The closure component of a butt-welding ball valve is a ball, which achieves opening and closing by rotating 90° around the centerline of the valve body. Straight-through ball valves are primarily used in pipelines for cutting off media. They come in two-piece and three-piece designs, and the butt welding methods include socket welding, groove welding, and flat welding. Butt-welding ball valves are a new type of valve that has been widely adopted in recent years, and they can be installed horizontally or vertically.

Product Features

1. Low fluid resistance

Low fluid resistance. The fluid resistance of a ball valve is the smallest among all valves, and even for a contracted ball valve, its fluid resistance is also very small.

2. Good sealing

A good sealing seat. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.

3. Good self-lubrication

Due to PTFE's excellent self-lubricating properties, there is minimal friction loss with the ball valve, resulting in a long service life for the ball valve.

Advantages of welded ball valve

1. Low fluid resistance. The internal medium passage of the valve body is straight, allowing the medium to flow in a straight line, resulting in low fluid resistance.

2. It requires less effort to open and close. This is compared to a globe valve, because whether it is opened or closed, the direction of movement of the gate plate is consistent

Perpendicular to the direction of medium flow.

3. High in height and long in opening and closing time. The gate plate has a large opening and closing stroke, and the lowering is achieved through a screw rod.

4. The water hammer phenomenon is less likely to occur due to the long closing time.

7. Simple shape, short structural length, good manufacturing process, and wide range of applications.

8. Compact structure, good valve rigidity, smooth passage, low fluid resistance, and sealing surface made of stainless steel and

Cemented carbide, with a long service life, utilizes PTFE packing for reliable sealing and offers lightweight and flexible operation.
