GU series vacuum ball valve manual
Description:

手动真空球阀 GU

 

用途和使用范围:
GU系列手动真空球阀是在1.3×10-7~6×105Pa的真空系统中用来开启或隔断气流的阀门,广泛适用各类气体,液体等正、负压力管道系统,符合GMP标准。
主要性能:
● 漏率:阀体 ≤1.3×10-9Pa.M3/S;
● 压力范围:1.3×10-7Pa~6×105Pa;
● 工作介质:水、蒸气、酸、碱。
● 工作温度:-30℃~+150℃。
● 安装位置:任意。
● 寿命:≥20000次。
GU系列手动真空球阀的工作原理:
以阀杆带动阀球转 90º达到开关目的。

特点:
● 密封结构设计独特,漏率可达到<1×10-10Pa.M3/S,
改变了球阀不能满足高真空、超高真空的现状;
● 开关扭矩小,工作稳定、可靠;
● 结构紧凑,重量轻,外形简洁、美观;
● 该阀既能适用高真空,又能适用一定的正压力下 使用;
由于球阀全通导,又能达到超高真空要求,所以 也能适用于加速器真空系统。
主要零件材料:
阀体   304、316L
球体   316L
密封件  增强聚四氟乙烯

外形连接尺寸:
快卸法兰连接尺寸 (标准:GB4982)
