Product Overview
Lub Rising Stem Wedge Gate Valve muab cov kua dej kiag li kaw -tawm thiab saib xyuas qhov pom kev ncaj qha rau kev sib cais cov kav dej tseem ceeb. Ua haujlwm ntawm Sab Nrauv Ntsia Hlau thiab Yoke (OS & Y), qia sawv sab nraud lub cev lub cev thaum lub rooj vag nqa, tso cai rau cov tswv lag luam los txheeb xyuas kab xwm txheej ntawm ib nrais muag.
Thaum qhib tag nrho, lub wedge retracts tag nrho tawm ntawm cov kwj deg. Qhov no tsim kom muaj kev sib tw, tag nrho - bore passage uas txo qis kev poob siab, tiv thaiv kev yaig, thiab tshem tawm cov kua dej. Precision- raug tsim los rau API 600 thiab ASME B16.34 tus qauv, lub valve no muab lub sijhawm ntev - sealing kev ua tau zoo hauv kev xav tau chav, roj, roj, thiab cov kav dej tshuaj lom neeg.
Cov yam ntxwv tseem ceeb ntawm Rising Stem Wedge Gate Valve
Visual Position Verification:Sab nraud qia nce nrog kev ua haujlwm, muab kev lees paub tam sim ntawm qhov xwm txheej valve.
Full -Bore Flow Efficiency:Unobstructed internal geometry txo lub taub hau poob thiab tso cai rau pigging hauv cov txheej txheem kab.
Bi-Directional Sealing:Symmetrical wedge tsim muab kev ruaj ntseg kaw-tawm tsis hais txog kev khiav.
Tsawg-Torque ua haujlwm:Precision- txiav trapezoidal qia threads ua kom lub log du los yog iav actuation.
Customizable Trim Options:Cov khoom sib xyaw ua ke sib phim cov kab siab, xov xwm corrosivity, thiab kev ua haujlwm kub.
