Component Specifications

Definition
The Lower Plate/Moving Plate is a critical sliding component in slide gate flow control systems, designed to precisely regulate the flow of materials (powders, granules, liquids) through controlled linear displacement. This plate interfaces with a stationary upper plate to create adjustable openings, enabling accurate flow modulation in industrial processes.
Working Principle
Operates through linear sliding motion along precision guides or rails, creating variable apertures between the moving plate and stationary counterpart. Hydraulic or pneumatic actuators typically drive the plate's position, with position feedback systems ensuring precise flow control. The plate's movement directly correlates to flow area, following proportional control principles.
Materials
High-wear resistant materials: 304/316 stainless steel (food/pharma), hardened tool steel (abrasive materials), tungsten carbide coatings (extreme wear), ceramic composites (corrosive environments). Surface finishes: Ra ≤ 0.8μm for sealing surfaces.
Technical Parameters
  • Thickness 10-50 mm
  • Actuation force 500-5000 N
  • Pressure rating Up to 10 bar
  • Surface hardness HRC 45-60
  • Flatness tolerance ≤ 0.05 mm/m
  • Operating temperature -20°C to 400°C
Standards
ISO 12100, ISO 13849, DIN 2458, DIN 2501
