Bulk Material Unloading

Manual and Automatic Bulk Bag Unloading Equipment Bag V-Form Close Off Valve Option

The V-form valve option on the UltiMAX bulk bag unloaders provides a means to seal the bag off and re-tie or to simply stop the flow of material to the process. The valve is actuated with two pneumatic cylinders that move the v-shaped rounded bars toward each other. This pinches bag outlet spout tightly and stops flow out of the bulk bag. The v-shaped bars are made from solid stainless steel. The standard valve is operated by a manual 3-position pneumatic toggle lever valve.  The valve is also available in an electrically controlled version for use in automated systems.  



  • Allows for closure and retying of a partially empty bulk bag outlet spout.  
  • Rounded to prevent damage to bulk bag outlet spout
  • Can close off most materials with or without product flow.
  • Dual 3” diameter pneumatic cylinders
  • Manual or electric actuation
  • Reduces operator exposure to dust or hazzardous materials when used with our Untie Box Option or our Pinch Ring Option.
