Slide gates
Sliding-blade gate valves that control, isolate and shut off the discharge of bulk materials from silos, hoppers and conveying systems.
Slide gates are used to control, isolate and regulate the discharge of bulk materials from silos, hoppers or conveying systems. They are a key component in handling powders, granules and grains, ensuring controlled material flow and reliable shut-off within industrial processes.
Engineered to handle challenging materials, slide gates are available in configurations suited for abrasive, fine or cohesive products. Design features such as reinforced seals, wear-resistant components and optimized blade guides help reduce material buildup and ensure consistent performance over time.
When correctly specified, slide gates improve process stability, enable safe equipment isolation and contribute to reliable operation across the entire bulk material handling system.
How Slide Gate Valves Work
The equipment consists of a sliding blade moving within a rigid frame, designed to create a tight seal against material leakage. The flat blade slides within a rigid frame to control, isolate or shut off the flow of dry bulk materials — powders, granules and grains — from silos, hoppers and conveying systems.
Types & Actuation
Depending on the application, gates can be operated manually / Hand-Operated Slide Gates or automated via pneumatic (pneumatic slide gate valves) or electric actuators (electric / motorised slide gate valves), allowing integration into process control systems. These valves are also frequently used in ATEX environments.
Designs & Options
Slide gates include orifice and rounded-blade designs, heavy-duty options for abrasive materials, and sanitary Quick Clean Gates for frequent clean-out. These valves are also frequently used in ATEX environments.
Applications
Silo & hopper discharge, conveyor & transfer points. gravity flow and dilute- or dense-phase pneumatic conveying.

Frequently Asked Questions
What is a slide gate valve?
A slide gate valve is a linear-motion valve with a flat blade that slides in a rigid frame to control, isolate or shut off the discharge of dry bulk materials such as powders, granules and grains from silos, hoppers and conveyors.
What is the difference between a slide gate and a knife gate?
A slide gate uses a flat plate to shut off the flow of dry bulk solids, while a knife gate has a sharpened (beveled) blade designed to cut through thick liquids, slurries and pulp. For powders, pellets and grains, a slide gate is the correct choice.
How is a slide gate valve actuated?
Slide gates can be operated manually (hand wheel/lever), pneumatically (single or double-acting cylinders) or electrically (motorised actuators), with intermediate positions available for metering. ROCOM specifies the actuation to match the process and control system.
Can slide gates handle abrasive or cohesive materials?
Yes. For abrasive, fine or cohesive products, slide gates use reinforced seals, wear-resistant components and optimised blade guides to reduce build-up and maintain a tight shut-off over time; ATEX-rated executions are available for explosive dust zones.
Where are slide gate valves installed?
They are typically installed under silos and hoppers, at conveyor discharge and transfer points, and as isolation or emergency shut-off valves — anywhere controlled material flow and reliable shut-off are required.
