The ZG type screw gate is needed to cover the outlet openings of the bunker, load conveyors or other technological equipment. It can be used for more accurate dosing of the product, for sealing containers from moisture (cement, flour, etc.), for hot or specific products. The actuator can be manual or electric.

The gate frame is made of structural, galvanized or stainless steel with a thickness of 3 mm and a gate with a thickness of 3 mm or more.

For trouble-free long-term operation, a screw made of steel 45 and a bronze nut made in Italy are used, and limit or inductive sensors are used to control the position of the gate.
