I-NSEN ilungiselele iiseti ze-2 zeevalve, ezibandakanya i-150LB kunye ne-600LB valves, kwaye zombini ziphumelele uvavanyo lomlilo.

Ngoko ke, isatifikethi se-API607 esifunyenwe ngoku sinokugubungela ngokupheleleyo umgca wemveliso, ukusuka kuxinzelelo lwe-150LB ukuya kwi-900LB kunye nobukhulu be-4 "ukuya kwi-8" kunye nobukhulu.

Kukho iindidi ezimbini zesatifikethi sokhuseleko lomlilo: i-API6FA kunye ne-API607.Eyokuqala isetyenziselwa i-API 6A i-valve eqhelekileyo, kwaye eyesibini isetyenziselwa ngokukodwa i-90-degree valves yokusebenza efana ne-butterfly valves kunye ne-valve yebhola.

Ngokomgangatho we-API607, i-valve evavanyiweyo idinga ukutshisa kwilangatye le-750 ℃ ​​~ 1000℃ imizuzu engama-30, kwaye emva koko yenza iimvavanyo ze-1.5MPA kunye ne-0.2MPA xa i-valve ipholile.

Emva kokugqiba ezi mvavanyo zingentla, olunye uvavanyo lokusebenza luyafuneka.

I-valve ingaluphumelela uvavanyo Kuphela xa ukuvuza okulinganisiweyo kungaphakathi komgangatho oqhelekileyo walo lonke uvavanyo olungentla.
