Hlola amavalvu, eyaziwa nangokuthiamavalvu wokuhlolanofana amavalvu wokuhlola, asetjenziselwa ukukhandela ukubuyela emuva kwemidiya ephayiphini. Ivalvu yeenyawo yokudosa ngaphandle kwepompo yamanzi nayo ingokwesigaba samavalvu wokuhlola. Iingcenye ezivulako nezivalako zithembele ekugelezeni namandla we-medium ukuvula nofana ukuvala ngokwawo, ukwenzela bona i-medium ingagelezi emuva. Amavalvu wokuhlola angasesigabeni samavalvu azenzekelayo, asetjenziswa khulu emaphayiphini lapho umkhathi ugelezela khona ngendlela eyodwa, begodu avumela umtjhini bona ugeleze ngendlela eyodwa ukukhandela iingozi.
Ngokuya ngesakhiwo, i-valve yokuhlola ingahlukaniswa yaba mihlobo emithathu: i-valve yokuhlola yokuphakamisa,ivalvu yokuhlola yokujingakunyeivalvu yokuhlola ivivane. Amavalvu wokuhlola aphakamisako angahlukaniswa abe mavalvu wokuhlola ajame ngqo kanye namavalvu wokuhlola avundlileko.
Kunemihlobo emithathuamavalvu wokuhlola ajikijela: amavalvu wokuhlola ane-lobe eyodwa, amavalvu wokuhlola anama-flap amabili kanye namavalvu wokuhlola anama-flap amanengi.
Ivalvu yokuhlola ye-butterfly yivalvu yokuhlola eqondileko, begodu ivalvu yokuhlola engenhla ingahlukaniswa yaba mihlobo emithathu: ivalvu yokuhlola yokuxhumana eneentambo, ivalvu yokuhlola yokuxhumana ye-flange kanye nevalvu yokuhlola ehlanganisiweko.
Kufanele kutjhejwe izinto ezilandelako ekufakweni kwamavalvu wokuhlola:
1. Ungenziivalvu yokuhlolaithwale ubudisi ngaphakathi kwepayipi, begodu i-valve yokuhlola ekulu kufanele isekelwe ngokuzijamela ukwenzela bona ingathintwa mfutho okhiqizwa yiphayiphi.
2. Ngesikhathi sokufaka, tjheja indlela yokugeleza okuphakathi kufanele ihambisane nendlela yomcibisholo ovotelwe mzimba wevalvu.
3. Ivalvu yokuhlola i-flap ephakamileko kufanele ifakwe ephayiphini ejame ngqo.
4. Ivalvu yokuhlola i-flap evundlileko yokuphakamisa kufanele ifakwe ephayiphini evundlileko. Khuyini ivalvu yokuhlola eqondileko? Amavalvu wokuhlola athe ngqo asetjenziswa khulu eenhlelweni lapho kutlhogeka khona ukukhandela ukubuyela emuva kwemidiya, njengokuphuma kwepompo, ukuphela kokugcwalisa amanzi atjhisako, kanye nokuphela kokudonsa kwepompo ye-centrifugal. Umsebenzi wayo kukukhandela imiphumela engaba khona ngokubuyela emuva kwe-medium, isibonelo, nangabe indawo yokuphuma yepompo ayifakwanga i-valve yokuhlola ejame ngqo, amanzi abuya ngejubane elikhulu azokubanga umthelela omkhulu ku-impeller yepompo lokha ipompo nayima msinyana; Nangabe i-valve yokuhlola ejame ngqo (i-foot valve) ayifakiwe ekupheleni kokudonsa kwepompo ye-centrifugal, ipompo itlhoga ukuzaliswa ngaso soke isikhathi ipompo ivuliwe.
Imibuzo eminengi, ungathintana ne-TWS VALVE ekhiqiza ngeposiivalvu yevivane ehlala phasi, ivalvu yesango, i-valve yokuhlola, i-Y-strainer, njll.
