真空插板閥 Manual Ultra-high Vacuum Gate Valve
手動真空插板閥是以手柄帶動閥板作上下運動使閥板開啟或關閉。真空閥門用于接通或切斷真空管路中的氣流。真空插板閥適用介質為純凈空氣和非腐蝕性氣體。 永嘉縣科本真空閥門廠是中國泵閥產業集群“中國泵閥之鄉—溫州甌北”里專業從事真空閥門研制開發、制造生產、銷售服務為一體的專業真空閥門廠。電話：0577-67318321
manual ultra-high vacuum gate valve uses a handle to drive valve disc up and down to perform open and close action. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.
