Discharge Valve

For use Above Rotary Airlock to Prevent Pressure from Returning to the Hopper above.

Pneumatic actuated Discharge Valve for gravity flow applications. Blade is sealed to differential pressures up to 15 psig top to bottom depending on the size of the gates. For use above rotary airlock to maintain pressures in the line below and eliminate air loss promoting continuous material conveyance.
