Gate/Seal mechanism for precise powder flow control in hopper valves

View Specifications

Component Specifications

Definition
A mechanical assembly in powder hopper valves that regulates material discharge through an adjustable gate opening with integrated sealing surfaces to prevent leakage and ensure controlled powder flow in industrial processes.
Working Principle
Operates via linear or rotary motion to adjust gate position, creating variable apertures for powder flow while maintaining seal integrity through compression or interference fit against mating surfaces.
Materials
Stainless steel (304/316), food-grade polymers (PTFE, UHMW-PE), wear-resistant alloys (hardened steel, tungsten carbide coatings)
Technical Parameters
  • Actuation Manual/Pneumatic/Electric
  • Seal Type Compression/Inflatable
  • Leakage Rate <0.1% of flow
  • Temperature Range -20°C to 200°C
  • Gate Opening Range 0-100mm
  • Operating Pressure 0-10 bar
Standards
ISO 5211, DIN 3337, ISO 14119
