Manual Slide Gate Valve

Manual slide gate valves are mechanical valves designed to stop or regulate the flow of solid, granular, and powdered materials. Widely used in cement, mining, chemical, food, energy, plastic, and agricultural industries, these systems stand out for their high sealing performance, durability, and ease of use.

Commonly installed in silo outlets, feeding lines, and pneumatic conveying systems, manual slide gate valves allow operators to open and close the valve manually to control material flow. Due to their low cost, minimal maintenance requirements, and long service life, they are preferred by many industrial facilities.

How Do Manual Slide Gate Valves Work?

• Closed position: completely stops the material flow.
• Open position: allows free movement of granules or powders.
• Partial opening option: adjusts the flow rate to the desired level.

This system operates mechanically, providing reliable flow control without requiring electricity or air pressure.

Advantages of Manual Slide Gate Valves

• Cost-effective and economical solution: provides low-cost flow control without requiring electrical or pneumatic actuators.
• High durability: manufactured from wear-resistant materials, ensuring reliable operation in abrasive and high-temperature environments.
• Superior sealing performance: prevents leaks of dust and granular materials, ensuring a clean working environment.
• Easy installation and operation: can be easily integrated into silo outlets, feeding lines, and pipeline systems.
• Minimal maintenance requirements: fewer moving parts reduce wear and extend service life.
• Reliable manual operation: ensures safe and efficient flow control without relying on external power sources.
• Versatile connection options: available with flanged, clamped, or bolted mounting to suit various pipeline configurations.

Applications of Manual Slide Gate Valves

Manual slide gate valves are essential for controlling the flow of solid and powdered materials in various industrial processes:

• Cement and mining: regulates the movement of cement, gypsum, lime, coal, and minerals.
• Food and agriculture: controls the flow of flour, grains, sugar, coffee, starch, and animal feed.
• Chemical and plastic production: provides precise flow control for chemical powders, pigments, and plastic granules.
• Energy and biomass: used for solid fuel, biomass, and ash handling.
• Recycling and waste management: directs plastic, metal dust, and other recyclable materials efficiently.

Types of Manual Slide Gate Valves

• Flanged manual slide gate valve: compatible with standard pipeline systems.
• Wafer-type manual slide gate valve: compact and lightweight design, ideal for tight spaces.
• High-temperature manual slide gate valve: withstands up to 500°C, designed with special heat-resistant coatings.
• Abrasion-resistant manual slide gate valve: engineered for mining and cement industries, providing extra protection against abrasive materials.
• Hygienic manual slide gate valve: made of stainless steel, suitable for food and pharmaceutical applications.

Key Considerations When Choosing a Manual Slide Gate Valve

• Material type: choose a model suitable for powder, granule, or bulk material applications.
• Operating pressure and temperature: select a valve with sufficient durability for high-temperature or high-pressure environments.
• Connection type: ensure compatibility with silos, pipelines, or feeding systems.
• Material durability: opt for coated or reinforced models if handling abrasive chemicals or extreme temperatures.
• Sealing properties: high-quality seals should be chosen to prevent leaks of dust and materials.
