NSEN yakagadzirira 2 seti yevhavha, kusanganisira 150LB uye 600LB mavharuvhu, uye ese ari maviri akapasa bvunzo yemoto.

Naizvozvo, iyo API607 certification yawanikwa parizvino inogona kuvhara zvachose mutsara wechigadzirwa, kubva mukumanikidza 150LB kusvika 900LB uye saizi 4 ″ kusvika 8 ″ uye yakakura.

Kune marudzi maviri echitupa chekuchengetedza moto: API6FA uye API607.Yekutanga inoshandiswa kuAPI 6A mavharuvhu akajairwa, uye yechipiri inonyanya kushandiswa kune 90-degree mavharuvhu anoshanda senge butterfly mavharuvhu uye bhora mavharuvhu.

Zvinoenderana neyakajairwa API607, vheji yakaedzwa inoda kupisa mumurazvo we750 ℃ ​​~ 1000 ℃ kwemaminitsi makumi matatu, uye wozoita 1.5MPA uye 0.2MPA bvunzo kana vharuvhu yatonhodzwa.

Mushure mekupedza bvunzo dziri pamusoro, imwe bvunzo yekushandisa inodiwa.

Valve inogona kupasa bvunzo Chete kana kuyerwa kuvuza kuri mukati meiyo chiyero cheyese pamusoro pebvunzo.
