真空球阀概述
LIT型系列真空(压力)球阀是适用于真空系统中接通或切断管路的介质流。该阀为直通式手动球阀，靠球面密封，因而既能用在真空状态下，也能在低压状态下使用，并可任意位置安装。
Vacuum ball valve (pressure) is applied to the vacuum system is turned on or cut off the pipeline medium flows. The valve straight-through manual valve relies on spherical seal, which both used in the vacuum state, can be used at low pressure and can be installed anywhere
适用的工作介质为带酸、碱性的气体或液体
