Introduction To Ball Valve

The opening and closing part of the ball valve is a sphere, which rotates 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off distribution and change the direction of medium flow on the pipeline

Ball valves have a wide range of applications, including high temperature and high pressure resistance, large diameter, high sealing, long service life, and excellent regulation performance. They partially replace gate valves, globe valves, and throttle valves, especially in oil and gas pipelines, oil refining and cracking devices, and nuclear industry. In addition, ball valves will also become one of the leading valve types in large and medium-sized medium and low pressure fields in other industries.

Advantage of Ball Valve

It has the lowest flow resistance (in fact, it is only equivalent to a section of circular pipe with the same nominal size)
It can be reliably used in corrosive media and low boiling point liquids because it will not get stuck during operation (when there is no lubricant)
Complete sealing can be achieved in a large pressure and temperature range
It can realize rapid opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to ensure that it can be used in the automation system of the test bench. When opening and closing the valve quickly, the operation has no impact.
The spherical closure can be automatically positioned at the boundary position.
The working medium can ensure reliable sealing at the inlet sealing seat
When fully open and fully closed, the sealing surface of the ball and valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface
Compact and light in weight, it can be considered the most reasonable valve structure for the low-temperature medium system
The valve body is symmetrical, which can well withstand the stress from the pipeline.
The closing part can withstand the high-pressure difference when closing

what is a full port ball valve?

Definition:

● the full diameter is the equal width channel, that is, the size of the channel from inflow to outflow is the same, and its size cannot be less than the value specified in the standard, which is roughly equivalent to the nominal diameter of this specification. For example, the channel diameter of DN50 full diameter ball valve is about 50

Applicable process:

for pipelines that need regular pigging, full bore ball valves must be used no matter what medium is conveyed.
the medium passing through the full bore ball valve will not reduce the flow, and the flow resistance is small. It is an ideal product for pipeline control, especially under strict working conditions.
when the main pipelines in oil and gas pipelines need to be buried underground, full bore welded ball valves need to be used.
