美國VICKERS電磁閥/威格士VICKERS安全閥,VICKERS電磁閥和安全閥為一體,組成先導(dǎo)式壓力閥,該閥即是卸荷閥又是安全閥,有時(shí)又是溢流閥.卸荷時(shí)其控制油道貫穿各路換向閥,同前述卸荷油道.當(dāng)各路換向閥處于中立位置時(shí),卸荷閥的控制油道貫穿各路換向閥并與油箱連通.卸荷時(shí),大部分油液卸荷,通道短,壓力損失低.任一路閥換向工作,便切斷控制油道,油源來油就從換向閥進(jìn)入執(zhí)行元件工作,其工作壓力大小由導(dǎo)閥控制.此時(shí)系統(tǒng)壓力為導(dǎo)閥調(diào)整壓力.該種卸荷方式,即使換向閥路數(shù)增加,只是控制油道增加,卸荷壓力增加不大,始終保持較低卸荷壓力,此種卸荷方式多用于手動換向閥,卸荷可靠.VICKERS電磁閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件(見液壓伺服系統(tǒng))。在伺服系統(tǒng)中,液壓執(zhí)行機(jī)構(gòu)同電氣及氣動執(zhí)行機(jī)構(gòu)相比,具有快速性好、單位重量輸出功率大、傳動平穩(wěn)、抗干擾能力強(qiáng)等特點(diǎn)。另一方面,在伺服系統(tǒng)中傳遞信號和校正特性時(shí)多用電氣元件。因此,現(xiàn)代高性能的伺服系統(tǒng)也都采用電液方式,伺服閥就是這種系統(tǒng)的必需元件。VICKERS旗下產(chǎn)品VICKERS柱塞泵、VICKERS葉片泵、VICKERS電磁閥、VICKERS油泵、VICKERS變量泵、VICKERS液壓馬達(dá)、VICKERS方向閥、VICKERS壓力閥、VICKERS流量閥、VICKERS比例閥、VICKERS定量泵、VICKERS馬達(dá)等。VICKERS系列葉片泵有V系列、V(Q)系列、柱塞泵有:PFB系列、PVB系列、PV/PF系列、TPV系列、PVH系列、PVH系列、PVQ系列等。 美國VICKERS電磁閥/威格士VICKERS安全閥,VICKERS威格士型號:VICKERS線圈508169、507848、507825、507826、507833、507834、617475、617476、02-101728、PVQ45B2R-A9 H02-123993、CKIT584326 02-17808 DGMFN-5-Y-A2W-B2W-10 DGFN-06-50 DGMFN-5-Y-A2W-B2W-30 DGMFN-3-Y-A2W-B2W-41 DGMFN-3-Y-A2W-B2W-30 DGMFN-3-Y-A2W-41-B2W-30(41) DGMFN-3-Y-A2W-B2W-40 DGMFN-3-X-A2W-40 DGMFN-3-Y-A2W-40 C5G-815 DGMDC-5-Y-PM-30 DGMPC-5-BAK-30 DGMPC-5-ABK-30 DGMPC-7-ABK-BAK-10 PCGV-6FD-1-10 4CG-03-A-21 DGMPC-5-ABN-30 DGMPC-5-ABN-BAN-30 DGMPC-3-ABM-BAM-40 DGMPC-3-ABK-BAK-40 DGPC-06-DADB-51 DGMPC-5-ABK-BAK-30 DG17V4-012C-10 KDG4V-3-33C30X-H-M-U-H7-60 VVS1-16-SRRM-30-C-AW-11 DG20V-3-2A-40 DG4V-3S-2N-M-U-H7-60 DG4V-3S-2A-M-U-H5-60 DG4S4-010A-U-H-60-LH DG4S4-016C-U-H-60 DG5S-H8-2C-E-M-U-H5-60 DG4V-3-0AL-M-U-H5-60 DG5S-H8-3C-T-M-U-H5-60 DG5S-H8-6AL-E-M-U-H5-60 PVH074R01AA10A250000001001AE010A SG307-F-350 DT15S2-060-K-11 PVH057R01AB10A250000002001AE010A DG4V-3-2A-VM-U-XA7-60 DG5S-H8-8C-2-S-VMU-A6-41 PVH131R13AF30A250000001001AE010A DG4V-3-8C-VM-U-A6-60 DG5S4-042-T-60-EN546 02-123993 KAHDG5V-8-2C300N-EX-VM-F-PD7-H1-20 DT8P1-06-30-11 DG4V-3-2AL-M-U-SA7-60 DGMR-5-A2-FH-B2-FH-30 PVB15-RS-40-C-11 DS8P1-03-30-10 DG4V-3-24A-M-U-D6-60 DG4V-3-2A-M-U-D6-60 DG4V-3-2C-M-U-D6-60 FCG-02-1500-50 FT257/5-38 DG5V-5-2C-M-U-D6-10 DGMFN-5-X-P2W-30 DGMFN-5-X-B2W-30 KDG4V-3-2C-20N-M-U-H7-60 XCG2V-6BM-10 DGMFN-3-Y-A2W-B2W-40 DGMFN-3-X-A2W-B2W-40 DGMPC-3-ABM-BAM-40 DG4V-3-6C-M-U-H7-60 DG4V-3-2C-M-U-H7-60 DG4V-3-2A-M-U-H7-60 DGMX1-3-PP-BW-B-40 DT8P1-06-5-11 VVP1-20-RRM-30-CBK-10 DG4S4W-012A-D-60 EHST-3FVE-30 DG4V-3-2N-H-M-U-C6-60 300AA00006A 300AA00126A DG4V-3S-6C-M-FW-D5-60 F13-DG4V-5-6CJ-M-U-H6-20 RG-10-Y1-22-UG CG2V-6BW-10 美國VICKERS電磁閥/威格士VICKERS安全閥,VICKERS威格士型號:ST307-V2-350-B FSPA-2418 ST307-V2-350-B 81304113DWG/03 C02-101732 PVH131R13AG30A250000001001AB010A KCG-3-350D-Z-M-U-HL1-10 EEA-PAM-535-A-32 PVQ20-B2R-SE1S-20-C21-11-S2 KBSDG4V-3-92L-40-PE7-H7-10 CG5V-6FW-D-M-U-H5-20 SV15-8-C-0-24DGP SG307F-350 VF1-16-F-6G-30-00 DGMFN-3-X-A2W-40 DGMFN-3-Y-A2W-40 KBSDG4V-3-92L40-PC7-H7-10 V20-1P11P-1C11R CVCS-40-A-B29-W-10 CVCS-25-B-29-10 CVI-40-R16-L-40 CVCS-40-D3-B29-10 20V-11A-1A-22R EEA-PAM-533-A-32 DG4V-3S-6C-M-U-B5-60 VVA40-P-CCWW-21 02-104808 ME750ANS BC300F A02-124515 PVH131R13AF30B252000001001AE010A 26004-RZC PVH74QIC-RSF-1S-10-C25V-31-057 DG3VP-3-102A-VM-U-H-10 DG5S-8-2A-T-M-U-H7-40 PVH131L16AF30A250000001AD100010 45V60A-1B22L 45V60A-1D22R 4CT-06-C-21 DG4V-5-22ALJ-M-U-H6-20 CT-06-C-50 PVH131R16AF30A250000001AD1AB010A PVH131R03AF30A250000001001AB010A DF10P1-16-5-20 PVH131L03AF30A25000000100100010A DG4S4-016C-B-60 CF-16-C-10 DG4V-3S-0B-VM-U-H5-60 PVH131Q1C-RSF-13S-10-C25-31 FG-3-180-K-10 KBDG4V-5-33C-30N-Z-M1-PE7-H7-10 617948 CVCS-25-A-B29-W-10 CVI-25-F-2-M-10 CVCS-16-A-B29-W-10 CVI-16-F-2-M-10 PVB5-RSY-40-CC-12 02-178049 EEA-PAM-523-C-32 PVH074R01AA10A250000002001AB010A PVH131R13AF30A25000000100100010A DG4V-5-2AJ-M-U-P6-20 DG4V-3-2A-M-U-P7-60 KTG4V-3S-2B08N-M-U1-H5-60-EN427 EPRV1-16-5.00-0-24DG PA5DG4S4LW-017C-B-60 DG4S4LW-0
