GDQ-J/Z Series
Pneumatic High-Vacuum Flapper Valve
GDQ-J/Z Pneumatic High-Vacuum Flapper Valve relies on the electromagnetic directional valve to change the gas flowing direction and control the gas cylinder movement.When power or compressed air is lost,the valve will close automatically by means of the valve to connect or cut off the sirflow in the vacuum pipeline.The applicable media include clean air or non-corrosive gases.It's optionsal for a signal feedback device. |
