A Piston Barrel Valve Disc is used to regulate the flow of hydraulic fluid within the unit, providing accurate metering and direction of hydraulic pressure. The disc houses the piston inside the pump barrel ensuring proper alignment of the piston. The sealing surfaces are to create a reliable seal when in contact with other components.

Attributes:
• Ensures precise control and direction of hydraulic pressure
• Withstands high temperature and pressure of the hydraulic fluid without deformation

Applications:
A Piston Barrel Valve Disc is responsible for maintaining the required pressure levels within the pump, allowing the fluid to flow in the desired direction, whether to engage or disengage hydraulic components.
