·Osayizi bobuso nobuso bavumelana ne-EN558-1, uchungechunge oluyisisekelo 48(DIN 3202 F6) ukuvala uphawu okuthambile kuvumelana ne-EN 12334
·I-diaphragm iyavalwa, iyashesha futhi ayizwakali
·I-diaphragm material NBR EPDM
Ukuhlolwa kokugcina kuvumelana ne-EN12266
·Usayizi osebenzayo: DN40~DN500
·Izinga lokushisa elisebenzayo: -20~100°C
Umzimba wevalvu: insimbi eyinsimbi/i-nodular cast iron
·Valve disc: EPDM isongwe
1. I-Swing check valve disc 90°C isenzo sinikeza umsebenzi ongcono ongabuyisi oketshezini oluhlanzekile.
2. Insimbi engagqwali noma izinto zangaphakathi zethusi, ukumelana nokuhuzuka okuphezulu, ukusebenza kahle kokuvala kanye nokumelana nokugqwala okuqinile
3. Ivalvu yokuhlola idiski yerabha ivaliwe ngo-45°C, iyashesha futhi ayizwakali, inikeza umsebenzi ongcono lapho ubuya khona oketshezini olunezinto eziningi zangaphandle.
4. I-valve yokuhlola i-rubber disc swing igoqwe yi-EPDM noma ezinye izinto ezifanele ama-mediums ahlukene.
5. Ingaphezulu nangaphakathi lomzimba we-valve kune-epoxy resin-proof-proof coating
