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.
RAYS Top Entry Cryogenic C-Type Ball Valve is a specially designed ball valve suitable for ultra-low temperature environments, especially for the control of cryogenic fluid media such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen. The characteristic of the top entry C-Type C-Type ball valve lies in its special structural design.
The Cryogenic High-Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
