Product Name:
GM Series Vacuum Diaphragm Valve Manual
Description:

GM手动真空隔膜阀


用途和使用范围:
  GM系列手动真空隔膜阀是在1.3×10-5~3×105Pa的真空系统中用来开启或隔断气流的阀门。

主要性能:
● 漏率:≤1×10-9Pa.M3/S;
● 材料:304、316L; 
● 工作介质:空气、水、酸、碱;
● 工作温度:氟橡胶-30℃~+150℃;

手动真空隔膜阀的原理:
转动螺杆使阀芯上下运动,同时拉动膜片上下运动,关闭和打开。

特点:
● 结构紧凑、简单、体积小,外形美观;
● 开关有导向,运动平稳;
● 关闭力矩小,寿命长,≥3万次;
● 膜片压紧可自动调整,受压均匀, 密封可靠;
● 膜片装入阀芯采用推入式,更换方便;
