Application: Shut off the flow of silica sand from a product silo that discharges into a weigh hopper.
Both gates equipped with a full-length return pan on the discharge. This fabricated accessory is available for applications requiring zero external product leakage. Any material that migrates into the bonnet area of the valve is returned to the processing line.
Blades constructed from abrasion-resistant steel.
Challenge: Obtain a slide gate that withstands the abrasiveness of the material handled and will not leak product to atmosphere.
Results: The gates were installed in May 2005. To date, the gates have performed maintenance-free.
