In modern industrial production, fluid control is a key link to ensure the smooth progress of the production process. As an efficient and reliable fluid control device, the ear trunnion ball valve is widely used in multiple fields such as petroleum, chemical engineering, natural gas and water treatment due to its unique structural design and outstanding performance.

Efficient application in industrial fluid control

(I) Oil and Gas Industry

In the processes of oil and gas extraction, transportation, and processing, trunnion ball valves are widely used in the following scenarios:

Oil and Gas Transmission Pipelines: They are used to control the flow rate and direction of oil and gas, ensuring the safe operation of the pipeline system.

Wellhead Control: At the oil and gas wellheads, trunnion ball valves can quickly cut off the fluid to prevent accidents such as blowouts.

Natural Gas Liquefaction and Storage: In liquefied natural gas (LNG) plants, trunnion ball valves are used to control the flow of cryogenic liquids, ensuring the stable operation of the system.

(II) Chemical Industry

In chemical production, trunnion ball valves are used to control the flow of various chemical media, ensuring the safety and efficiency of the production process:

Reactor Feeding and Discharging: Trunnion ball valves can accurately control the feeding of chemical raw materials and the discharging of finished products, preventing leakage and contamination.

Pipeline Systems: They are used to control the flow of corrosive media such as acids, alkalis, and salts, reducing the corrosion of the pipeline system and maintenance costs.

(III) Water Treatment Industry

In water treatment systems, trunnion ball valves are used to control the flow rate and direction of water, ensuring the stable supply of water quality and quantity:

Water Plant Inlet and Outlet: Trunnion ball valves can quickly respond to changes in water level, controlling the flow rate of inlet and outlet water to ensure the normal operation of the water plant.

Sewage Treatment Plant: During the sewage treatment process, trunnion ball valves are used to control the discharge and reflux of sewage, preventing sewage leakage and environmental pollution.
