Ivalve yebhola yomoyaundoqo ujikeleziswa nokuba uvule okanye uvale ivalve, ngokuxhomekeke kwimeko.
Izitshixo zevalve yebhola yomoya zisetyenziswa kumashishini amaninzi awohlukeneyo kuba zikhaphukhaphu, zincinci ngokobukhulu, kwaye zinokulungiswa zibe nedayamitha enkulu.
Kwakhona banokutywinwa okuthembekileyo, isakhiwo esilula, kwaye kulula ukusigcina.

Imibhobho ngokuqhelekileyo isebenzisa i-pneumaticiivalve zebholaukusasaza ngokukhawuleza kwaye utshintshe indlela yokuhamba kwendlela. Ivalve entsha ebizwa ngokuba yi-pneumatic ball valve ibonelela ngezi zibonelelo zilandelayo:

1. Ngenxa yokuba irhasi ingumthombo wamandla wevalve yebhola yepneumatic, uxinzelelo luphakathi kwe-0.2 kunye ne-0.8 MPa, ebonwa njengekhuselekile.

2. Uluhlu olubanzi lwezicelo; ingasetyenziselwa kwi-vacuum ephezulu kunye neemeko zoxinzelelo oluphezulu; I-diameter isuka kwincinci ukuya kwiimilimitha ezininzi, ezinkulu ukuya kwiimitha ezininzi.

3. Kulula ukuyisebenzisa, ivula kwaye ivale ngokukhawuleza, kwaye ivumela ulawulo lomgama omde olufanelekileyo ngokujikeleza nje i-90 degrees ukusuka ekuvuleni ngokupheleleyo ukuya kuvaliwe ngokupheleleyo.

4. Ukuxhatshazwa kwamanzi kuncinci, kwaye inxalenye yombhobho yobude obufanayo inomlinganiselo ofanayo wokumelana.

5. Kulula ukuqhawula kunye nokutshintsha ngenxa yesakhiwo esisisiseko sevalve yebhola ye-pneumatic, iringi yokutywina eshukumayo, kunye nokugcinwa lula.

6. Umphezulu wokutywina wesihlalo sebhola kunye nevalve zigqunyiwe ukusuka kwindawo ephakathi nokuba ivalve ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo, ngoko ke xa isiphakathi sidlula, ayisayi kukhukulisa umphezulu wokutywina.

7. Iivalve yebholaUmphezulu wokutywina wenziwa ngeplastiki edumileyo eneempawu zokutywina ezilungileyo esele isetyenziswe kakhulu kwiinkqubo zokufunxa. Iqinile kwaye ithembekile.

8.Ukuba i-valve yebhola ye-pneumatic ivuza, ngokuchasene neenkqubo ze-hydraulic okanye zombane, igesi inokukhutshwa ngokuthe ngqo, enezinga eliphezulu lokhuseleko kwaye ayilimazi indalo.
