GM高真空压力隔膜阀概述
GM High Vacuum(Pressure)Diaphragm Valve
真空隔膜阀GM是三精阀门型设计开发供接通或切断真空系统之用的真空阀门。连接管焊接式真空隔膜阀更是溴化锂制冷设备中的理想配件。高真空隔膜阀的适用介质为空气及非腐蚀性气体。连接法兰标准按GB6070或GB4982规定，也可为连接管焊接型式。
GM vacuum diaphragm valve is a vacuum valve designed and developed by Yongjia Keben Vacuum Valve Factory for connecting or cutting off the vacuum system. The connecting tube soldering vacuum diaphragm valve is an ideal accessory for lithium bromide refrigeration equipment. The suitable medium for high vacuum diaphragm valves is air and non corrosive gases. Connection flange standard according to GB6070 or GB4982, also can be connection pipe welding type.
