U-Shaped Integrated Progressive Distributor
The U-Shaped Integrated Progressive Distributor is a one-piece progressive valve for 4 to 12 lubrication points, in R and M builds, each point fed a fixed 0.3 ml per cycle.
How it works
Each trunk piston set delivers its fixed volume to a point using the hydraulic pressure produced by the progressive action of the set before it, so the points are fed strictly in sequence and every point is proved by the fact that the next one gets fed.
Supply the valve with lubricant at pressure and the sequence runs continuously; stop the supply and every piston set stops where it is, resuming from that same point when pressure returns.
Because the body is integrated rather than assembled from separate blocks, there are no inter-block joints to leak and no cumulative assembly dimension to verify before machining a mounting. R models have no cycling feedback switch; M models carry one, so the controller or PLC can confirm the valve is actually cycling rather than merely being fed.
Specifications
Model matrix by order code
The number in the model code is the outlet count, not the dose. Dose is fixed at 0.3 ml per cycle on every model.
Dimensions
The integrated body carries no cumulative assembly dimension, but we hold no dimensioned drawing for it. Ask us before machining a mounting.
How to read the order code
- Type
- U = U-shaped integrated progressive distributor
- Outlet count
- 4 · 6 · 8 · 10 · 12
- Feedback switch
- R = without · M = with cycling feedback switch
Before you order
- The dose is fixed at 0.3 ml per point. Where points need different doses, use an SD block assembly instead.
- Progressive means sequential: one blocked point stops the whole valve. That is the design intent: fit the safety valve at the pump and watch it.
Warranty
One year against manufacturing defect from date of invoice.
How it pairs
The U-Shaped Integrated Progressive Distributor is commonly specified alongside the ZJ Series High Pressure Piston Grease Pump, the NKGH Type Manual Grease Pump, the PJ Series Motor-Driven Grease Pump, and the AP Type Motor-Driven Grease Pump. That is the same recommendation carried on its own datasheet, not a generic same-category suggestion.
Used on
Industry applications
Main, pitch, blade and yaw bearings and the generator: the high pressure progressive class, where full pump pressure reaches every point in turn.
Rolling mills, forging presses, mining and material handling plant, excavators and cranes: points that are hard to reach and easy to forget.
