Ma API6A Check Valves a CEPAI atha kugawidwa m'magulu atatu, omwe ndi Swing check valve, Piston Check Valve ndi Lift Check Valve, ma valve onsewa adapangidwa malinga ndi API 6A 21th standard standard. Amayenda mbali imodzi ndipo kulumikizana kumapeto kumatsatiridwa ndi API Spec 6A, chisindikizo chachitsulo ndichitsulo chimapanga magwiridwe antchito a kuthamanga kwakukulu, kutentha kwambiri. Amagwiritsidwa ntchito pamitundumitundu ya Chock ndi mitengo ya Khrisimasi, CEPAI imatha kupereka kukula kwake kuchokera pa 2-1 / 16 mpaka 7-1 / 16 inchi, komanso kuthamanga kuyambira 2000 mpaka 15000psi.

Design Mfundo:
Ma Valves a ma Check standard ali molingana ndi API 6A 21th Edition yaposachedwa, ndipo gwiritsani ntchito zida zoyenera pa ntchito ya H2S malinga ndi muyezo wa NACE MR0175.
Mulingo Wazinthu Zazogulitsa: PSL1 ~ 4 Class Class: AA ~ FF Performance Requirement: PR1-PR2 Temperature Class: LU

Zida Zamagulu:
Seal Chisindikizo chodalirika, komanso kukanikiza kwambiri kusindikiza bwino
Noise Phokoso laling'ono logwedera
◆ Malo osindikizira pakati pa chipata ndi thupi ndi ophatikizika ndi aloyi olimba, omwe ali ndi magwiridwe antchito abwino kukana
◆ Kapangidwe ka valavu kakhoza kukhala mtundu wa Kwezani, Swing kapena Piston.
