Waalka waa aalad lagu xakameeyo socodka, cadaadiska, iyo jihada dareeraha.Dheecaanka la xakameeyey wuxuu noqon karaa dareere, gaas, isku-dar gaas- dareere ah, ama isku-dar dareere adag.Valve sida caadiga ah by jirka valve, daboolka, kursiga, qaybo furan oo dhow, habka wadista, shaabadeynta iyo xirmooyinka, iyo wixii la mid ah.Shaqada xakamaynta ee waalka waxay ku xiran tahay habka wadista ama dareeraha si loo kaxeeyo qaadista, silbashada, lulida ama wareega wareega qaybaha furitaanka iyo xidhitaanka si loo beddelo cabbirka aagga orodka.

Valves waxay leeyihiin adeegsiyo kala duwan waxayna si dhow ula xiriiraan nolol maalmeedka dadka, sida qasabadaha tuubooyinka biyaha iyo cadaadiska yareeya shalalka gaaska dareeraha ah.Valves sidoo kale waa qaybaha lagama maarmaanka u ah qalabyada kala duwan ee makaanik sida matoorada gubashada gudaha, matoorada uumiga, kombaresarada, bambooyin, dhaq-dhaqaaqa sambabada, baabuurta nidaamka hawo-biyoodka, maraakiibta iyo diyaaradaha.

Kahor 2,000 BC, Shiinuhu waxay isticmaaleen tuubooyinka bamboo iyo tuubooyinka gufyada ee dhuumaha biyaha, irdaha biyaha ee kanaalka waraabka, iyo saxannada hubinta valves ee dhalaalidda hooska leh horumarinta tignoolajiyada dhalaalidda iyo mashiinnada haydarooliga, naxaasta iyo furayaasha rasaasta ayaa ka soo muuqday Yurub.Markii la hirgeliyay kuleyliyaha, 1681 waxay soo bandhigtay galka badbaadada nooca dubbe ee kabaalka.1769 iyo hubinta valves waxay ahaayeen valves-yada aasaasiga ah ilaa mashiinka uumiga Watt.Abuuritaanka mishiinka uumiga ayaa keenay waalka galay beerta warshadaha farsamada.Marka lagu daro furka, gargaarka iyo hubinta valves-ka ee loo isticmaalo matoorada uumiga Watt, baallooyinka balanbaalista ayaa loo isticmaalaa si loo habeeyo socodka.Kordhinta qulqulka uumiga iyo cadaadiska, isticmaalka qalabka furka si loo xakameeyo qaadashada uumiga iyo qiiqa matoorka uumiga ma dabooli karo baahida, sidaas darteed waxaa jira valve slide ah.

Kahor iyo ka dib 1840, waxaa jiray valves globe oo leh afkoda dunta iyo alxanka alxanka leh afkoda Trapezoidal, taas oo ahayd horumar weyn oo horumarinta waalka.Muuqaalka labadan nooc ee valves ma aha oo kaliya inay ku qanacsan yihiin baahida sii kordheysa ee cadaadiska iyo heerkulka warshadaha kala duwan ee wakhtigaas, laakiin sidoo kale waxay ku qanacsan yihiin baahida nidaamka socodka.Tan iyo markaas, iyada oo horumarinta warshadaha tamarta korontada, warshadaha batroolka, warshadaha kiimikada iyo warshadaha dhismaha maraakiibta, dhammaan noocyada kala duwan ee cadaadiska sare iyo kuwa dhexdhexaadka ah ayaa si degdeg ah loo sameeyay.

Ka dib Dagaalkii Labaad ee Adduunka, iyadoo ay ugu wacan tahay horumarinta qalabka polymer, alaabta saliidda, birta aan la taaban karin iyo kobalt-ku-saleysan carbide, Old Plug Valve iyo balastar galka ayaa loo adeegsaday codsiyada cusub, valve valve iyo diaphragm valve ayaa si degdeg ah loo sameeyay.Gawaarida Globe, valves gate iyo valves kale oo kala duwan iyo tayada kordhay.Warshadaha wax soo saarka Valve ayaa si tartiib tartiib ah u noqday qayb muhiim ah oo ka mid ah warshadaha mishiinada.Valve sida waafaqsan isticmaalka shaqada waxaa loo qaybin karaa block valve, valve control, check valve, valve leexinta, valve badbaadada, waalka ujeedo badan 6 qaybood.
