ZV-B Dual Line Distributor For Dual-Line Lubrication System
The ZV-B distributor is used in dual-line central lubrication systems and is suitable for oil and grease. It meters and delivers lubricants to the lubrication points independently of back pressure. Features include up to 8 outlets, metering volumes from 0.5 to 3.0 ml/cycle.
Description
Feature
The ZVB dual wire distributor is suitable for 40MPa grease or oil dual line lubrication systems. The distributor can be installed with three options: Metering screw, Adjusting device, and Motion indicator.
1. For ZVB with Metering shrews, the Metered volume cannot be adjusted. Only by selecting different index Metering shrews can the Metered volume be changed.
2. ZVB with Adjusting device, Metered volume can be adjusted from zero to rated range, and can judge whether distributor is working properly by observing the Adjusting device.
3. ZVB with motion indicator can adjust the metered volume within the range of zero to rated range, and can control the metered volume by sending a signal through the monitoring switch. Each distributor can only come with one adjustment device.

Instruction
1. When used in dusty, humid and harsh environment, it should be equipped with protective cover.
2. The parallel installation method is preferred in the dual-wire system. Secondly, the series installation method is adopted, and the two G3/8 plugs at the inlet on one side must be removed. The maximum number of serial connections is not allowed to exceed two, and can be installed in parallel and series if necessary.
3. The ZVB-S, Metered volume with Metering screw can not be adjusted, only the Metering screw with different index can be selected to change the Metering screw.
4. For the ZVB-M with Adjusting device, the adjustment of the Metered volume should rotate the adjusting screw of the limiter when the rod is retracted.
5. For ZVB-L with motion indicator, adjustment of Metered volume should be carried out when indicator lever is retracted.
6. If the number of outlets needs to be odd, remove the screws between the corresponding outlets and block the outlet that is not in use with G1/4 “plugs. The upper and lower outlets are connected, and both the forward and reverse movements of the piston are discharged from this outlet.
7. For ease of disassembly, it is best to bend the pipeline from ZVB to lubrication points at a 90 ° angle or use a sleeve joint.
8. The installation surface of the distributor should be smooth and flat, and the installation bolts should not be tightened too tightly to avoid deformation and affecting normal operation during use.
9. It is recommended to use GB70-85 screws M60 x 50 for installation and fixation of ZVB-S and ZVB-M. A 30mm base plate should be provided between the installation surfaces of ZVB-L, and GB70-85 special screws M6 x 85 should be used for installation and fixation.
