Technical Specification

Explore detailed product specifications and expand your technical knowledge of bulk handling valves for powders and granules used in gravity discharge, flow control, and isolation applications across industrial processes.

General Operation

The valve operates through a rotating disc mounted on a central shaft. In the closed position, the disc seals against the internal lining, ensuring dust-tight shut-off. In the open position, it allows full material flow. The simple mechanical design ensures reliable operation with minimal maintenance requirements.

Benefits

• Robust Construction suitable for heavy-duty and abrasive applications

• Reliable Dust-Tight Sealing reducing emissions and product loss

• Compact and Simple Design with few components for increased reliability

• Easy Installation and Maintenance in silo discharge systems

• Cost-Effective Solution for bulk material flow control

• Versatile Configuration Options for different installation geometries

Available Options upon Request

• Pneumatic or electric actuation systems

• Reinforced or abrasion-resistant internal linings

Technical Specifications

Description

Butterfly Valves Under Silo for Powders & Granules — Carbon Steel Body

Steel Butterfly Valves for under-silo installation are engineered for reliable shut-off and flow control of dry bulk materials such as powders and fine granules. Manufactured from robust carbon steel and equipped with wear-resistant components, these valves are specifically designed to operate in demanding environments such as building material processing plants and heavy-duty bulk handling systems.

Function

Installed directly beneath silos, hoppers, or bins, the valves provide effective interception or regulation of gravity-fed material flow. Their design ensures consistent sealing performance, minimizing dust emissions and preventing material leakage during operation.
