Li-Valve tsa API6A tsa CEPAI li ka aroloa ka mefuta e meraro, e leng li-valve tsa ho hlahloba, Piston Check Valve le Lift Check Valve, li-valve tsena kaofela li entsoe ho latela standard standard ea API 6A 21. Li phalla ka nqa e le 'ngoe' me likhokahano tsa ho qetela li tsamaisoa le API Spec 6A, tiiso ea tšepe le tšepe e etsa ts'ebetso e tsitsitseng ea khatello e phahameng, maemo a mocheso o phahameng. Li sebelisetsoa mefuta e mengata ea Chock le lifate tsa Keresemese, CEPAI e ka fana ka boholo ba bore ho tloha ho 2-1 / 16 ho isa ho 7-1 / 16 inch, le khatello ho tloha 2000 ho isa 15000psi.
