Freya low-temperature type hluav taws xob valve actuator yog tsim rau kev tswj cov li qub siv nyob rau hauv qhov chaw tsis tshua muaj kub. Raws li nws cov hom zoo tib yam, cov khoom siv ntawm lub thawv loj thiab lwm yam kev ntxhov siab-kev coj tus kheej, xws li cov khoom siv hluav taws xob tswj thiab cov xaim, cov khoom sib khi thiab roj. Cov kev ntsuas tau raug coj mus rau qhov kev ua tau zoo thiab kev xaiv lub zog ntawm lub cev muaj zog kom ua tiav qhov kev ua tau zoo ntawm qhov kub thiab txias uas cov khoom yuav tsum muaj. Qhov kub tsis tshua muaj hom I kub yog -25 degrees Celsius mus rau -40 degrees Celsius, thiab qhov kub tsis tshua muaj hom II kub yog -40 degrees Celsius mus rau -55 degrees Celsius. Nyob rau hauv ib puag ncig uas tsis tshua muaj kub, nws ua haujlwm ib txwm thiab ua tau zoo.
