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

Slide Gate Valves operate via a linear sliding blade that moves across the material flow path. When closed, the blade presses against sealing elements to ensure tight shut-off and minimize dust leakage. When open, the valve allows free passage of material. Depending on the configuration, the valve may be designed for unidirectional pressure, requiring correct installation orientation to ensure optimal sealing and reduced wear.

Benefits

• Reliable Shut-Off Performance even under heavy material loads

• Dust-Tight Sealing improving environmental safety and reducing product loss

• Robust Construction suitable for abrasive and coarse materials

• Flexible Design Options for various geometries and installation conditions

• Ease of Maintenance with accessible and adjustable sealing components

• Compact Design enabling integration in limited installation spaces

Available Options upon Request

• Heavy-duty execution for abrasive or coarse bulk materials

• Food-grade design with compliant materials and finishes

• ATEX-certified versions for explosive dust environments

• Custom sizes, shapes (round, square, rectangular) and flange configurations

• Integrated or external pneumatic and electric actuation systems

• Special sealing materials for high temperature or aggressive products

Technical Specifications

Description

Slide Gate Valves for Powders, Granules and Bulk Solids — carbon steel, stainless steel, or cast Body materials

Slide Gate Valves are used to isolate or regulate the flow of bulk materials in gravity-fed or conveying systems. Designed with durable materials and optimized sealing solutions, they ensure consistent operation even under high loads and abrasive conditions. Available in multiple sizes and configurations, they can be adapted to a wide range of installation requirements.

Function

The valves are installed at silo and hopper outlets, conveyor discharge points, or loading systems where reliable shut-off of material flow is required. They provide effective isolation with high dust-tightness, ensuring process safety and minimizing material loss.
