VL-type Slide Valves consist of a two piece carbon or stainless steel frame, which is partly coated with WAM® unique SINT® engineering polymer composite, and a sliding blade manufactured either in the same material or in carbon or stainless steel. The use of SINT® engineering polymer composites considerably increases resistance to abrasion compared to traditional valves. In the VLQ version the valves have square, in the VLC version a circular opening. The VLS version with square opening has pneumatic actuator integrated in the frame.

VL Slides Valves are used where flow of a bulk solid caused by gravity or transport has to be intercepted. Valves may be fitted to hopper or silo outlets, to the inlets and outlets of mechanical conveyors and to the inlet of telescopic loading spouts. For the outlets of conveyors in particular, the VLS version with integrated pneumatic actuator is a valid option due to ist compact overall dimensions. The special geometry of the VL Slide Gate Valves and the different options of blade design enable their application in virtually every sector including the food industry.
