LDR-10550062 | Genuine CNH® Control Valve For New Holland T4030F, T4050F

Controls how much fluid passes through a system—slowing, increasing, or stopping flow as needed.

2. Control Pressure

Maintains safe and consistent pressure levels by opening or closing based on system demand.

3. Direct Fluid Movement

Routes fluid to different parts of a system (common in hydraulics and pneumatics).

4. Maintain System Stability

Prevents sudden pressure spikes, overloads, or flow surges that could damage components.

5. Automate System Operations

Many control valves are automatic or electronically controlled, improving efficiency and reducing manual adjustments.

6. Improve Safety

Ensures machinery or brake systems work properly by keeping fluid conditions stable and predictable.

1. Inconsistent or Unstable Operation

• Pressure or flow levels fluctuate

• Equipment behaves unpredictably

• System can’t hold a steady setting

2. Leaks

• Fluid leaking around the valve body

• Air hissing from pneumatic valves
  Leaks usually mean worn seals or internal damage.

3. Slow Response or No Response

• Valve opens or closes too slowly

• Takes too long to build pressure or move fluid

• Valve doesn’t activate when commanded

4. Unusual Noises

• Hissing

• Grinding

• Clicking

• Chattering

These noises often indicate internal wear, sticking, or debris inside the valve.

5. Loss of Pressure or Weak System Performance

• Hydraulic systems feel weak

• Air brake systems build pressure slowly

• Machines struggle to operate normally

This happens when the valve can’t regulate flow properly.

6. Overheating Components

Poor control valve operation can create:

• Excess heat in hydraulic circuits

• Overworked pumps or compressors

7. Incorrect Direction or Flow

• Fluid goes the wrong way

• Actuators move in reverse or not at all

• System behaves opposite of the control input

Often caused by internal sticking or failed solenoids.

8. Warning Lights or Fault Codes (in electronic systems)

Electronic control valves may trigger:

• System fault codes

• Warning lamps

• Reduced power mode
