Used to cut off or connect the medium in the pipeline, choose different materials, which can be used to transport water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc., widely used in petroleum refining, long-distance pipelines , Chemical, paper, pharmaceutical, water conservancy, power, municipal, steel and other fields.

Advantages:

1. Sealing emergency grease injection rescue: due to foreign matter in the medium or fire causing the valve seat seal to fail unexpectedly, the grease injection valve provides a quick connection with the grease injection gun, and the imported pump can easily and quickly inject the sealing grease into the valve seat sealing part. Mitigating leakage.

2. Reliable valve stem sealing and low operating torque: In addition to the standard sealing ring, an O-ring seal is also set on the packing gland. The double seal ensures the reliability of the valve stem seal; additional graphite packing and sealing grease Injection minimizes valve stem leakage after a fire. The valve stem sliding bearing and thrust bearing make the valve easy to operate.

3. Full diameter or reduced diameter: Full diameter or reduced diameter structure can be selected according to needs. The flow aperture of the full-bore valve is the same as the inner diameter of the pipeline, which is convenient for pipeline cleaning.

4. The valve stem can be lengthened: According to the needs of installation or operation, the valve stem can be lengthened. The extended stem ball valve is especially suitable for occasions where pipelines need to be buried in the ground, such as city gas. The size of the lengthened stem is determined according to customer needs.

5. Flexible operation: The valve seat and stem bearing with small friction coefficient and good self-lubricating property are adopted, which greatly reduces the operating torque of the valve. Therefore, even in the absence of sealing grease, the valve can be operated flexibly for a long time.
