Slide Valves

Reliable Solutions for Bulk Material Flow Control and Spillage Prevention

Slide valves are essential components used to regulate and interrupt the flow of free-flowing bulk materials in industrial processing systems. They provide effective shut-off and flow control for powders, granules, and dry materials in a wide range of applications.

These valves are widely installed at silo outlets, hoppers, weighing hoppers, screw conveyor inlets/outlets, and mechanical or pneumatic conveying systems.
They feature a low-profile design, reliable performance, and multiple actuation options suitable for diverse industrial requirements.

Industrial Applications

Slide valves are used in:

Silo outlets
Hopper feeding points
Weighing hopper discharge
Screw conveyor inlet and outlet sections
Mechanical conveying systems
Loading and unloading units
Food and chemical processing lines
Plastic, feed, cement, white cement, chemical and powder-processing plants

They are ideal for free-flowing materials, such as:
cement, carbonates, PVC, grains, sugar, dry sand, mineral powders, small pellets, and other similar bulk solids.

Design Features

Available in Three Geometric Configurations:

SVQ – Square section: 150 mm to 400 mm
SVC – Round section: 150 mm to 400 mm
SVR – Rectangular section: 200 mm and 300 mm

Low-profile construction

Allows easy installation under silos and hoppers with limited space.

Robust body materials

Available in three construction options:

Carbon Steel
Galvanized Steel
Stainless Steel (304/316) — ideal for food, chemical, and sanitary applications

High-strength blades

Blades are manufactured from the same material options to ensure maximum wear resistance.

EPDM sliding seal (Chute)

Provides flexible sealing and reduced friction during opening/closing.

Leak-proof design

Prevents material leakage and ensures a clean working environment.

Optimized for free-flowing materials

Ensures smooth operation with non-cohesive powders and granules.

Actuation Options

To meet different operational needs, slide valves are available with three actuation systems:

1. ACMS – Manual Actuation

Suitable for simple operations
Provides direct and easy manual control

2. ACPS – Pneumatic Actuation

Using pneumatic cylinders
Fast opening/closing
Ideal for automated systems

3. ACES – Electric Actuation

Suitable for heavy-duty applications
Smooth and precise control
Fully compatible with PLC and automation systems

Operational Advantages

Reliable design supporting continuous operation
High resistance to wear and corrosion
Low maintenance and easy access to components
Tight sealing to minimize material loss
Stable performance in demanding industrial conditions
Suitable for installation in confined spaces
Fully compatible with mechanical and pneumatic conveying systems

Why Slide Valves Are the Ideal Choice for Industrial Systems

Because they offer:

Excellent control of bulk material flow
High load-handling capability
Long service life
Stable and consistent performance
Food-grade compatibility (depending on material selection)
High technical value with low operational cost

Conclusion

Slide valves are highly reliable industrial components designed to control the flow of bulk solid materials in various processing environments.
With their multiple actuation options, diverse configurations, and durable construction materials, slide valves provide a safe, stable, and efficient solution for round-the-clock industrial operation.
