A Check Valve, also known as a non-return valve or one-way valve, is a mechanical device designed to control the direction of fluid flow within a system. It consists of a valve body, which contains an opening or passage, and a movable closure element, such as a disk, ball, or flapper, that is positioned to allow flow in one direction and block it in the other. Attributes:• Ensures brake fluid flows in one direction.• Prevents brake system backflow.• Allows brake fluid to flow in one direction only.• Prevents air or fluid from entering the brake lines.• Crack pressure is 35 kilopascals.Applications:A Check Valve is used in the brake control valve to prevent the reverse flow of brake fluid, maintaining pressure and ensuring that brakes engage quickly and reliably.
