ODM – Flat slide gates SFD/SFL/SMU/SNA

Our Slide gates function as shut-off valves for all types of materials and are used under silos, bins, bunkers and dosing devices.

Slide gates are multi-functional and are in nearly all industry branches. They are put to use where materials must be transported in or out, or where they need to be dosed, or the flow rate must be limited.

When slide gates are used with pneumatic or mechanical conveyance, they are ideal in impeding the mass flow. Moreover slide gates can be used to relieve the load on subsequent hauling equipment such as conveyor screws, belt conveyors, or rotary valves.

Our slide gates are especially easy to integrate into existing systems due to their low overhead clearance, and they inspire confidence with their easy assembly.

DI MATTEO offers completely new units from scratch, a replacement of existing facilities, and spare parts for your existing equipment.
