Product Description
The O type shut-off ball valve is a kind of quarter-turn on-off valve. It is mainly used for shut-off control of media. The ball valve of this series adopts round hole in the ball. When opened, it is directly connected to the body flow channel, featured by high flow capacity. Compared with plunger valves, it has small structural sizes, light weight and the function of self-cleaning between plug and seat. Therefore, it is very suitable for viscous, fibrous media and those containing suspended solid particles. With low heat expansion impact due to temperature, and good sealing performance, it is widely applied in the systems of such industries as petrochemical industry, metallurgy, chemical fiber, pulp & paper, medicine, hydroelectric station, etc. to meet the needs of remote control of process parameters such as flow, pressure, temperature and liquid level of all gases, liquids or corrosive gases and liquid media.
Compact structure: small volume, light weight, easy maintenance
Smooth flow channel: low flow resistance, low pressure drop, high flow
Strong anti-wear performance: The ball is subject to hard alloy spray coating, and the seat sealing face is subject to hard alloy overlaying welding.
Fire-safe and antistatic: Meeting API607 requirements, it is provided with the antistatic device.
