The Cryogenic Temperature and 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.

Three eccentric butterfly valve series is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
