Ball valve features
Advantages:
- Has the lowest flow resistance (actually 0)
- Can be reliably used in corrosive media and low-boiling liquids
- It can achieve complete sealing in a large pressure and temperature range
- Can achieve fast opening and closing, no impact operation
- the spherical closure can be automatically positioned at the boundary position
- the working medium is reliably sealed on both sides
- the medium passing through the valve at high speed will not cause corrosion of the sealing surface
- Compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system
- the valve body is symmetrical, especially the welded valve body structure, can well bear the stress from the pipeline
- the closing piece can withstand the high pressure difference when closing
- the ball valve with fully welded body can be buried directly underground, so that the internal parts of the valve are not eroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines.
