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.

超低溫蝶閥采用偏置閥桿和偏心蝶板設(shè)計(jì)，在開啟和處于中間位置時(shí)，閥座與蝶板不發(fā)生接觸，在減小扭矩的同時(shí)減少了對(duì)閥座的摩擦，提高了閥的耐久性，是一種高性能的調(diào)節(jié)、切斷型閥門。該閥門的設(shè)計(jì)旨在應(yīng)對(duì)當(dāng)今工業(yè)環(huán)境中最難以處理的各種介質(zhì)，包括液氧、液態(tài)天然氣和其他低溫液體。
