The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.
The Concentric butterfly valve is an industrial valve used for the on-off and flow control of pipeline systems. It is widely applied in fields such as petroleum, chemical industry, metallurgy, and hydropower. Its core structural feature is that the axis of the valve stem, the center of the butterfly plate, and the center of the body are on the same axis, featuring simple manufacturing and balanced opening and closing torque. By selecting different materials for the valve plate, valve stem, and sealing seat, it can be adapted to various different working environments, such as desulfurization, vacuum, and seawater desalination systems.
