Modular Progressive Divider Valve Block for Grease Systems

The Modular Progressive Divider Valve Block is the mechanical brain of a progressive lubrication system. It receives a single stream of high-pressure lubricant and divides it sequentially among multiple outlets. Inside the block, a series of interlocking pistons are forced to move one after the other. Piston A must complete its stroke before Piston B can move. This mechanical sequencing guarantees that every connected point receives lubricant; if any single line is blocked, the entire block stops, instantly alerting the operator to a problem.

Key Advantages & Benefits:

  • Fault-Proof Lubrication: The sequential design makes it physically impossible to skip a lubrication point without stopping the system.
  • Modular Flexibility: The block is constructed from individual sections that can be added, removed, or swapped to change output volumes.
  • High-Pressure Handling: Specifically engineered to handle thick greases (up to NLGI 2) under extreme pump pressure.
  • Simplified Monitoring: Attaching a single proximity sensor to one piston allows you to monitor the successful operation of the entire block.

Versatile Applications:

  • Wind turbine pitch and yaw bearings
  • Construction excavators and loaders
  • Agricultural combine harvesters
  • Heavy transport truck chassis

Frequently Asked Questions (FAQ):

  • Q: What happens if a bearing line gets crushed or blocked? A: The back-pressure will prevent that specific piston from moving. Because the pistons are interlocked, the entire block will halt, triggering a high-pressure alarm at the main pump.
  • Q: Can I block off an outlet if I have an odd number of lubrication points? A: You cannot simply plug an outlet on a standard progressive block, as it will lock up the system. You must use specific "cross-porting" fittings to combine the flow of two outlets into one.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
