American standard forged steel ball valves are suitable for various pipelines ranging from Class150 to Class1500, PN16 to PN100, and JIS10K to JIS20K. They are used to cut off or connect the medium in the pipeline. Different materials are selected It can be respectively applied to various media such as water, steam, oil products, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc., and is widely used in the chemical, petroleum, natural gas, metallurgy and other industries.

The driving methods of American standard forged steel ball valves include worm gear and worm transmission, manual, pneumatic or electric. Fixed ball valves are generally connected by flanges, but can also be connected by butt welding. Applicable media: C: water, oil, steam; P: Nitric acid (temperature ≤200℃); R: Acetic acid (temperature ≤200℃). Structural features of American standard forged steel ball valve: Double blocking and discharge function, fireproof structure, sealing, emergency grease injection, rescue, reliable valve stem sealing

1. Double Blocking and Discharge Function: The American standard forged steel ball valve adopts a spring-loaded floating valve seat. When the valve is fully open or fully closed, the valve seats on the upstream and downstream sides block the fluid, and the retained substances in the valve body cavity are discharged through the discharge valve.

Second, automatic pressure relief function: When the temperature of the medium remaining in the valve cavity rises and causes abnormal pressure increase, it does not need to pass through the valve but can automatically relieve pressure solely by relying on the valve seat function. This is crucial for ensuring the safety of the valve when transporting liquid media.

Iii. Fireproof structure valves all have fireproof functions, and their design and manufacturing specifications are required.

4. Emergency grease injection for sealing rescue: In the event of accidental failure of the valve seat seal due to foreign objects in the medium or fire, the grease injection valve provides a quick connection with the grease injection gun, allowing for the convenient and rapid injection of sealing grease into the valve seat sealing area to alleviate leakage.

Five. Reliable valve stem Seal and low operating torque: In addition to setting standard sealing rings, an "O" ring seal is also installed on the packing gland. The double seal ensures the reliability of the valve stem seal. The addition of graphite packing and the injection of sealing grease reduced the leakage of the valve stem after the fire. The sliding bearing and thrust bearing of the valve stem make the valve easy to operate.

Six. Full bore or reduced bore: Full bore or reduced bore structures can be selected as needed. The flow diameter of the full-bore valve is consistent with the inner diameter of the pipeline, which is convenient for pipeline cleaning.

Seven. The valve stem can be lengthened. According to the requirements of installation or operation, the valve stem of the valve can be lengthened. The extended rod ball valve is particularly suitable for applications such as urban gas where pipelines need to be laid underground. The size of the extended valve stem is determined according to the customer's requirements.

Viii. The flexible American standard forged steel ball valve adopts valve seats and valve stem bearings with a small friction coefficient and good self-lubricating property, which greatly reduces the operating torque of the valve. Therefore, even without the provision of sealing grease, the valve can be operated flexibly and freely for a long time.

Ix. Multiple drive modes, easy to achieve automatic control. The drive mode is flexible, and the operation mode can be selected as manual, pneumatic, electric, pneumatic-hydraulic linkage, hydraulic, etc. according to needs.
