Industry-Verified Manufacturing Data (2026)

Gate or Valve

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Gate or Valve used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Gate or Valve is characterized by the integration of Gate Plate and Actuator. In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A flow control device for regulating material discharge from a feed hopper.

Product Specifications

Technical details and manufacturing context for Gate or Valve

Definition
A mechanical component installed at the discharge outlet of a feed hopper that controls the flow rate, volume, and timing of material release into downstream processes. It functions as an adjustable barrier to start, stop, or modulate the material stream.
Working Principle
Operates by moving a gate plate, slide, or rotating element to open or close the discharge opening. Manual, pneumatic, hydraulic, or electric actuators adjust the opening size to control material flow based on process requirements.
Common Materials
Stainless Steel, Carbon Steel, Aluminum
Technical Parameters
  • Diameter or width of the discharge opening (mm) Per Request
Components / BOM
  • Gate Plate Part
    Primary sealing and flow control element
    Material: Stainless Steel
  • Actuator
    Provides mechanical force to open/close the gate
    Material: Aluminum Alloy
  • Seal Part
    Prevents material leakage around the gate
    Material: Food-Grade Rubber
