kaviri cheki mavharuvhu zvinokwanisika kubata kutsigirwa uye kufamba kwemutoro wakamiswa mumativi ese ekuita. Iyo yakajairika kushandiswa kwerudzi urwu rwevharuvhu iri pamberi peaviri-anoita masilinda aunoda kukiya munzvimbo yekushanda kana yekuzorora. Iyo hydraulic seal inovimbiswa neakaomeswa uye pasi tapered poppet. Kutenda kune reshiyo yevatyairi, kuburitsa kwakadzikira pane kunokonzerwa nemutoro wakamiswa.

Mavharuvhu eVRDF anowanikwa aine BSPP-GAS yakarukwa madoko pakutakura uye mitsara yekudzoka uye madoko akachinjika pamitsetse kuenda kuhumburumbira. Zvichienderana nehukuru hwakasarudzwa, vanogona kushanda nekumanikidza kwekushanda kusvika ku350 bar (5075 PSI) uye 45 lpm (13.2 gpm) kuyerera kwehuwandu. Muviri wekunze wakagadzirwa nesimbi yakasimba-yakasimba uye yakadzivirirwa kunze kubva kune oxidation ine galvanizing kurapwa. Zinc/Nickel kurapwa kunowanikwa pakukumbirwa kwezvikumbiro zvakanyanya kuratidzwa kune zvinoora.
