Mwa mitundu yosiyanasiyana ya ma valve,ma valve pachipatandi omwe amagwiritsidwa ntchito kwambiri.Valovu yachipata imatanthawuza valavu yomwe mbale yake yachipata imasunthira molunjika kumtunda wa tchanelo.Amagwiritsidwa ntchito kwambiri podula sing'anga pa payipi, ndiko kuti, kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu.Kawirikawiri, ma valve a pakhomo sangathe kugwiritsidwa ntchito ngati throttling.Itha kugwiritsidwa ntchito pakutentha kwambiri komanso kuthamanga kwambiri, ndipo imatha kugwiritsidwa ntchito pazinthu zosiyanasiyana.Mavavu apazipata nthawi zambiri sagwiritsidwa ntchito m'mapaipi omwe amanyamula matope ndi madzi amadzimadzi.
Valve yachipata ili ndi zabwino izi:
1. Small madzimadzi kukana;
2. Torque yofunikira pakutsegula ndi kutseka ndi yaying'ono;
3. Itha kugwiritsidwa ntchito papaipi yapaintaneti ya mphete pomwe sing'anga imayenda mbali ziwiri, ndiko kunena kuti, njira yolowera sing'angayo siyimatsekeka;
4. Mukatsegula kwathunthu, kukokoloka kwa malo osindikizira ndi sing'anga yogwirira ntchito kumakhala kochepa kwambiri kuposa valve ya globe;
5. Mawonekedwewa ndi ophweka ndipo njira yopangira zinthu ndi yabwino;
6. Kutalika kwa dongosololi ndi kochepa.
Chifukwa ma valve a pakhomo ali ndi ubwino wambiri, amagwiritsidwa ntchito kwambiri.Nthawi zambiri, payipi yokhala ndi kukula kwadzina ≥ DN50 imagwiritsidwa ntchito ngati chipangizo chodula sing'anga, ndipo ngakhale mapaipi ang'onoang'ono (monga DN15~DN40), mavavu ena achipata amasungidwabe.
Ma valve a zipata amakhalanso ndi zovuta zina, makamaka:
1. Miyeso yonse ndi kutalika kwa kutsegula ndi zazikulu, ndipo malo ofunikira oyika nawonso ndi aakulu.
2. Panthawi yotsegulira ndi kutseka, pali mikangano pakati pa malo osindikizira, ndipo kuvala kumakhala kwakukulu, ndipo n'kosavuta kuyambitsa zipsera.
3. Kawirikawiri, ma valve a zipata amakhala ndi awiriawiri osindikizira, zomwe zimapangitsa kuti zikhale zovuta kukonza, kugaya ndi kukonza.
4. Nthawi yotsegula ndi yotseka ndi yaitali.
