Standard AISI304 kana 316 Stainless simbi gedhi rinokuyiwa uye kukwenenzverwa zvakanaka segirazi, iro rinogona kudzivirira kukuvara kwekurongedza uye chigaro kuburikidza nekuvhura kana kuvhara uye kugadzira chisimbiso chikuru.Pazasi pemupendero wegedhi inogadzirwa kune bevel, zvekuti inocheka nepakati pezvakaoma kuti isimbise chisimbiso munzvimbo yakavharwa.Mudziviriri webanga anogona kupihwa yekuwedzera dziviriro kubva kuguruva.
Pane zvinhu zvitatu zviri pasi apa:
1. Chigaro chekugara NBR, EPDM, inowanikwawo muPTFE, Viton, Silicone etc. Yakasiyana-siyana yakagadzirwa iyo mechanically inovhara chisimbiso mukati memuviri wevharuvhu nesimbi isina tsvina inochengetedza mhete.Kazhinji ndeye unidirectional chisimbiso dhizaini, uye bidirectional chisimbiso sezvakakumbirwa.
2. Matunhu akati wandei eakarukwa kurongedza ane nyore kuwana kurongedza gland kuita kuti chisimbiso chakasimba.Inowanikwa mumhando yezvigadzirwa: Graphite, PTFE, PTFE+KEVLAR nezvimwe.
3. Chivharo chegwaro pamutumbi wevhavha chinoita kuti gedhi rifambe zvakanaka, uye iyo extrusion block inova nechokwadi chekuisa chisimbiso chegedhi.
ZFA Valve inonyatso shandisa API598 yakajairwa, tinoita ese ari maviri ekumanikidza bvunzo kune ese vharafu 100%, inovimbisa kuendesa 100% mhando mavharuvhu kune vatengi vedu.
Muviri wevharuvhu unotora GB yakajairwa zvinhu, kune yakazara gumi neshanu maitiro kubva kusimbi kuenda kune valve muviri.
Kuongororwa kwemhando kubva pane isina chinhu kusvika kune yapera chigadzirwa ndeye 100% inovimbiswa.
