Kev siv hluav taws xob hluav taws xob feem ntau muab faib ua hluav taws xob ua hluav taws xob ua hluav taws xob thiab siv hluav taws xob ua hluav taws xob, uas feem ntau tuaj yeem ua tiav tag nrho-qhib lossis tag nrho kev tswj ntawm lub valve. Lub valve yog nyob rau hauv txoj hauj lwm qhib lossis qhib tag nrho. Qhov hom qoj no tsis tas yuav tsum tau tswj kev tswj ntawm lub suab nruab nrab.
on-off type electric actuators tuaj yeem muab faib ua hom sib cais thiab hom sib luag vim lawv cov qauv sib txawv. Ntawd yog hais, lawv yog cov hom hloov hom hluav taws xob actuators thiab kev hloov hom hloov hom hluav taws xob actuators. Lawv yuav tsum tau piav qhia thaum xaiv, txwv tsis pub, Thaum lub sijhawm teeb tsa ntawm thaj chaw, feem ntau yuav muaj kev tsis sib haum xeeb nrog cov kev tswj kav thiab lwm qhov tsis sib xws.
