The gate adopts a double-acting cylinder, the pneumatic transmission is stable and reliable, and the opening and closing of the door are flexible. When working, the gate is driven by the piston rod of the cylinder to drive the shutter plate to reciprocate, and the stroke switch controls the piston rod movement of the cylinder. Such a gate plate is neither affected by the material card. Dead or missing material, is not to be taken out at the start. The gate plate moves freely and has low resistance. The installation distance can be met by two-stroke switches to meet the process requirements of feeding and unloading.

suitable for feed, flour, food, chemical, mining, metallurgy, cement, and other industries to control the flow of materials.
