Manual Ball Valve :
A manual ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control the flow of a fluid through it. The valve is operated by rotating the ball 90 degrees, which either allows the fluid to flow through the hole or blocks it, depending on the position of the ball. Manual ball valves are widely used in various industries and applications due to their simplicity, reliability, and ease of operation.
Here are some key features and applications of manual ball valves:
Quarter-Turn Operation: Manual ball valves operate on a quarter-turn principle, meaning the valve is either fully open or fully closed with a 90-degree rotation.
Ball Design: The ball inside the valve has a bore or port through which the fluid flows. When the ball is rotated, the bore aligns with the flow path, allowing the fluid to pass, or it can be turned to block the flow.
Handle or Lever Operation: Manual ball valves typically have a handle or lever attached to the ball, allowing for easy manual operation. The handle is usually perpendicular to the flow when the valve is closed and parallel when open.
Variety of Materials: Manual ball valves are available in various materials, including brass, stainless steel, PVC, and other alloys, to suit different applications and environments.
Pressure Ratings: Manual ball valves can handle a wide range of pressure ratings, making them suitable for applications with varying pressure conditions.
Applications:
General Plumbing: Manual ball valves are commonly used in residential and commercial plumbing systems for controlling the flow of water in pipelines.
Industrial Processes: They are widely used in industrial settings for controlling the flow of various fluids, including chemicals, gases, and liquids.
Oil and Gas Industry: Manual ball valves play a crucial role in the oil and gas industry, where they are used for isolation and control in pipelines and equipment.
Chemical Processing: In chemical plants, manual ball valves are employed to control the flow of corrosive or hazardous chemicals.
Agricultural Applications: They are used in irrigation systems and agricultural equipment for fluid control.
Marine and Shipbuilding: Manual ball valves find applications in marine systems and shipbuilding for controlling fluid flow.
