Product details
 1.Product Overview
TheUD 1.5/4 TV Flow Divideris a precision hydraulic component in theUD Series, designed to split a single hydraulic supply into proportional flows for multiple actuators (e.g., cylinders, motors). Featuring agear-type splitting mechanism, it ensures high-accuracy flow division, low pressure drop, and a compact design, making it ideal for synchronized motion control in construction, agricultural, and industrial machinery.

 Code Meaning Description
UD Series ID UD Series Flow Divider
1.5 Nominal Flow Max. input flow 1.5 L/min (or 1.5 in³/rev; confirm unit)
4 Output Ports 4-way proportional flow division
TV Structure Type T = Gear Type; V = Pressure-Compensated
 
Note: If "1.5" refers to displacement (in³/rev), flow calculations must align with actual design.

4. Structural Features
 
  1. Gear-Type Splitting Core
 
      • High-precision gear pairs ensure proportional flow division across outputs.
 
      • Ideal for synchronized motion (e.g., multi-cylinder lifting, platform leveling).
 
  2. Pressure-Compensated (TV Model)
 
      • Built-in compensator valve balances flow fluctuations caused by load variations, maintaining division accuracy.
 
  3. Compact & Lightweight Design
 
      • Aluminum housing with integrated oil passages minimizes installation space and leakage risks.
 
------
 
5. Typical Applications
 
  • Construction Machinery: Crane outrigger synchronization, concrete pump boom control.
 
  • Agricultural Machinery: Combine header lifting, planter trench depth adjustment.
 
  • Industrial Equipment: Injection molding machine platen synchronization, die-casting machine clamping.
 
------
 
6. Selection & Installation Guide
 
  1. Flow Matching
 
      • Ensure input flow ≤ rated capacity (1.5 L/min); overloading may cause overheating or reduced accuracy.
 
  2. Pressure Matching
 
      • System max. pressure must be ≤350 bar; include a safety margin.
 
  3. Mounting Orientation
 
      • Vertical/horizontal mounting allowed; avoid port-down orientation to prevent debris accumulation.
 
  4. Maintenance
 
      • Replace oil filter every 500 hours; inspect gear wear periodically.

7. Troubleshooting
 
【表格】
 Symptom Possible Cause Solution
Uneven Division Gear wear, oil contamination Replace gears, clean valve, replace filter
Excessive Pressure Drop Input flow overload, internal leakage Reduce flow to rated value, check seals
Output Flow Fluctuation Load surge, compensator valve failure Optimize system load, repair/replace valve
