（EN）A Complete Guide for Selecting Industrial Flow Control Gates in Powder & Bulk Conveying Systems
（ID）Panduan Lengkap Memilih Flow Control Gate untuk Sistem Penanganan Material Curah
Introduction — Why Flow Control Gates Matter
Flow Control Gates play a critical role in bulk material handling, ensuring accurate feeding, flow regulation, and safe discharge of powders such as cement, clinker, lime, fly ash, gypsum, grain, and minerals.
Selecting the wrong gate can lead to:
- Material leakage
- Unstable flow
- System blockage
- Higher maintenance
- Reduced operational efficiency
This guide will help you choose the correct Flow Control Gate for your plant and application.
Types of Flow Control Gates (Which One Do You Need?)
Motorized Flow Control Gate
Best for high-precision regulation, especially in cement plants and automated bulk material lines.
✔ Fine control
✔ Adjustable opening
✔ Good for continuous production
🔗 Motorized Flow Control Gate – LVRUI
Pneumatic Flow Control Gate
Ideal for fast switching, high-frequency operations, and systems requiring immediate response.
✔ Quick action
✔ Lower cost
✔ Simple automation
✔ Good for fly ash, grain, powders
🔗 Pneumatic Flow Control Gate – LVRUI
Manual Flow Control Gate
Best for low-frequency regulation or systems without automation.
✔ Low cost
✔ Simple maintenance
✔ Suitable for non-critical flow control
Key Factors When Selecting a Flow Control Gate
Material Type & Characteristics
Different materials have different flow behaviors.
Consider:
- Powder fineness
- Moisture content
- Abrasiveness
- Temperature
Highly abrasive materials (clinker, minerals) require wear-resistant liners.

Required Flow Accuracy
Choose motorized gates for precise feeding control.
Choose pneumatic gates for bulk open/close operations.
Actuation Method
| Actuator Type | Advantages | Applications |
|---|---|---|
| Motorized | Precise flow control | Cement plants, batching systems |
| Pneumatic | Fast response | Fly ash, powder conveying |
| Hydraulic | High force | Heavy-duty or sticky material |
| Manual | Basic control | Low-use systems |
Sealing System（Zero Leakage Is Critical）
Key criteria：
- Dust-tight sealing
- Anti-wear design
- Proper gasket material
- Smooth contact surfaces
🔗 Butterfly Damper Valve – Dust Control
Installation Space & Mounting Position
Check：
- Silo outlet size
- Conveyor connection flanges
- Vertical vs horizontal installation
- Actuator clearance
Safety & Dust Control Requirements
Flow Control Gates must comply with industrial safety guidelines.
