These rectangular roller gates were constructed to match the customer’s flange pattern and feature a valve body constructed from 6061-T6 aluminum, and blade & material contact areas constructed from 304 stainless steel.
Gates are actuated using double-acting air cylinders.
Lower bonnet seals are live loaded and silicone rubber backed. Valves also include cam-adjustable slide rollers and PET roller spacers.
Milled access slots in the side frame allows removal and replacement of bonnet seals while the valves remain in service.
These Vortex Roller Gates are installed on a H&H Design Series 2000 Bulk Bag Discharge System. The gates are installed below the bag bottom support pan and are used to control flow into the flex augers.
