Ball Valve
Siken Hydraulics provides accumulator ballvalves used for many applications.A ball valve is a type of valve that uses a ball-shaped disc to control the flow of fluid. The ball inside the valve has a hole or passage through its center, which allows or blocks the flow of the fluid when the valve is rotated. When the ball is positioned with the hole aligned with the flow direction, the valve is open, and fluid can pass through. When the ball is rotated to a position where the hole is perpendicular to the flow direction, the valve is closed, and fluid flow is blocked. Ball valves are commonly used in various industries for their reliable sealing, durability, and ease of operation.
