Iyadoo horumarinta dhaqaalaha caalamiga ah iyo hagaajinta heerka warshadaha, iyo shuruudaha xakamaynta adag ee xuduudaha warshadaha, warshado badan iyo kuwo badan ayaa bilaabay inay raacaan xakamaynta tooska ah.Way isticmaali doonaanactuator koronto balanbaalis, qalabka korontada ku shaqeeya, kontoroolka korantada, korantada diaphragm valve, valve xakamaynta pneumaticiyo wixi la mida.Si kastaba ha noqotee, hirgelinta xakamaynta tooska ah ee saameynta ugu weyn ee xuduudaha ayaa ahfirfircoone.

Waxaa jira laba nooc oo aasaasi ah oo hawlgalka valve si loo tixgeliyo marka la tixgelinayo shuruudaha otomatiga, taas oo ah, doorashada jileeyaha.

Mid waa hawl-wadeenada xagal-stroke, sida kiciyeyaasha korantada ee rubuc-wareegaya, kiciyayaasha pneumatic-ka ee hal-jira, iyo hawl-wadeenada pneumatic-ka oo laba-jibbaaran.Dhaqdhaqaaqayaashani waxay ku wareegaan 90 darajo iyadoo loo eegayo qulqulka loo baahan yahay.Waxaa lagu heli karaa waalka kubbadda, balaalista valve, valve gate, isku darka waalka globe.

Quarter-turning actuator koronto ilaa 4000Nm, waxaana lagu xakameyn karaa gacanta.Waxaa jira 4 nooc oo aad dooran karto, kuwaas oo kala ah nooca beddelka, nooca hagaajinta, nooca caqliga, nooca qarxinta iyo nooca dib u dejinta garaadka, ayaa si weyn loogu isticmaali karaa meelo kala duwan.Sicir la awoodi karo, kharash badan oo waxtar leh, oo aad looga jecel yahay suuqa.

Dhaqdhaqaaqayaasha pneumatic iyo hydraulic waa kuwo aad u badan sababtoo ah uma baahna awood iyo qaab-dhismeed fudud, waxqabad la isku halleyn karo, xawaaraha beddelka waa mid aad u dhakhso badan, isku mid ah ayaa sidoo kale loo isticmaali karaa kubbadda kubbadda iyo balastarka, sidaas darteed beertu waa mid aad u ballaaran.

Midda kale waa waalka-rogadka badan, oo sidoo kale loo yaqaan istaroogga tooska ah.Albaabkani waxa ay noqon karaan jirida wax qaadis ah oo aan wareegeyn ama wareegta jirida aan kor u qaadin, una baahan wareeg dheeraad ah si ay waalka ugu geyso meel furan ama xiran.Dabaqadaha badan ee leexsada waxaa ka mid ah iyada oo loo marayo Valve (globe valve), waalka albaabka, waalka albaabka mindida iyo wixii la mid ah.

Waxaa ka mid ah, dhaqdhaqaaqa-soo-saarka badan ee dareeraha ah ama toosan ee wax soo saarka ayaa inta badan loo isticmaalaa in lagu shaqeeyo iyada oo loo marayo valve (valve globe) iyo albaabka albaabka, sababtoo ah qaab-dhismeedkiisa fudud, waxqabad la isku halleyn karo, way fududahay in la gaaro habka hawlgalka ee badbaadsan.Guud ahaan, qalabka korontada ku shaqeeya ee kala duwan ayaa loo isticmaalaa in lagu kaxeeyo albaabbada iyo globe valves, iyo hawo-qaadayaasha hawada ama pneumatic-ka ayaa la tixgeliyaa kaliya marka korontadu aysan jirin.

Beddel ahaan, pneumatic ama dhululubada haydarooliga ama jilayaasha filimada leh wax soo saarka toosan ayaa sidoo kale wadi kara waalka.
