Uchungechunge lwe-SL luhlobo olutsha lwezixhobo zonyango lomthombo womoya we-pneumatic, kubandakanywa isihlungi somthombo womoya, i-Pressure regulator kunye ne-lubricator.
Isihluzo somthombo womoya sisetyenziselwa ukucoca ukungcola kunye namasuntswana emoyeni, ukuqinisekisa umgangatho olungileyo womoya ongena kwinkqubo. Isebenzisa izixhobo zokucoca eziphezulu, ezinokususa ngokufanelekileyo uthuli, umswakama kunye negrisi emoyeni, ukukhusela ukusebenza okuqhelekileyo kwezixhobo ezilandelayo.
I-Pressure regulator isetyenziselwa ukulawula uxinzelelo lomoya olungena kwinkqubo yokuqinisekisa ukusebenza okuzinzile kwenkqubo. Inoluhlu oluchanekileyo lolawulo lwe-voltage kunye nokuchaneka, olunokulungelelaniswa ngokweemfuno, kwaye lunesantya esihle sokuphendula kunye nokuzinza.
I-lubricator isetyenziselwa ukubonelela ngeoyile yokuthambisa kwisixhobo somoya kwisistim, ukunciphisa ukungqubana nokunxiba, kunye nokwandisa ubomi benkonzo yezixhobo. Yamkela izinto ezisebenzayo zokuthambisa kunye noyilo, ezinokubonelela ngefuthe elizinzileyo lokuthambisa kwaye linesakhiwo ekulula ukusigcina nokubuyisela.
