Primarily used in pipeline cutting systems for industries such as petroleum, natural gas, chemical engineering, power generation, and water treatment. It is particularly suitable for situations where high sealing performance is required and frequent operations are not necessary.
The structure is short in length and has low flow resistance; the sealing surface is less likely to be eroded when fully open; it can adopt metal hard sealing or soft sealing structures, and is suitable for high-temperature, high-pressure and corrosive media.
