A new automatic opening and closing type valve exclusively for powder and granular materials has arrived.
A valve specifically designed for powder and granular materials that can automatically open and close using pneumatic pressure. ○ This is a shutter-type valve equipped with an air cylinder that can automatically open and close using pneumatic pressure. ○ It is effective in processes such as filling powder and granules, as well as in the input of raw materials. ○ The exterior components are made entirely of stainless steel, and the structure is designed to prevent water from entering the cylinder interior through a scraper provided at the movable part of the cylinder. ○ It can be safely used even in food manufacturing processes where there is a possibility of water droplets coming into contact. ○ The upper part has a Heller connection, making it easy to detach. ○ The lower part has a short pipe with protrusions, making it difficult to disconnect when connecting to a chute or similar.

Applications/Examples of results
The shutter valve opens and closes automatically with an air cylinder. This leads to labor-saving in the opening and closing process and reduces the contamination risk associated with manual handling. The opening and closing speed varies depending on the air supply amount and the tightening torque of the butterfly screw on the shutter valve body. It can close instantly or relatively slowly.
