Oil Pipeline Applications
    Mounting Trunnion Ball Valves, High Pressure Trunnion Ball Valves, Forged Steel Trunnion Ball Valves and other products are widely used in the petroleum industry. Ball valves on petroleum pipelines play a key role in opening and closing, usually the valve size is 1/2 "~ 56" The pressure ranges from Class150 # ~ 2500 #. The material is made of forged steel, cast steel, stainless steel and other materials. The trunnion ball valve adopts fire prevention and antistatic design.
    Trunnion ball valves are an important part of industrial pipelines and play a vital role in the production efficiency of the petroleum industry. The trunnion ball valve plays an important role in adjusting the production speed, controlling production operation and ensuring production safety in the petroleum industry. In the industrial production process, because there are many factors to be considered, the selection of trunnion ball valves needs to be very careful and rigorous.

Gas Industry

    Fully Welded Ball Valve for the natural gas industry, API607 Fire Ball Valve, API6D Mounting Trunnion Ball Valve, widely used in natural gas pipelines to ensure the safety and reliability of gas
    Trunnion-type ball valves are indispensable in natural gas engineering pipelines. They are a new generation of high-performance ball valves that are suitable for long-distance pipelines and general industrial pipelines. Their strength, safety, and harsh environment resistance have been specially considered during design and applicable to various Corrosive and non-corrosive media. Compared with the floating ball valve, during operation,

Chemical Industry
    Chemical industry Mounting Trunnion Ball Valves, High Pressure Trunnion Ball Valves, Forged Steel Trunnion Ball Valves mainly plays the role of flow control. The chemical industry has high-dangerous materials and has high requirements for pipelines. Ball valves play a vital role in regulating the flow and cutting off safety in production.
    Fire protection structure: In order to prevent the PTFE seal ring from being burned due to sudden heat or fire, a large leak will occur, and to promote the fire, a fireproof seal ring is installed between the ball and the valve seat. Under the action of force, the valve seat sealing ring is quickly pushed onto the sphere to form a metal-to-metal seal, which plays a certain degree of sealing effect. The fire resistance test meets the requirements of AP16FA and APl607 standards.
Matching Equipment
Mounting trunnion ball valve is suitable for various pipes of Class150 ~ Class2500, PN16 ~ PN420, JIS 10K ~ JIS 160K, applicable temperature: -196 ~ 420 ℃, used to cut off or connect the medium in the pipeline. Material can be used for supporting equipments such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc. It is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electric power, municipal , Steel and other fields. Mounting trunnion ball valve is driven by worm gear, manual, pneumatic or electric. Fixed ball valves are generally connected by flanges, but also by butt welding.
Marine & Offshore Engineering
Marine equipment marine engineering mainly uses API607 Fire Ball Valve, API6D Mounting Trunnion Ball Valve, Nickel Aluminum Bronze Ball Valve, C95800 Ball Valve.
Marine ship engineering has relatively high requirements for anticorrosion. Special materials such as duplex stainless steel, nickel-aluminum bronze, titanium alloy, copper-nickel alloy, Monel, Hastelloy are often used to meet the application in special conditions.。
Water Treatmen
    Water treatment is applied to Mounting Trunnion Ball Valve, Electric Trunnion Ball Valve, Cast Steel Trunnion Ball Valve, Floating Ball Valve, etc. Sewage treatment, drinking water pipeline.
    Flexible operation: The valve seat and valve stem bearing with small friction coefficient and good self-lubrication greatly reduce the operating torque of the valve. Therefore, it is possible to operate the valve flexibly for a long period of time even without providing sealing grease.
    Full diameter or reduced diameter: Full diameter or reduced diameter structure can be selected as required. The full-bore valve's flow aperture is consistent with the inside diameter of the pipeline, making it easy to clean the pipeline.
