Slide valves for flow interception in powder and granular materials

Effectively manage the flow of powdery and granular materials with high resistance to abrasion and seamless integration into your existing systems, ensuring optimal sealing and operational safety.

Intercepts and Controls Material Flow

The VL Slide Valve from WAMGROUP is uniquely designed for efficient material flow control in various industrial applications. Utilizing a robust two-piece frame, partly coated with WAM’s SINT engineering polymer, these valves minimize abrasion and eliminate the need for flange gaskets. They intercept granular and powdery materials in processes such as flour milling, cement production, and wastewater treatment. Available in manual, pneumatic, and electric operations, the valves integrate seamlessly into production lines, featuring compact dimensions, particularly the VLS version, which includes a pneumatic actuator. Constructed from either carbon or stainless steel, with options for food-grade polymers, the valves ensure safe operation with an all-around dustproof seal. Compliant with industry standards and available in various geometries, the VL Slide Valve is versatile for horizontal or vertical installations, engineered to reduce maintenance with easily dismantled components.

Benefits

  • Increases material handling efficiency with precise flow control.
  • Enhances durability with abrasion-resistant SINT polymer components.
  • Reduces maintenance time due to easy disassembly and reassembly.
  • Ensures safe operation with fully sealed, dustproof design.
  • Adapts to diverse industry applications with customizable configurations.
