E 'ngoe ea likarolo tsa bohlokoa tsa valve ea heke ea API 6A FC ke bokhoni ba eona bo botle ba ho tiisa. E na le sesebelisoa sa ho tiisa tšepe ho isa ho tšepe, valve e fana ka ts'ebetso e ntle ea ho lutla ho thibela ho lutla ho sa batleheng kapa tahlehelo ea tiiso. Ts'ebetso ena e bohlokoa ho boloka botsitso ba sistimi le ho netefatsa ts'ebetso e bolokehileng le e sebetsang. Ho feta moo, moralo oa li-valve tse nang le torque e tlase o fokotsa boikitlaetso bo hlokahalang ho sebelisa valve, ho ntlafatsa katleho ka kakaretso.
Li-valve tsa heke tsa API 6A li fana ka boemo bo holimo ba boleng le boleng ho ts'ebeliso ea oli le khase. Li-valve tsa heke li sebelisoa haholo-holo bakeng sa taolo ea phallo ea mokelikeli tsamaisong ea taolo ea seliba sa ho cheka le mefuta e mengata ea mokelikeli oa ho phunya (joaloka, ho bolaea mefuta e mengata, ho bipetsa, mekolokotoane ea seretse le mefuta e mengata ea lipompo tse emeng).
Li-valve tsena li na le tsela e ntle ea phallo le khetho e nepahetseng ea setaele sa trim le lisebelisoa bakeng sa bophelo bo bolelele, ts'ebetso e nepahetseng le ts'ebetso. Sekhahla se le seng sa slab heke se ka nkeloa sebaka 'me se fana ka valve e nang le bokhoni bo feletseng ba ho tiisa ka bobeli ka likhatello tse phahameng le tse tlaase. Li-valve tsa Slab Gate li etselitsoe seliba sa oli le khase ea tlhaho, mefuta e mengata kapa lits'ebetso tse ling tsa bohlokoa tse nang le khatello ea ts'ebetso ho tloha ho 3,000 ho isa ho 10,000 psi. li-valve tsena li fanoa ka lihlopha tsohle tsa mocheso oa API le litekanyetso tsa lihlahisoa tsa lihlahisoa PSL 1 ho isa ho 4.
