igwire ntchito ndi kukonza.
9. Vavu yoyang'anira iyenera kuyikidwa molunjika komanso molunjika paipi yopingasa. Pazifukwa zapadera, imatha kukhazikitsidwa mozungulira kapena mozungulira, koma iyenera kuthandizidwa;
10. Pamene gulu la valve loyendetsa (kuphatikizapo valve yoyendetsera, valve bypass, valve shut-off ndi drain valve) imayikidwa vertically, valve yoyendetsera iyenera kuikidwa pansi pa chodutsa. Mavavu owongolera okhala ndi mainchesi osakwana 25mm amathanso kukhazikitsidwa pamwamba panjira.
