Slide Gates
Slide Gates – Series 1905
SUDE Slide Gates are commonly used for On-Off Service applications, primarily serving as shut-off devices in material handling systems such as hopper shut-off valves. Beyond hoppers, they are suitable for a variety of industrial applications, including:
Crystallizer discharge gates in sugar industries
Dust extraction systems in steel and cement industries
Product Description:
A Slide Gate is a rugged and reliable mechanical flow control device used to isolate or regulate the flow of bulk materials in gravity-fed or pneumatic conveying systems. It features a flat or curved sliding plate that moves across the material flow path, enabling on/off or modulating control for materials such as powders, grains, ash, and granules.
Low Leakage Dual Blade Slide Gate Isolation Dampers:
These are specially designed for systems prone to material buildup around the blade seals. The dual blade design allows each blade to operate independently, enabling maintenance and cleaning of blade seals without taking the flue gas system out of service.

Working Principle:
Open Position
The gate is fully retracted, allowing unrestricted material flow through the passage.
Modulating Position
The gate is partially open, precisely controlling the material discharge rate.
Closed Position
The gate is fully shut, ensuring complete flow isolation for maintenance or process control.
Actuation Options:
Manual
Handwheel or lever-operated screw drive
Electric
Motorized actuator with feedback control
Pneumatic
Cylinder-operated with positioner
Hydraulic
High-torque actuation for heavy-duty gates
