Slide Valves VL

The increased use of WAM’s special SINT engineering polymer in designing the VL range makes these Slides Valves the ideal equipment for intercepting the flow of powdery or granular materials in gravity or conveying applications.

Technical Features


VL-type Slide Valves consist of a two-piece carbon or stainless steel frame partly coated with WAM’s SINT engineering polymer composite, as well as a sliding blade manufactured from SINT engineering polymer, carbon steel or stainless steel. The use of the unique SINT engineering polymer composites considerably increases resistance to abrasion as compared to traditional valves. Moreover, it avoids the use of flange gaskets.
VL Slide Valves are available in a variety of configurations including rectangular sizes. In the VLQ version the valves come with a square, in the VLC version with a circular open cross section, whereas in the VLR-version it is rectangular. The VLS version with square cross section has a pneumatic actuator integrated in its frame.

  • Easy to handle
  • Highly abrasion-resistant
  • Easy and quick to fit
  • Safe sealing with no additional measures due to the all-round dustproof seal lips integrated into the polymer coating
  • Valve frames entirely coated with SINT engineering polymer composite (food-grade, FDA/EN-approved on request)
  • Absence of pinch points and exposed moving parts ensures safe operation
  • Horizontal or vertical mounting
  • Efficient sealing against fine powders and dust
  • Integrated service inlet to deflect material away from seals and rollers, thus reducing wear
  • Interchangeable actuators: manual, pneumatic, electric gear motor
  • ATEX-certification
  • Available in different materials
  • Ex-stock delivery
