JINPINLUB — Fri, 13 Sep 2024 16:12:37 +0000

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.

Specification

Model	ZV-B
Operating pressure	40 MPa
Action pressure	≤1.0 MPa
Piston output	0.3mL
Discharge	0.5, 1.5, 3.0mL/cycle
Number of outlets	2~8
Lubricant	Grease NLGI 0~3# or Oil ＞ N68
Operating temperature	(-20 ℃ ~ 80 ℃)

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.

Galvanized Steel VSL Metering Devices For Dual-Line System

JINPINLUB — Fri, 13 Sep 2024 15:58:47 +0000

Feature

There are outlets on both the top and bottom of the VSL-KR, and when the distributor piston moves forward and backward, grease is discharged from the outlets on both sides. There is a combined discharge structure in the corresponding upper and lower outlets. To change the odd number of outlets, simply unscrew the screws in the holes. The operation of the distributor can also be directly observed from the action of the indicator rod, and the discharge of each outlet can be adjusted by adjusting the screws. This type of distributor is used under the alternating supply pressure of two main supply pipes, and the piston action is directly controlled by the supply pressure.

Specification

Model	VSL-KR
Operating pressure	40 MPa
Action pressure	≤1.0 MPa
Rated discharge	0~5 mL/cyc
Adjusting screw flow	0.15mL/circle
Number of outlets	2~8
Lubricant	Grease NLGI 0~2# or Oil ＞ N68
Operating temperature	(-10 ℃ ~ 80 ℃)

Instruction

If it is necessary to merge the corresponding upper and lower outlets, simply unscrew the pressure plug in the upper oil outlet hole with a 6mm hex wrench, remove the oil distribution sleeve through hole and install it downwards, then tighten the pressure plug, the upper outlet is blocked with a G14 plug to prevent dust. Distributors used outside the range of -10 ℃ to 80 ℃ must be specified in the purchase in order to provide low and high temperature resistant oil seals during supply.

VSKV-KR Metering Valves For Dual Line Lubrication Systems

JINPINLUB — Fri, 13 Sep 2024 15:48:18 +0000

Feature

The front of VSKV-KR dual line distributor is equipped with upper and lower discharge ports. When the distributor piston moves in both directions, grease is discharged from the upper and lower ports respectively. The working condition of the distributor can also be directly observed from the action of the indicator rod, outlet flow rate can be adjusted within the specified range by adjusting the screw.
VSKV-KR is suitable for a 40 MPa dual line grease centralized lubrication system. Under the alternating pressure of two main lines, it controls the piston to move and discharge, and distributes lubricant quantitatively to lubrication points.

Specification

Model	VSKV-KR
Operating pressure	40 MPa
Action pressure	≤1.5 MPa
Rated discharge	0 ~ 1.5 mL/cyc
Adjusting screw flow	0.05mL/circle
Number of outlets	2~8
Lubricant	Grease NLGI 0~2# or Oil ＞ N68
Operating temperature	(-10 ℃ ~ 80 ℃)

Application

Cement Plant: During cement production, the lubrication of the VSKV-KR distributor ensures smooth operation of the machine and reduces wear.
Mining Excavator: Mining equipment usually works in harsh environments, and the lubrication system of the VSKV-KR metering valve can extend the service life of the equipment.
Steel Plant: Steel production equipment needs to operate under high temperature and high pressure, and the VSKV-KR divider can provide precise lubrication to ensure efficient operation of the equipment.

DV-H ZVC Metering Valves For Dual Line Lubrication Systems

JINPINLUB — Fri, 13 Sep 2024 12:22:46 +0000

Feature

Suitable for 20MPa dual line centralized lubrication systems. It drives the piston to output lubricant under the alternating oil supply pressure of two oil supply pipes, completing the quantitative distribution of lubricant.
DV-H outlets are all at the bottom, and the distributor piston moves forward and backward from the same outlet for output. Every time the system works, each outlet is outputed once.
Operation of DV-H can be directly observed from indicator, and the output volume of each outlet can be adjusted within the specified range by adjusting the screws.
