ʻO API599 plug valve he pahu wili me kahi ʻāpana pani a i ʻole ke ʻano plunger.Ma ka hoʻololi ʻana i nā degere 90, hoʻopili ʻia a hoʻokaʻawale ʻia ke awa kahawai ma ka plug valve a me ke awa kahawai ma ke kino valve e ʻike i ka wehe a pani ʻana paha.
ʻO ke ʻano o kāna plug valve he cylindrical a conical paha.I loko o nā puʻupuʻu cylindrical valve, maʻa mau nā kahawai;i loko o nā pahu valve conical, he trapezoidal nā kahawai.Hoʻomaʻamaʻa kēia mau ʻano i ke ʻano o ka valve plug.ʻOi aku ka maikaʻi ma ke ʻano he ʻoki ʻoki a me ka pilina pili a me ka shunt, akā ma muli o ke ʻano o ka noi a me ke kūpaʻa erosion o ka ʻili hoʻopaʻa, hiki ke hoʻohana ʻia i kekahi manawa no ka throttling.
Wahi a ka hoʻolālā, hiki ke hoʻokaʻawale ʻia i ʻehā mau ʻano: paʻa paʻa paʻa paʻa paʻa paʻa paʻa, paʻa paʻa paʻa paʻa paʻa paʻa, pahu pahu a me ka ʻaila injection plug valve.Wahi a ke ʻano o ke kahawai, hiki ke hoʻokaʻawale ʻia i ʻekolu ala plug valve, ʻekolu ala plug valve a me ʻehā ala plug valve.Aia pū kekahi puʻupuʻu puʻupuʻu kaomi.
