Description:
A valve ball is a type of valve component used in flow control systems. It is a spherical ball-shaped component that is designed to be rotated inside a valve body to regulate the flow of fluid or gas through the valve. When the valve is in the open position, the ball is rotated to allow the fluid or gas to flow through the valve body. When the valve is closed, the ball is rotated so that it blocks the flow of fluid or gas.

Attributes:
• Operated manually.
• Handle a specified flow rate of a fluid.
• Ability to withstand the properties of the fluid being controlled, such as temperature, pressure, and corrosiveness.

Applications:
A valve ball is used in fuel injection systems to regulate the flow of fuel into the engine. They are extensively used in Cat 990H, 990K, 993K - Wheel-type loader, 631E, 631G, 633E, 637E, 637G, 651E, 657E, 657G - Wheel Tractor-Scraper, 844H, 844K - Wheel Dozer, 533, 543, 559C, 579C, HA770, HA771, HA870, HA871, TK370, TK371, TK380, TK381, 2384C, 2484C - Forest Products and 58L, 59L, 59N, 8 8A, 8S 9, 9SU, 9U, D10N, D10R, D10T, D11N, D11R, D11T - Track-type Tractor.
