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.
超低温蝶阀采用偏置阀杆和偏心蝶板设计，在开启和处于中间位置时，阀座与蝶板不发生接触，在减小扭矩的同时减少了对阀座的摩擦，提高了阀的耐久性，是一种高性能的调节、切断型阀门。该阀门的设计旨在应对当今工业环境中最难以处理的各种介质，包括液氧、液态天然气和其他低温液体。
