304 simbi isina tsvina duplex simbi yakakwira-kudzvanywa yakaumbwa simbi flange bhora vharafu, PN63 yakakwirira tembiricha uye sulfur kuramba, zvinoenderana nenyika neAmerica zviyero.

Stainless steel duplex steel high-pressure forged steel flange ball valve ivharuvhu yemhando yepamusoro ine tembiricha yakanakisa inodzivirira, kusaririra nesarufa, uye kutevedzera zvinodiwa nenyika neAmerica. Inoshandiswa zvakanyanya mumaindasitiri akadai sekemikari, peturu, uye gasi rechisikigo kudzora kuyerera kwemvura nekumanikidza. Iri vharafu yebhora rakagadzirwa nesimbi isina duplex simbi zvinhu, zvine simba rakawanda, corrosion resistance, uye kupfeka kuramba. Nzvimbo yayo yekuisa chisimbiso yakarapwa yakakosha kuve nechokwadi chekuisa chisimbiso chakanaka uye kudzivirira kuvuza. Zvichakadaro, vheji yebhora inewo zvakanakira chimiro chakareruka, kuisirwa kuri nyore, uye kugadzirisa kuri nyore. Tafura yekuenzanisa saizi yemuenzaniso: |Muenzaniso | zita dhayamita (DN) | kushanda kumanikidza (MPa) | inoshanda tembiricha renji (℃) | nzira yekubatanidza| |-- | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --| |DQ41F | 15-150 | 1.6 | -29-300 | flange| |DQ341F | 25-300 | 2.5 | -29-300 | flange| |DQ61F | 40-400 | 4.0 | -29-300 | flange| |DQ941F | 50-600 | 6.4 | -29-300 | flange| |DQ641F | 80-900 | 10.0 | -29-300 | flange| Iwo ari pamusoro apa modhi zviyero ndezvekutarisa chete, uye iyo chaiyo sarudzo inofanirwa kutariswa zvichienderana nemamiriro chaiwo ekushanda uye zvinodiwa.
