不銹鋼閘閥 304材質不銹鋼法蘭閘閥 Z41W-16P DN80的啟閉件是閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關，不適合作調節和節流。閘板有兩個密封面，zui常用的楔式閘板閥的兩個密封面形成楔形，楔形角隨閥門參數而異，通常為5o。楔式閘閥的閘板可以做成一個整體，叫做剛性閘板；也可以做成能產生微量變形的閘板，以改善其工藝性，彌補密封面角度在加工過程中產生的偏差，這種閘板叫做彈性閘板。 閘閥關閉時，密封面可以只依靠介質壓力來密封，即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閥門關閉時，要依靠外力強行將閘板壓向閥座，以保證密封面的密封性。 不銹鋼閘閥 304材質不銹鋼法蘭閘閥 Z41W-16P DN80具有以下優點； 1．流體阻力小，密封面受介質的沖刷和侵蝕小。 2．開閉較省力。 3．介質流向不受限制，不擾流、不降低壓力。 4．形體簡單，結構長度短，制造工藝性好，適用范圍廣。 公稱壓力或壓力級：PN1.0-16.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公稱通徑或口徑：DN10～1000、NPS 1/2 ～36" 連接方式：法蘭、對焊、螺紋等適用溫度：-196℃～700℃ 驅動方式：手動、傘齒輪傳動、氣動、電動、液動、氣液聯動、電液聯動 閥體材料：WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)、Ti。選用不同的材質，可分別適用于水、蒸汽、油品、硝酸、醋酸、氧化性介質、尿素等多種介質。 Z41W-16P DN80:Z41H-10C DN32/Z41H-10C DN40/Z41H-10C DN50/Z41H-10C DN65/ Z41H-10C DN80/Z41H-10C DN100/Z41H-10C DN125/Z41H-10C DN150/Z41H-10C DN200/ Z41H-10C DN250/Z41H-10C DN300/Z41H-10C DN350/Z41H-10C DN400/Z41H-10C DN450/ Z41H-10C DN500/Z41H-10C DN600/Z41H-10C DN700/Z41H-10C DN800/Z41H-10C DN900/ Z41H-10C DN1000/Z41H-16C DN32/Z41H-16C DN40/Z41H-16C DN50/Z41H-16C DN65/ Z41H-16C DN80/Z41H-16C DN100/Z41H-16C DN125/Z41H-16C DN150/Z41H-16C DN200/ Z41H-16C DN250/Z41H-16C DN300/Z41H-16C DN350/Z41H-16C DN400/Z41H-16C DN450/ Z41H-16C DN500/Z41H-16C DN600/Z41H-16C DN700/Z41H-16C DN800/Z41H-16C DN900/ Z941H-16C DN1000/Z41H-25C DN32/Z41H-25C DN40/Z41H-25C DN50/Z41H-25C DN65/ Z41H-25C DN80/Z941H-25C DN100/Z41H-25C DN125/Z41H-25C DN150/Z41H-25C DN200/ Z41H-25C DN250/Z41H-25C DN300/Z41H-25C DN350/Z41H-25C DN400/Z41H-25C DN450/ Z41H-25C DN500/Z41H-25C DN600/Z41H-25C DN700/Z41H-25C DN800/Z41H-25C DN900/ Z41H-25C DN1000/Z41H-40C DN32/Z41H-40C DN40/Z41H-40C DN50/Z41H-40C DN65/ Z41H-40C DN80/Z41H-40C DN100/Z41H-40C DN125/Z41H-40C DN150/Z41H-40C DN200/ Z41H-40C DN250/Z41H-40C DN300/Z41H-40C DN350/Z41H-40C DN400/Z41H-40C DN450/ Z41H-40C DN500/Z41H-40C DN600/Z41H-40C DN700/Z41H-40C DN800/Z41H-40C DN900/ Z41H-40C DN1000/Z41H-64C DN32/Z41H-64C DN40/Z41H-64C DN50/Z41H-64C DN65/ Z41H-64C DN80/Z41H-64C DN100/Z941H-64C DN125/Z41H-64C DN150/Z41H-64C DN200/ Z41H-64C DN250/Z41H-64C DN300/Z41H-64C DN350/Z41H-64C DN400/Z41H-64C DN450/ Z41H-64C DN500/Z41H-64C DN600/Z41H-64C DN700/Z41H-64C DN800/Z41H-64C DN900/ Z41H-64C DN1000/Z41H-100C DN32/Z41H-100C DN40/Z41H-100C DN50/Z41H-100C DN65/ Z41H-100C DN80/Z41H-100C DN100/Z41H-100C DN125/Z41H-100C DN150/Z41H-100C DN200/Z41H-100C DN250/Z41H-100C DN300/Z41H-100C DN350/Z41H-100C DN400/ Z41H-100C DN450/Z941H-100C DN500/Z41H-100C DN600/Z41H-100C DN700/Z41H-100C DN800/Z41H-100C DN900/Z41H-100C DN1000
