Operation principle
- The safety valves enables accurate spool positioning by the movement' on and off of the magnetic field and the position sensing point which built into LVDT(Linear variable differential transformer.
- The output signals from the sensors and entering the industrial computer, by this operator data computing to comtrol ordrive hydraulic components
Feayures
A. The safety valves have 4 sizes:G02,G03,G04,G06 suitable for the use of the different flows of hydraulic components.B. Protection class reaches IP67,stainless steel housing is strong with beautiful.
C. Electronic specificaton
lnput supply voltage | 18~24VCD(±10%) |
---|---|
Recommended output current per channel | ≦50mA |
Max. output current per channel | 400mA |
Max.output drop | ≦6V |
Switch point deviation | ≦0.5mmc |
Ambient temperature | 0~50°C |
Protection class | IP67 |
D.Statement of connector and wiring.
- VCC(18~28V DC)-Red wire
- Output B,White wire。
- GND,Black wire。
- Output A-Blue wire。
- The shield wire connected with the junction box
reached, output A (4pin) non-conductive - normally closed; output B (2pin)
conductive-normally opened. The distance of switching operation is due to the
inner tube from the outer tube on the moving position or spool’s thread to adjust.
Notes:
- When the LVDT(Linear variable differential transformer) is used in the inductive load, such as the inductive load, such as the motor, the relay coil,etc. If the contact point's contacts open(load circuits) will produce high induced voltage and the impact(instantaneous) of the high induced voltage may damege the LVDT(Linear variable differential transformer) or significantly reduce the safety valve life. For this reason, recommend that the client use a surhe protection device.
- Do not re-adjust the safety valve main body. Do not transfer the internal and external components of the safety valve. Do not change or transfer the thorottle body of the safety valve.
- The LVDT(Linear variable differential transformer) of the safety valve can only be set and checked by the manufacturer.
- The hydraulic system must ensure that the spools to avoid shock or vibration.
- Please avoid the safety valve fall to the hard ground from higher than 30cm.
- Please avoid the pollution of the hydraulic oils, otherwise , it will reduce the safety valve life even damage. Filters should use the filration:âX=75im,X = 25im class.
- The hydraulic oils should use the ISO VG45 degree's hydraulic oils and hydraulic fluid.
