This series butterfly valve used worm drive ,operation of the LRT and self-locking function.
Application of advanced structural design of three eccentric and flexible ring of tiny elastic deformation characteristics , the use of advanced technology and methods for process equipment manufacturing , to ensure accuracy of parts and assembly accuracy .Ensuring reliable seal a lasting pay coincide with the total elimination of the sealing surface of the interference with the mill loss . Therefore , the switch resistance small , reliable sealing , sealing surface wear small , whole working life long .
The products are widely used in metallurgical , petrochemical , oil refining , to the drainage works and other sectors.

本系列蝶阀采用蜗杆传动，操作轻便，具有自锁功能。

应用先进的三偏心结构设计和灵活的小环弹性变形的特点,使用先进的技术和方法过程设备制造,以保证零件精度和装配精度.Ensuring可靠密封持久支付配合密封表面的总消除干扰机的损失。因此，开关电阻小，密封可靠，密封面磨损小，整个工作寿命长。

产品广泛应用于冶金、石化、炼油、给排水等行业。
