HWV 701-300
Chav Kawm 300 Cast Steel Globe Valve yog tsim los tiv thaiv qhov siab tshaj plaws ntawm 740 psi (pounds ib square inch). Qhov kev ntsuas siab no ua rau nws tsim nyog rau cov ntawv thov siab hauv cov chaw tsim khoom uas yuav tsum muaj kev ua haujlwm zoo thiab txhim khu kev qha valve. Lub valve lub cam khwb cia steel tsim kom muaj zog thiab kav ntev, thaum nws lub ntiaj teb valve tsim tso cai rau kom muaj zog throttling thiab tswj kev ntws. Nrog rau nws qhov siab tshaj plaws ntsuas ntawm 740 psi, lub valve no muaj cov kev daws teeb meem rau kev xav tau ib puag ncig, muab kev thaj yeeb ntawm lub siab rau cov neeg siv xav tau kev tswj xyuas kom meej thiab muaj peev xwm kaw tau.
· Tsim thiab Tsim Kho raws li ANSI B16.34
· Flange qhov ntev raws li ASME B16.5
· Lub ntsej muag rau lub ntsej muag raws li ASME B16.10
· Kev ntsuam xyuas raws li API 598
