Iivalvu zemoto zifakwe ngaphakathi kwimitha yegesi. Ngokuqhelekileyo, kukho iintlobo ezintathu zemitha yegesi yendlu: 1. ivalve yokuvala ukuvala ngokukhawuleza; 2. ivelufa eqhelekileyo yokuvala igesi; 3. ivalve yebhola yemoto. Ukongeza, ukuba imitha yegesi yoshishino idinga ukulungiswa, ivalve yemitha yegesi yeshishini iyafuneka.

Nazi iimpawu zabo kunye nomahluko:

Ivalve yokuvala ukuvala ngokukhawuleza inokuvalwa ngoko nangoko, ngoko ithiywe ngesantya esikhawulezayo xa ivala. Le valve yokuvala igesi inesixhobo sokuqhuba i-gear-and-rack kwaye ihambelana nemitha yegesi ye-G1.6-G4. Ngaphezu koko, inokongezwa kunye ne-1 (okanye i-2) yokutshintsha kokuphela (ukudlula izibonakaliso ezivulekileyo / ezivaliweyo kwindawo).

Ivalve yokuvala eqhelekileyo incinci xa kuthelekiswa nevalve yokuvala ukuvala ngokukhawuleza, ngoko ayinakongezwa kunye nokutshintsha kokuphela. Le valve Yivalve yokuqhuba i-screw-off, kwaye iyasebenza nakwimitha yegesi ye-G1.6-G4.

Ivalve yebhola yemitha yegesi ingasetyenziswa ngesantya esiphezulu sokuhamba. Yivalve yebhola yokuqhuba kwaye iyakwazi ukuziqhelanisa noluhlu lokuhamba kwemitha yegesi ebanzi, ukusuka kwi-G1.6 ukuya kwi-G6. Ingongezwa kunye ne-1 okanye i-2 ekupheleni kokutshintsha kwakhona. Ngaphezu koko, ukwakheka kwayo kwenza ukuba iphumelele uvavanyo lothuli.

Ivalve yokuvala kwimizi-mveliso ingasetyenziswa kwiimitha zegesi ezinesantya esiphezulu kakhulu sokuhamba. I-valve ye-industrial motor ine-screw drive structure, kwaye iyasebenza kwi-G6-G25 yeemitha zegesi. Olu hlobo lwevalve lunokongezwa kunye nokutshintsha kwe-1 okanye i-2 ekupheleni.

Zonke ezi zivalo zemitha yegesi zingasetyenziswa kwirhasi yendalo kunye neLPG ngokunjalo. Ezinye zezi valve zemoto zingenziwa kwiivalve zangaphandle, ngoko ke uluhlu lwesicelo lwayo lubanzi ngokwaneleyo, lwanele ukusetyenziswa kwegesi yemihla ngemihla.
