Ka kakaretso, li-valve tsa ho hlahloba tse otlolohileng li sebelisoa liphaepheng tse tšekaletseng tse nang le bophara ba 50mm. Ho ka kenngoa valve ea ho hlahloba ka ho toba ka har'a liphaephe tse tšekaletseng le tse otlolohileng. Belofo e ka tlase hangata e kenngoa feela phaepheng e emeng ea pompo, 'me e bohareng e phalla ho tloha tlase ho ea holimo.
Swing check valve e ka etsoa khatello e phahameng haholo ea ho sebetsa, PN e ka fihla 42MPa, 'me DN e ka boela ea etsoa e kholo haholo, boholo bo ka fihla ho feta 2000mm. Ho ea ka lisebelisoa tse fapaneng tsa khetla le tiiso, e ka sebelisoa ho leha e le efe ea ho sebetsa le mocheso ofe kapa ofe o sebetsang. Mocheso ke metsi, mouoane, khase, sebaka se senyang, oli, lijo, meriana, joalo-joalo Mocheso o sebetsang oa seaplane o pakeng tsa -196~800℃.
Sebaka sa ho kenya valve ea ho hlahloba swing ha se na moeli, hangata se kenngoa phapeng e otlolohileng, empa e ka boela ea kenngoa phapeng e otlolohileng kapa phaephe e sekametseng.
Ketsahalo e sebetsang ea valve ea ho hlahloba serurubele ke khatello e tlaase le bophara bo boholo, 'me ketsahalo ea ho kenya e lekanyelitsoe.

Sebaka sa ho kenya valve ea ho hlahloba serurubele ha se na moeli, se ka kenngoa ka pipeline e otlolohileng, pipeline e otlolohileng kapa phaephe e sekametseng.
Diaphragm check valve e loketse liphaephe tse tloaetseng hamore ea metsi. Diaphragm e ka felisa hantle hamore ea metsi e bakoang ke ho phalla ka morao ha seaplane. Kaha mocheso o sebetsang le khatello ea ts'ebetso ea li-valve tsa ho hlahloba li-diaphragm li fokotsoe ke lisebelisoa tsa diaphragm, hangata li sebelisoa liphaepheng tse nang le khatello e tlaase le mocheso o tloaelehileng, haholo-holo bakeng sa liphaephe tsa metsi a pompo. Ka kakaretso, mocheso o sebetsang oa bohareng o pakeng tsa -20 ~ 120 ℃, 'me khatello ea ho sebetsa e ka tlaase ho 1.6MPa, empa valve ea ho hlahloba diaphragm e ka finyella bophara bo boholo,' me boholo ba DN bo ka ba ho feta 2000mm.
Diaphragm check valve e 'nile ea sebelisoa haholo lilemong tsa morao tjena ka lebaka la ts'ebetso ea eona e ntle ea ho thibela metsi, sebopeho se batlang se le bonolo le litšenyehelo tse tlaase tsa tlhahiso.
Sesepa sa ho hlahloba bolo se na le ts'ebetso e ntle ea ho tiisa, ts'ebetso e ka tšeptjoang le ho hanyetsa hamore e ntle ea metsi hobane tiiso ke sebaka se koahetsoeng ka rabara; le hobane tiiso e ka ba bolo e le 'ngoe kapa libolo tse ngata, e ka etsoa bophara bo boholo.
