Likahare tsa tlhahlobo ea selemo sena ke: hlahloba hore na ho na le bothata leha e le bofe ka mokhoa oa ho lokisa, ho fetola mocheso ka letsoho, ho bona hore na ho na le boemo bo lumellanang ba valve ea ho lokisa; Hlahloba ho lutla ha capillary.
(2) Ka lebaka la khetho ea sekhomaretsi sa foam ho kenya letsoho mocheso, ho fella ka sekhomaretsi sa foam ka har'a valve, e le hore valve e khomarele. Ka mor'a ho fetola mokhoa oa ho thibela mocheso, bothata bona bo rarolloa ka nako.
(3) The actuator e tsitsitse ka lebaka la ho bola ha carbon steel torsion spring. Bothata bo ile ba rarolloa ka ho fetola seliba sa torsion hore e be tšepe e sa hloekang.
(4) Bakeng sa liphaephe tse sebelisoang hanyenyane, likarolo tse ling lia thijoa hobane li-valve tse itšebetsang ha li sebetse nako e telele. Tlhokomelo ea kamehla le calibration e etsoa bakeng sa valve ho fokotsa monyetla oa ho hlōleha ho tloaelehileng.
