Alis Valves is a leading manufacturer of Manual Enclosed Slide Gate Valves designed for efficient isolation of bulk materials such as powders, granules, and ash. Operated manually using a handwheel or lever, these valves feature a fully enclosed construction that prevents dust leakage and ensures clean operation. Built for durability and smooth performance, they are ideal for cement plants, power plants, mining, and bulk handling industries.

Product Specifications and Overview

ALIS Valves offers Manual Enclosed Slide Gate Valves for industrial applications requiring reliable isolation and controlled discharge of dry bulk materials. These valves feature an enclosed housing with a sliding gate that moves across the material flow path to open or close the passage. The gate is operated manually using a handwheel, lever or suitable mechanical arrangement, depending on the valve design. The enclosed construction helps contain dust and minimize material leakage into the surrounding environment, making these valves suitable for applications where clean operation and dependable material control are important.

Manual Enclosed Slide Gate Valves are suitable for applications in cement plants, power generation facilities, food processing industries, chemical plants, mining operations and bulk material handling systems. They are commonly installed beneath silos, hoppers, storage bins, conveyors and dust collection equipment to control the discharge of powders, granules and other dry materials. Important selection factors include material characteristics, particle size, bulk density, operating temperature, valve dimensions, sealing arrangement, body material and manual operating requirements. Selecting the appropriate valve configuration helps support efficient material flow, effective dust containment and reliable operation under the intended working conditions.

Frequently Ask Questions

A Manual Enclosed Slide Gate Valve is a manually operated industrial valve designed to isolate and shut off the flow of dry powders, granules and bulk materials. The sliding gate remains enclosed within the valve body during operation.
The enclosed construction protects the moving gate from direct exposure to the surrounding bulk material and helps reduce dust accumulation around the operating mechanism.
Alis Valves is a Manual Enclosed Slide Gate Valve manufacturer and supplier in India, offering manual slide-gate solutions for cement, fly ash, mining, power, chemical, fertilizer, silo, hopper and dry bulk-material handling applications.
The operator rotates the handwheel or operates the manual mechanism to move the slide linearly across the material passage. When fully closed, the gate isolates the downstream equipment or material flow.
They are commonly installed in: Cement plants Silo outlets Hopper outlets Fly ash systems Mining plants Power plants Powder-processing systems Bulk-material handling systems
