High Vacuum
Flapper Valve | | | | | ■ | GD high vacuum flapper valve is
used to put through or cut off the airflow in vacuum pipeline. Applicable medium
can be pure air and noncorrosive gases. According to its shaft seal structure,
high vacuum flapper valve is classified into GD-J rubber shaft seal type and
GD-J(b)bellows shaft seal type. According to its put-through type, it is
classified into GD-J angle type and GD-S three-way type with prepumping. |
