A105 forged steel pob valve yog ua los ntawmASTM A105 forged carbon hlaurau lub cev valve. Lub cev dhau mustuag forging, kho cua sov, thiab CNC precision machining, ua rau aCov qauv ntom ntom tsis muaj porosity lossis blowholes. Nws tuaj yeem tiv taus kev ntxhov siab los ntawmChav Kawm 150 txog 2500Lb (PN16 txog PN420)thiab yog haum raudej, roj, ncu, nkev, thiab tsis muaj zog corrosive medianyob rau hauv qhov kub thiab txias-29℃rau 425 degree. Lub valve ua raws liAPI 6D, ASME B16.34, thiab NACE MR0175cov qauv. Nws muaj nrogflanged, taub qab-welded, qhov (socket)-welded, los yog threadedxaus, nyob rau hauv qhov ntau thiab tsawg los ntawmDN15 rau DN200, thiab tuaj yeem nruab nrogphau ntawv, pneumatic, lossis hluav taws xob actuators. Nws yog dav siv rausiab -siab kaw-offnyob rau hauv ntev - cov kav dej nyob deb, kev faib roj hauv nroog, thiab cov nroj tsuag tshuaj.
