Ball Features:

1, the seat with double lip seal design, enhanced sealing performance and reduce operating torque. A variety of seat materials, adapt to a wide range;

2, stem-proof design: Stem for download type, to prevent fly compression, while using PTFE material-oriented, reduce stem friction and reduce operating torque;

3, fire anti-static design; at the same time can be designed according to specific customer requirements in the form of structure or use conditions. High platform structure can be directly mounted drive.

球阀特点：

1、阀座采用双唇密封结构设计，增强密封性能，降低操作扭矩。多种阀座材料，适应范围广；

2、阀杆防爆结构设计：阀杆为下装式，防止受压飞出，同时采用四氟材料导向，减少阀杆摩擦，降低操作扭矩；

3、防火防静电结构设计；同时可根据客户要求或使用工况设计特定的结构形式。高平台结构可直装驱动装置。
