Ndiyabulela kwii-valve zokujonga kabini kunokwenzeka ukulawula ukuxhaswa kunye nokuhamba komthwalo omisiweyo kuzo zombini iindlela zokusebenzisa. 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.  iivalvu ziyafumaneka nge-BSPP-GAS enemisonto yamazibuko. Ngokuxhomekeke kubukhulu obukhethiweyo, banokusebenza kunye neengcinezelo zokusebenza ukuya kwi-320 bar (4640 PSI) kunye ne-50 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.
