ama-valve okuhlola kabili kungenzeka ukuphatha ukwesekwa nokunyakaza komthwalo omisiwe kuzo zombili izinkomba zokusebenzisa. Ukusetshenziswa okujwayelekile kwalolu hlobo lwe-valve kuphambi kwamasilinda asebenza kabili ofuna ukuwakhiya endaweni yokusebenza noma yokuphumula. I-hydraulic seal iqinisekiswa nge-poppet eqinile futhi ephansi. Ngenxa yesilinganiso somshayeli, ingcindezi yokukhululwa iphansi kunaleyo ebangelwa umthwalo omisiwe.

Amavalvu e-VRDF ayatholakala ngezimbobo ezinentambo ye-BSPP-GAS emigqeni yokulethwa nebuyayo kanye nezimbobo ezivulekile emigqeni eya kusilinda. Ngokuya ngosayizi okhethiwe, bangasebenza nezingcindezi zokusebenza ezifika kubha engu-350 (5075 PSI) kanye nesilinganiso sokugeleza esingu-45 lpm (13.2 gpm). Umzimba wangaphandle wenziwe ngensimbi enamandla amakhulu futhi uvikelwe ngaphandle ekufakweni kwe-oxidation ngokwelashwa kwe-galvanizing. Ukwelashwa nge-Zinc/Nickel kuyatholakala uma kuceliwe izicelo ezichayeke ikakhulukazi kuma-ejenti ezonakalisayo.
