The Lorenz discharge valve is manufactured with heavy-duty 3/16-in. stainless blades with built in material scrapers that aid in minimizing material packing or building up. The square machined blade “dead ends” against the body of the valve allowing material to escape below. The valve seals top to bottom to a maximum of 15 PSI. Typically the valve is installed between a bin or hopper and a rotary airlock. Product flow from the bin above can be controlled without shutting off the rotary airlock. The valve will vent air only (not product) from the perforated steel on the bottom of the valve. As an option the valve can be air purged to prevent any venting of air. It can cut through a standing column of material without using a special service inlet. Lorenz Conveying Products Corp., Cobourg, ON, Canada 800-263-7782 www.lorenz.caLorenz Conveying Products Corp.
