The many unique characteristics of the ball valve wholesale determine that the ball valve is used in a relatively wide range of applications. Generally, in the double position adjustment, strict sealing performance, mud, wear, shrinkage channel, rapid opening and closing action (1/4 turn opening and closing), high Ball valves are recommended for pipeline systems with cut-off (large differential pressure), low noise, cavitation and vaporization, a small amount of leakage into the atmosphere, low operating torque, and low fluid resistance.
2PC ball valve is also suitable for piping systems with a light structure, low-pressure cut-off (small pressure difference), and corrosive media. Ball valves can also be used in low temperature (cryogenic) devices and piping systems. In the oxygen pipeline system in the metallurgical industry, it is necessary to use a ball valve that has undergone strict degreasing treatment. When the main pipeline in the oil pipeline and gas pipeline needs to be buried underground, a full-diameter welded ball valve should be used. When regulating performance is required, a ball valve with a special structure with a V-shaped opening needs to 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.
2PC Ball Valve
The applicable principles of china ball valve for sale:
For the main pipelines for oil and natural gas and those that need to be cleaned and buried underground, select a ball valve with a full-diameter and full-welded structure;
Buried in the ground, select the ball valve with full-diameter welding connection or flange connection; branch pipe, select the flange connection, welding connection, full-diameter, or reduced-diameter ball valve.
Flanged ball valves are used for the transportation pipeline and storage equipment of refined oil.
On city gas and natural gas pipelines, floating ball valves with flange connection and internal thread connection are selected.
In the oxygen pipeline system in the metallurgical system, it is advisable to use a fixed ball valve that is strictly degreased and flanged.
For piping systems and devices of low-temperature media, low-temperature ball valves with bonnets should be used.
On the pipeline system of the catalytic cracking device of the oil refining device, a lifting rod type ball valve can be selected.
In the equipment and piping system of the acidic and alkali corrosive media in the chemical system, it is appropriate to select all-stainless steel ball valves made of austenitic stainless steel with PTFE as the seat ring.
Metallurgical systems, electric power systems, petrochemical installations, and high-temperature medium piping systems or devices in urban heating systems can be metal-to-metal sealed ball valves.
When flow adjustment is required, worm gear drive, pneumatic, or electric regulating ball valve with V-shaped opening can be selected.
The use of ball valves is very extensive, and the variety and number of users continue to expand, and the development of high pressure, high temperature, large diameter, high sealing, long life, excellent adjustment performance and multi-function valve, its reliability and other performance indicators All have reached a high level, and have partially replaced gate valves, globe valves, and regulating valves.
With the advancement of ball valve technology, it will be more widely used in the foreseeable short period of time, especially in oil and gas pipelines, oil refinery cracking units, and the nuclear industry. In addition, in the large and medium caliber, low and medium pressure fields in other industries, ball valves will also become one of the leading valve types.
