The Vortex® Maintenance Gate is designed to shut off material from a hopper or silo when maintenance of downstream equipment is required. In the open position, it positively seals conveying air and material to atmosphere. The hand crank gearing is designed to close through material in case of an upset condition.
Ideal application: Shut off material flow when maintenance of downstream equipment is required or if an upset condition occurs.
