iivalve zokujonga kabini kunokwenzeka ukulawula inkxaso kunye nokuhamba komthwalo omisiweyo kumacala omabini okusebenza. Ukusetyenziswa okuqhelekileyo kolu hlobo lwevalve kubukho beesilinda ezisebenza kabini ofuna ukuzivalela kwindawo yokusebenza okanye yokuphumla. Isitywina se-hydraulic siqinisekiswa nge-poppet eqiniweyo kunye nephantsi komhlaba. Ndiyabulela kwi-pilot ratio, uxinzelelo lokukhulula lungaphantsi kunolo olubangelwa ngumthwalo omisiweyo.
Iivalve ze-VRDF ziyafumaneka kunye ne-BSPP-GAS i-threaded port kwi-line delivery and return lines and flanged ports on thelines to the cylinder. Ngokuxhomekeke kubukhulu obukhethiweyo, banokusebenza kunye neengcinezelo zokusebenza ukuya kwi-350 bar (5075 PSI) kunye ne-45 lpm (13.2 gpm) izinga lokuhamba. Umzimba wangaphandle wenziwe ngentsimbi ephezulu kwaye ukhuselwe ngaphandle kwi-oxidation kunye nonyango lwe-galvanizing. Unyango lwe-Zinc/Nickel luyafumaneka xa luceliwe kwizicelo ezivezwe ngokukodwa kwiiarhente ezidlekayo.
