GDC-J型高真空電磁板閥 Electro High Vacuum Flapper Valve是連接在真空管路上，用來接通或截止真空系統中的氣流，或作充氣閥用。永嘉縣科本真空閥門廠的GDC-J型高真空電磁板閥當通電時將P、A端管路接通、斷電時切斷P、A端管路，保持P端真空系統的真空度。GDC-J型高真空電磁板閥適用介質為純凈空氣和非腐蝕性氣體。

GDC electro high vacuum flapper valve is mounted in vacuum pipeline to put through or cut off the airflow in vacuum system, or used as a charging vale. When power is connected, pipes at P and A will be put through, and when power is disconnected, pipes at P and A will be cut off, to keep the vacuum system at P vacuum. Applicable medium can be pure air and noncorrosive gases.
