XC (SER.14) - Hopper shape silo outlet


The XC model knife gate is a wafer valve designed for industrial bulk handling service applications (powdered and granular products). The special design of the body allows for easy passage of the fluid and makes it ideal for use as silo outlet valve. Widely used in industries such as:

  • Power plants
  • Food and Beverage
  • Chemical plants
  • Mining
  • Etc.

Valve is usually installed under silos or hoppers in vertical pipes with the seat in the upstream side of the valve in order to protect it from the solids flow. This set up helps to protect the seat from premature wear and gate jamming due to solid build-up.
