The Vortex\u00ae Maintenance Gate is designed to shut off material from a hopper or silo when maintenance of downstream equipment is required.<\/p>\n
\u2022 PTFE-treated bonnet packing gland, for greater wear resistance and longer service life
\n\u2022 Non-rising stem, for easier manual actuation
\n\u2022 Hand crank actuation, as a standard
\n\u2022 Designed to close through a standing column of material in the case of an upset condition
\n\u2022 Optional Special Service Inlet to protect the seals from abrasion
\n\u2022 Bonnet cover constructed from clear polycarbonate, for operator safety and to protect the gate from its environment
\n\u2022 Constructed from specialized metals and polymers for application-specific durability
\n\u2022 No internal cavities to prevent wedging, lodging, and spoilage
\n\u2022 Narrow profile for limited space applications<\/p>\n
