Application field of ball valve

Posted by Bundor valve
Bundor Valve will introduces the applications of ball valves for you.
Many unique characteristics of the ball valve determine the relatively wide application of the ball valve. Generally, it is recommended use ball valves in the pipeline system with double position adjustment, strict sealing performance, mud, wear, necking channel, quick opening and closing action (1 / 4 turn to open and close), high-pressure cut-off (large pressure difference), low noise, cavitation and gasification, small amount of leakage to the atmosphere, small operating torque and small fluid resistance .
Ball valves are also suitable for piping systems with light construction, low pressure cut-off (small pressure difference), and corrosive media. Ball valves can also be used in low temperature (cryogenic) device and piping systems. In the oxygen piping system of the metallurgical industry, a ball valve with strict degreasing treatment should be used. When the oil pipelines and gas pipelines need to be buried underground, full bore welded ball valves are required. When adjustment performance is required, a ball valve of special structure with V-shaped opening should be selected. In petroleum, petrochemical, chemical, electric power, and urban construction, metal-to-metal sealed ball valves can be used for piping systems with operating temperatures above 200 degrees.
 
Where is the ball valve used? Applicable principle of ball valve
 
For the main pipeline of oil and natural gas transportation, if the pipeline needs to be cleaned and buried underground, the ball valve with full bore and fully-welded structure should be selected;
 
For those buried on the ground, the ball valve with all-way welding connection or flange connection should be selected; for branch pipe, the ball valve with flange connection, welding connection and all-way or reduced diameter should be selected.
 
For the transportation pipeline and storage equipment of product oil, the ball valve with flange connection should be selected.
 
In the pipeline of city gas and natural gas, the floating ball valve with flange connection and internal thread connection is selected.
 
In the oxygen pipeline system of metallurgical system, the ball valve with strict degreasing treatment and flange connection should be selected.
 
For piping systems and devices of low-temperature media, low-temperature ball valves with bonnets should be used.
 
The ball valve with lifting rod can be used in the pipeline system of the catalytic cracking unit of the oil refining unit.
 
In the devices and piping systems of corrosive media such as acid and alkali in chemical systems, all stainless steel ball valves made of austenitic stainless steel with polytetrafluoroethylene as the seat seal ring should be used.
 
For metallurgical systems, power systems, petrochemical installations, and piping systems or devices of high-temperature media in urban heating systems, metal-to-metal sealed ball valves can be selected.
 
When it is necessary to adjust the flow, it can choose worm gear drive, pneumatic or electric regulating ball valve with V-shaped opening.
 
 
summary
 
The use of ball valves is very extensive, and the variety and quantity of use are still expanding. It is developing towards high pressure, high temperature, large mouth diameter, high sealing, long life, excellent regulating performance, and multi-function direction of a valve. Its reliability and other performance indicators have reached a high level, and they can partially replace gate valves, globe valves and regulating valves.
 
With the advancement of ball valve technology, it will be more widely used in the foreseeable short term, especially in oil and gas pipelines, refinery cracking devices and the nuclear industry. In addition, the ball valve will also become one of the leading valve types in the field of large and medium caliber, medium and low pressure in other industries.
