Product Features

1. Low fluid resistance

Low fluid resistance. The fluid resistance of ball valves is the smallest among all valves, even for shrink ball valves, their fluid resistance is 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 its excellent self-lubricating properties and low friction loss with ball valves, PTFE has a long service life for ball valves.

Advantages of butt welded ball valves

1. Low fluid resistance. The internal medium channel of the valve body is straight through, and the medium flows in a straight line with low fluid resistance.

2. It is more effortless to open and close. Compared to globe valves, this is because regardless of whether it is open or closed, the direction of movement of the gate is the same

Vertical to the direction of medium flow.

3. High height, long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lowering is carried out through the screw.

4. Water hammer phenomenon is not easy to occur. The reason is that the shutdown time is long.

7. Simple form, short structural length, good manufacturing process, and wide applicability.

8. Compact structure, good valve rigidity, smooth channel, low fluid resistance, sealing surface made of stainless steel and hard alloy, long service life, using PTEF packing, reliable sealing, easy and flexible operation.
