The Valve Spool, a cylindrical part with intricately designed channels and lands, is positioned within the valve housing. It is responsible for controlling the flow of hydraulic fluid that affects the brake pressure. Alongside the spool, a slug is situated. The movement of the spool influences the position of the slug. In brake control valves, the Valve Spool, Slug, and Plunger work together to regulate hydraulic pressure and facilitate precise control of the braking unit. This assembly interfaces with the hydraulic system and responds to changes in hydraulic pressure. As the spool moves, it affects the position of the slug, which in turn adjusts the pressure applied to the plunger.
Attributes:
• Determines the amount of hydraulic pressure transmitted to the brake mechanism
• Provides a controlled braking force being applied to the machine's wheels
• Allows for fine-tuning of the braking system's responsiveness and effectiveness
Applications:
The Valve Spool is used in the Brake Control Unit to enable safe and reliable braking performance by regulating hydraulic pressure accurately based on driver input, As the spool moves, it affects the position of the slug, which in turn adjusts the pressure applied to the plunger.
