MANUAL TYPE SLIDE GATE VALVE

A manual type Slide Gate Valve is a robust and reliable mechanical device designed to regulate or completely shut off the flow of dry bulk materials such as powders, granules, pellets, and even certain types of coarse solids within a material handling system. These valves are widely used in industries that handle bulk solids—including cement, chemicals, food processing, agriculture, and power generation—due to their simplicity, durability, and effectiveness

At the core of the valve is a sliding gate or blade, which moves horizontally across the valve opening. This gate acts as a barrier that can be positioned fully open, fully closed, or anywhere in between, allowing precise control over the amount of material passing through. The gate is housed within a rigid frame and typically operates between two seats that help seal the flow path when the valve is closed.

The manual operation of the slide gate is achieved through mechanisms such as a handwheel, lever, or gear assembly, depending on the size and application. These allow the operator to easily adjust the position of the gate without the need for electrical or pneumatic power, making it ideal for locations where utilities may not be readily available or where simple, low-maintenance solutions are preferred.

Constructed from materials like mild steel, stainless steel (SS304, SS316), or other wear-resistant alloys, these valves are built to withstand the abrasive nature of many bulk solids. Some designs incorporate sealing elements such as PTFE, rubber, or metal-to-metal contact to provide a dust-tight seal and prevent material leakage during shut-off.

Manual slide gate valves are often installed below hoppers, bins, silos, or at discharge points of conveyors or mixers to control material flow during processing, packaging, or maintenance operations. Their straightforward design and ease of operation make them a cost-effective and practical solution for bulk material handling applications.

Key Features:

• Manual Operation: No need for electrical or pneumatic actuation—simple hand-operated mechanism
• Slide Plate Mechanism: A flat or curved gate slides across the valve opening to allow, restrict, or stop material flow.
• Rugged Construction: Typically made of mild steel, stainless steel, or other wear-resistant alloys to handle abrasive or corrosive materials.
• Mounting Flange: Easily installed between flanges of hoppers, silos, screw conveyors, or ducts.
• Low Maintenance: Few moving parts mean simpler maintenance and lower operating costs.
• Low Maintenance: Few moving parts mean simpler maintenance and lower operating costs.
