DG4V-5-6CJ-MUH6-20球阀 对密封面的角度的精度要求不高，温度变化不易引起楔住现象， 密封面的磨损可以在维修时加垫片补偿。缺点是，这种结构零件较多，同时在粘性介质 中容易粘结，影响密封。尤其是当上下挡板或螺栓螺母强度常年锈蚀后闸板容易脱落失 效。 DG4V-5-6CJ-MUH6-20球阀 VICKERS DG4V-3-6C-M-VI-T-7-52 0805/12V VICKERS V201P8P 1C11 VICKERS DG4V-3-2C-H-L-CDL-60 VICKERS DG3VP-3-102A-VM-UH-10 VICKERS 02-178049，240V VICKERS PVQ20 B2R SSIS 20 CD21D 20 VICKERS PVQ20 B2R SSIS 21 C21D 12 VICKERS 1A07RP01GM VICKERS DG4V-3-2A-MUH-60 VICKERS DG4V-5-2A-MUH-60 VICKERS SG307-F-350 VICKERS H 507848,PQ05/05 VICKERS H 507848,PQ06/05 VICKERS H 507848,PQ07/05 VICKERS H 507848,PQ3/04 VIPA VIPA 221-1BH10 DI16*DC24V VICKERS DG4V-3-2A-M-U-D6-60 VICKERS DG4V-3-6C-M-U-D6-60 VICKERS DG4V-3G-OC-M-U-D5-60 VICKERS DG4V-3-OB-M-U-D6-60 VICKERS 507826(220V) VICKERS 507828(24V) VICKERS 507834(220V) VICKERS VT-VSPA2-50-10/T1 VICKERS EEA-PAM-513-A-32 VICKERS EEA-PAM-523-A-30 VICKERS EEA-PAM-523-A-32 VICKERS CVCS25 03 B29 M35011 VICKERS EPV-16-B-10-S-5C-24D-M-U-13 VICKERS EEA-PAM-520-A-14 VICKERS KDG4V 3 2ALMUH760 VICKERS 02-178049 240V VICKERS 507826(220V) VICKERS 507828(24V) VICKERS 507834(220V) VICKERS DG4V-5-2A-M-U-C6-20 VICKERS DGMC-5-PT-FW-B-30 VICKERS RV3-10-C-0-18 VICKERS 5000PSI DRV-12-01.syg p1/5 VICKERS 879239 DG4S4 0120 U H 60 VICKERS DG4V-3C-2C-M-U6-H5-60 VICKERS DG4V-3S-2A-M-U6-H5-60 VICKERS DG4V-3S-2B-M-U6-H5-60 VICKERS DG4V-3S-2C-M-U-H5-60 VICKERS DG4V-3S-6C-M-U6-H5-60 VICKERS DG4V-3S-8B-VM-U6-H5-61 VICKERS DG4V-3S-8C-VM-U6-H5-61 VICKERS DGMC2-3-AT-GW-BT-GW-41 VICKERS DGMC-3-ABK-BAK-41 VICKERS DGMFN-3-Z-P2W-41 VICKERS DGMR-3-TA-FW-S-40 VICKERS DGMX1-3-PP-BW-B-40-EN12 VICKERS DGNFN-3-Y-A2W-B2W-41 VICKERS KFDG4V 3 86639 12 DGMX1 3 PP VICKERS KFDG4V-3-2C20N-Z-M-U1-H7-20 KDGM VICKERS KFDG4V-3-33C20N-Z-M-U1-H7 VICKERS KFDG4V-3-866340-12 VICKERS KFDG5V-8-33C270N-X-VM-U1-H1-12 VICKERS MR-3-TA-FW-S-40 VICKERS RANGE MIN TO 1000PSI MODLE XCS VICKERS RCT-03-B-2290 0210 VICKERS B507833 VICKERS DG4V 26C MU B660 AC110 VICKERS DG4V 30C MU B660 AC110 VICKERS PVQ20-B2RSE3S-21-C21V11B-130410
