Cast Diverter Valves /   Fabricated Diverter Valves
Diverter valves rerout materials from one discharge point to another.  Our line includes gravity diverter valve models and many more.  1" to 30" in cast models, 6" to 12" in fabricated models.

Knife Gate Valves:
The knife gate valve provides quick and efficient control of a wide range of materials in chemical plants, pulp and paper mills, wastewater treatment plants, mining operations, sugar mills and
food processing facilities.  Standard sizes from 2" to 72"
Slide Gate Valves:
The slide gate valve or knife gate valve provides quick and efficient method for isolating and controlling the flow of materials.  4" to 48"

Double Dump Valves:
The double dump valve is commonly used in pneumatic applications where a rotary valve is not suitable due to leakage.  6" to 12"

Positive Displacement Rotary Blowers:
Sunco is a leading distributor of positive displacement blowers from such respected manufacturers as Gardner Denver DuroFlow, Gardner Denver Sutorbilt and Dresser Roots.
Blower Packages:
Sunco blower units are available for positive pressure and vacuum applications, 20 to 5000CFM.

Bulk Bag Unloaders:
Sunco bulk bag unloader stations provide convenient, safe and dust-free method for handling and discharging bulk bags.

Bin Activators:
Bin activators mount to the bottom of silos and hoppers to promote the uniform flow of materials that typically do not discharge well.

Screw Conveyors:
We manufacture custom screw conveyor units for efficient movement of a wide range of dry material products. 

Pneumatic Conveyors:
Sunco Powder can provide complete pneumatic conveyor systems (pressure conveyer or vacuum conveyor ) for truck and railcar unloading, bulk storage, in-plant transfer as well as bin and mixer filling. 
Use the links below to go directly to more specific information on these conveyor types:
  • Vacuum Unloading System This system is used for short distances where high rates are not required. It is a reliable low cost system and is normally used to convey a product from one point to another.
  • Pressure System   Low, medium and high capacities requirements can use this type of system for short runs up to 500 feet.
  • Vacuum Pressure System  This system is a combination of both the vacuum and

  • pressure systems and provides unloading and transfer of a product from one point to another or from one point to several destination points.
