Smooth and flexible operation, small friction, long-term stable and flexible operation of the valve stem, even for the shrinkage ball valve, its fluid resistance is quite small;
|
Low resistance |
The structure is unreasonable, the valve resistance is large, the corresponding action is slow and inconvenient to use.
|
||
|
The sealing ring is made of elastic materials such as polytetrafluoroethylene, which is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure. The valve stem only rotates without lifting, so the packing seal is not easy to be damaged.
|
Sealed well |
The sealing materials are poor, easy to leak, polluting the environment and causing huge losses.
|
||
|
Because PTFE and other materials have good self-lubrication and small friction loss with the ball, their service life is at least 2 times longer than that of ordinary ball valves.
|
Long life |
Jerry work and rough products, bringing many troubles to production.
