Electro High Vacuum Flapper Valve

■ GDC-5 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.
