(Katup Pengatur Aliran Manual | Katup Aliran Material Curah)
High-Efficiency Manual Flow Gate for Silos, Hoppers, Chutes & Industrial Conveying Lines
Overview
The Manual Flow Control Gate Valve is designed to regulate, adjust, and shut off the flow of dry bulk materials—such as cement, fly ash, clinker, lime powder, grain, and other powders.
Manual flow control gate valve is widely used in cement plants, fly ash terminals and powder conveying lines.

Features
✅ Manual flow control gate valve
✅ Cement silo discharge valve
✅ Powder material flow regulation
✅ Adjustable sliding gate valve
✅ Manual shut-off valve for bulk solids
✅ Gate valve for cement, fly ash & powder conveying
✅ Suitable for silo, hopper, air slide, and bulk loading system
Working Principle
The manual gate valve operates through a sliding plate driven by a handwheel or lever.
By adjusting the opening width, the operator can precisely control the material flow rate, ensuring smooth discharge without clogging.
The valve regulates material flow through a manual sliding plate.
This design helps prevent clogging and ensures stable discharge according to industrial safety standards ›OSHA Bulk Material Handling Guidelines.

FAQs About Manual Flow Control Gate Valve
What is a manual flow control gate valve used for?
A manual flow control gate valve is used to regulate, start, stop, or adjust the discharge of dry bulk materials such as cement, fly ash, clinker, lime powder, and other powders. It is commonly installed under silos, hoppers, bins, or conveyor inlets for stable material flow control.
What is the difference between a manual flow control gate valve and a slide gate valve?
A manual flow control gate valve is designed for adjustable flow regulation using a handwheel or lever, allowing operators to control material flow rate. A slide gate valve is typically used for full open or full close isolation. Flow control gates offer more precise discharge adjustment than standard slide gates.
Can manual flow control gate valves handle abrasive bulk materials?
Yes. Manual flow control gate valves can be designed with wear-resistant liners, reinforced sliding plates, and heavy-duty frames, making them suitable for abrasive materials such as cement clinker, fly ash, and mineral powders.
Where are manual flow control gate valves commonly installed?
These valves are commonly installed at silo outlets, hopper discharge points, chute bottoms, air slide inlets, and bulk material transfer points where controlled and stable material flow is required.
Can manual flow control gate valves be integrated into a bulk material handling system?
Yes. Manual flow control gate valves are key components in complete bulk material handling systems, working together with conveyors, feeders, air slide conveyors, loading chutes, and dust collection equipment to ensure safe, efficient, and dust-controlled material transfer.
