VL Slide Gate Valve Pneumatic Actuator Assembly

Filquip supplies the full range of WAM Slide Gate Valves for handling powder and granular materials. They are the perfect solution for isolating or intercepting material flow out of hoppers, silos and bins. Suitable for all industrial sectors and the food industry.

This video shows the assembly of a pneumatic actuator kit onto the VL Slide Gate valve. This is a VLQ series with Square inlet in the video.

Building Products Additive Powders Mobile Vacuum Loader

Filquip has recently supplied a mobile vacuum loader to a building products manufacturer in NSW to allow them to convey their additive powders into the inlet of the production line hopper.

Previously this customer had to bring a mobile platform ladder to each inlet hopper on the production line and use the ladder to get the height for the operator to pour the buckets of additive powders into the hopper.

With the Filquip FVC-1 now the operators move the mobile vacuum loader head over the hopper above and vacuum product with the wand up into the hopper without needing ladders or buckets of product at height.
