Umshini wokulinganisa we-valve yensimbi engagqwali kanye nomshini wokupakisha, yonke ingxenye yempahla yokuxhumana yomshini yenziwe ngepuleti lensimbi engagqwali, ilungele ividiyo, imboni yamakhemikhali nezinye izinto ezikhethekile zesikhwama sesikhwama se-valve esinesisindo nomshini wokupakisha.

Umshini wokukala ne-valve wokupakisha uthola isignali yesisindo se-analog ngethuluzi kanye nenzwa bese uyicubungula ibe isignali yedijithali, futhi iguqule isignali nge-relay ukuze ilawule isixhumi esithintayo kanye ne-solenoid valve ukuze ibone ukuphenduka nokuma kwenjini kanye nokusebenza kwesilinda. Umgomo wokukhipha ukusebenzisa ukujikeleza kwesivinini esiphezulu se-impeller yekhanda lamandla ukuze ususe ngokushesha izinto ezivela ku-port yokukhipha, futhi umoya wangaphakathi ushaywa ukuze wenze ukucindezela okukhulu ngaphakathi kwekhanda lamandla futhi impahla ishaywa ukusiza ukukhishwa kwe-impeller.
