I-NSEN ilungiselele amasethi ama-2 wamavalvu, okuhlanganisa ama-valve angu-150LB nama-600LB, futhi womabili aphumelele ukuhlolwa komlilo.

Ngakho-ke, isitifiketi se-API607 esitholakala njengamanje singavala ngokuphelele umugqa womkhiqizo, kusukela kungcindezi engu-150LB ukuya ku-900LB kanye nosayizi 4″ ukuya ku-8″ nangaphezulu.

Kunezinhlobo ezimbili zesitifiketi sokuphepha komlilo: i-API6FA ne-API607.Eyokuqala isetshenziselwa amavalvu ajwayelekile e-API 6A, kanti eyesibili isetshenziselwa ngokukhethekile ama-valve okusebenza angama-90-degree afana namavalvu ovemvane namavalvu ebhola.

Ngokwezinga le-API607, i-valve ehloliwe idinga ukushisa elangabini elingu-750℃~1000℃ imizuzu engu-30, bese yenza izivivinyo ze-1.5MPA kanye ne-0.2MPA lapho i-valve ipholile.

Ngemva kokuphothula lezi zivivinyo ezingenhla, kudingeka olunye uhlolo lokusebenza.

Ivalvu ingaphumelela ukuhlolwa Kuphela uma ukuvuza okukaliwe kungaphakathi kwendawo evamile yakho konke ukuhlolwa okungenhla.
