Feature Description
This valve is suitable for use as an on-off device in pipeline systems conveying non-corrosive and corrosive media such as petrochemicals, petroleum, natural gas, steam, and others. Its nominal pressure ranges from 1.0 to 10 MPa, it operates at temperatures up to 15°C, and requires a supply air pressure of 0.6 to 0.8 MPa.
The sealing surface employs a hard seal, and the parts that come into contact with the medium are sealed using structural ceramic materials, which exhibit extremely high chemical stability and hardness. This valve boasts exceptional resistance to wear, corrosion, and erosion, ensuring a long service life.
