是使用最广泛的一种阀门，它之所以广受欢迎，是由于开闭过程中密封面之间摩擦力小，比较耐用，开启高度不大，制造容易，维修方便，不仅适用于中低压，而且适用于高压。 截止阀的闭合原理是，依靠阀杠压力，使阀瓣密封面与阀座密封面紧密贴合，阻止介质流通 阀门对其所在的管路中的介质起着切断和节流的重要作用,截止阀作为一种极其重要的截断类阀门,其密封是通过对阀杆施加扭矩,阀杆在轴向方向上向阀瓣施加压力,使阀瓣密封面与阀座密封面紧密贴合,阻止介质沿密封面之间的缝隙泄漏。 ATOS DLOH-2C/NPT-AO/7-24DC ATOS SP-G8-CKP-80/56 ATOS DLOH-2C/NPT-AO/UL-24DC ATOS SP-G8-CL-25/12 ATOS DLOH-2C/NPT-AO-24DC ATOS SP-G8-CL-32/16 ATOS DLOH-2C/PA-M-AO-24DC ATOS SP-G8-CL-40/18 ATOS DLOH-2C/PA-NPT-AO-24DC ATOS SP-G8-CL ATOS DLOH-2C/WP-U-00 ATOS SP-G8-CL-50/22 ATOS DLOH-2C/WP-UX-110RC ATOS SP-G8-CL-63/28 ATOS DLOH-2C/WP-UX-24DC ATOS SP-G8-C ATOS DLOH-2C/WP-UX-24DC/WG ATOS SP-G8-C ATOS DLOH-2C-U-00 ATOS SP-GP8-C ATOS DLOH-2C-UX-110RC ATOS SP-GP8-CI-40 ATOS DLOH-2C-UX-110RC/PE ATOS SP-GP8-CK-200/90 ATOS DLOH-2C-UX-24DC ATOS SP-GP8-CK-40/28 ATOS DLOH-2C-UX-24DC/WG ATOS SP-GP8-CK-50/36 ATOS DLOH-2C-WO/6 ATOS SP-GP8-CK-80/36 ATOS DLOH-2C-WO/M ATOS SP-GP8-CK-80/45 ATOS DLOH-3A/GK-AO-24DC ATOS SP-GUARN CART M-5 10 ATOS DLOH-3A/NPT/WP-AO/7-24DC ATOS SP-GUARN-ADRL-10 ATOS DLOH-3A/NPT-AO/7-24DC ATOS SP-GUARN-AGAM-10 23 ATOS DLOH-3A/NPT-AO/UL-24DC ATOS SP-GUARN-AGAM-20 ATOS DLOH-3A/NPT-AO-24DC ATOS SP-GUARN-AGIR-10 42 ATOS DLOH-3A/PA-GK-AO-24DC ATOS SP-GUARN-AGIR-10 51 ATOS DLOH-3A/R/-UX-24DC ATOS SP-GUARN-AGIR-10/PE ATOS DLOH-3A/R/WP-UX-00 ATOS SP-GUARN-AGIS-10 10 ATOS DLOH-3A/WP/NPT-AO/UL-24DC ATOS SP-GUARN-AGMZO-A-10 ATOS DLOH-3A/WP-NPT-AO-24DC ATOS SP-GUARN-AGRL*-10 ATOS DLOH-3A/WP-U-00 ATOS SP-GUARN-AGRLE-10 41 ATOS DLOH-3A/WP-UX-110RC ATOS SP-GUARN-AGRLE-20 32 ATOS DLOH-3A/WP-UX-230RC ATOS SP-GUARN-AQFR-10 30 ATOS DLOH-3A/WP-UX-24DC ATOS SP-GUARN-CART-ARE-15 ATOS DLOH-3A-U-00 ATOS SP-GUARN-CART-M-3/20/PE ATOS DLOH-3A-UX-110RC ATOS SP-GUARN-D03 COIL ORINGS ATOS DLOH-3A-UX-110RC/PE ATOS SP-GUARN-D05 COIL ORINGS ATOS DLOH-3A-UX-24DC ATOS SP-GUARN-DH-01 50 ATOS DLOH-3A-UX-48DC ATOS SP-GUARN-DH-02 40 ATOS DLOH-3A-WO/H/PE ATOS SP-GUARN-DH-05 72 ATOS DLOH-3C/NPT-AO-24DC ATOS SP-GUARN-DHA 21 ATOS DLOH-3C/R-UX-24DCE ATOS SP-GUARN-DHI 23 ATOS DLOH-3C/R-WO-12/PE ATOS SP-GUARN-DHI/PE 23 ATOS DLOH-3C/S-UX-110RC ATOS SP-GUARN-DHO ATOS DLOH-3C/WP-U-00 ATOS SP-GUARN-DHO 20 ATOS DLOH-3C/WP-UX 48DC ATOS SP-GUARN-DHQ 11 ATOS DLOH-3C/WP-UX-110DC ATOS SP-GUARN-DHZA/PE ATOS DLOH-3C/WP-UX-110RC ATOS SP-GUARN-DHZO ATOS DLOH-3C/WP-UX-24DC ATOS SP-GUARN-DHZO/EP ATOS DLOH-3C-U-00 ATOS SP-GUARN-DK-11 50 ATOS DLOH-3C-UX-110DC ATOS SP-GUARN-DK-12 ATOS DLOH-3C-UX-110RC ATOS SP-GUARN-DK-19 22 ATOS DLOH-3C-UX-24DC ATOS SP-GUARN-DKE ATOS DLOHXS6-3C/PA-M-AO-24DC ATOS SP-GUARN-DKER ATOS DLOK-3A/NPT-AO/UL-24DC ATOS SP-GUARN-DKI 24 ATOS DLOK-3A-OX-24DC ATOS SP-GUARN-DKI/PE ATOS DLOK-3C-OX-110DC ATOS SP-GUARN-DKI/WG ATOS DLOK-3C-OX-220DC ATOS SP-GUARN-DKU 24 ATOS DLOK-3C-OX-24DC ATOS SP-GUARN-DKZOR ATOS DLOPX-6/3A/M/AO ATOS SP-GUARN-DLHZO/EP
