真空球閥概述
LIT型系列真空(壓力)球閥是適用于真空系統(tǒng)中接通或切斷管路的介質(zhì)流。該閥為直通式手動(dòng)球閥,靠球面密封,因而既能用在真空狀態(tài)下,也能在低壓狀態(tài)下使用,并可任意位置安裝。
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
適用的工作介質(zhì)為帶酸、堿性的氣體或液體
