Products Details

Hard sealed flanged ball valve is a kind of valve widely used in industrial field, it has a variety of characteristics and application scenarios. Here are some of the key features and applications of hard sealed flanged ball valves:

Adaptability: Hard sealed ball valve can adapt to a wider range of temperature and fluid medium, safe and reliable seal under working conditions, long service life, easy operation, and small pressure loss.

Sealing performance: Compared with soft sealing ball valves, hard sealing ball valves have superior sealing performance under high temperature, high pressure, highly corrosive media and working conditions containing granular media.

Structural characteristics: The structural characteristics of the hard sealed ball valve include a hard seal between the ball and the seat, the fixed type has a two-way seal and discharge function, the middle chamber has a pressure self-leakage function, the anti-ejection valve stem, has a dust and self-cleaning function, and an anti-static device.

Material range: The product range of hard sealed ball valve includes carbon steel, stainless steel, alloy steel and duplex steel, and the sealing material includes carbon steel, stainless steel and duplex steel.

Application: Hard sealed ball valve is widely used in petroleum, chemical, electric power, pharmaceutical, food processing and other industries, especially suitable for power station, metallurgical industrial boiler, coal, scale or frozen pipeline containing particles or fiber media control.

Working principle: The hard sealed ball valve is sealed in various pipeline systems and is used to cut off or connect the medium flow, so that the medium can be transported to the specified point in accordance with the predetermined procedure.

Fluid resistance: The fluid resistance of the hard sealed ball valve is small, and the full-caliber ball valve basically has no flow resistance.

Maintenance: Hard seal ball valve structure is simple, easy to maintain, sealing ring is usually movable, disassembly and replacement is relatively easy.

Seal type: hard seal ball valve seal can be divided into one-way seal and two-way seal, one-way seal can only be sealed in the specified direction, and two-way seal can be sealed in both directions.

Temperature and pressure range: Hard sealed ball valves are suitable for high temperature and high pressure water, steam, oil, coal, fiber and corrosive media, as well as media containing particles.

Through these characteristics, we can see the importance and reliability of hard sealed flanged ball valves in industrial applications.
