Tilmaanta caqliga leh ee palve palve mowqifka

Meelaha valve, sida ugu weyn ee loo yaqaan 'valef', oo ah meelaynta tuubbada ayaa ah sida ugu weyn ee loo adeegsado xakameynta furitaanka ee pneve-ka, kaas oo loo adeegsado in lagu hubiyo in waalka ay si sax ah u joogsan karto si sax ah marka ay gaarto booska. Iyada oo loo marayo kontoroolka saxda ah ee meelaynta tuubbada, hagaajinta saxda ah ee dareeraha waxaa lagu gaari karaa si loo haqabtiro baahiyaha howlaha kala duwan ee warshadaha kala duwan. Boosteejooyinka Valve ayaa loo qaybiyaa meelaha dheeraadka ah ee pneve-ka, oo lagu qaado tuubooyinka tuubbada-bulukeetiga iyo tuubooyinka tuubbada leh ee tuubooyinka xunxun iyadoo loo eegayo qaab-dhismeedkooda. Waxay helayaan seenyaalaha wax soo saarka ee xeer-galeenka ka dibna u adeegso calaamadaha wax soo saarka si loo xakameeyo dareemayaasha lagu xakameeyo valve. Barakaca of stem stem waxaa lagu daadiyaa booska tuubbada tuubbada aaladda farsamada, iyo heerka jagada booska waxaa loo gudbiyaa nidaamka sare iyada oo loo marayo seenyaalaha korantada.

Boosteejooyinka xiisaha badan ee pneumatic waa nooca ugu aasaasiga ah, helitaanka iyo quudinta calaamadaha dib-u-celinta aaladaha farsamada.

Booska vneumatic-pure-puveumatic vneve palve waxay isku daraan tikniyoolajiyada korantada iyo kuwa dheecaanka leh si loo wanaajiyo sax ahaanta iyo dabacsanaanta xakamaynta.
Boos jees-gacmeedka caqliga leh wuxuu soo bandhigayaa tikniyoolajiyadda Micprocessor-ka si loo gaaro otomatiga iyo xakamaynta caqliga leh.
Boosteejooyinka faashaddu waxay door muhiim ah ka ciyaaraan nidaamyada otomatiga warshadaha, gaar ahaan xaaladaha ay saxeexyada saxda ah ee qulqulka dareeraha loo baahan yahay, sida kiimikada, batroolka, iyo warshadaha gaaska dabiiciga ah. Waxay ka helaan calaamadaha nidaamka kontoroolka waxayna si sax ah u hayaan furitaanka waalka, taas oo ay ku xakameynayso qulqulka dareeraha iyo la kulanka baahiyaha habraacyada warshadaha ee kala duwan.
