QUANTUM-SERIE
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.
PTFE-treated bonnet packing gland, for greater wear resistance and longer service life
Non-rising stem, for easier manual actuation
Hand crank actuation, as a standard
Designed to close through a standing column of material in the case of an upset condition
Optional Special Service Inlet to protect the seals from abrasion
Bonnet cover constructed from clear polycarbonate, for operator safety and to protect the gate from its environment
Hergestellt aus speziellen Metallen und Polymeren für anwendungsspezifische Langlebigkeit
Keine inneren Hohlräume, um ein Verklemmen, Festsetzen und Verderben zu verhindern
Schlankes Profil für Anwendungen mit begrenztem Platzangebot

Vortex Maintenance Gate vs. Alternatives
The design and construction of the Vortex® Maintenance Gate offers significant advantages over traditional carbon steel maintenance gates.
• The Maintenance Gate’s aluminum body and frame make it lightweight and corrosion-resistant. The gate’s stainless steel material contact areas provide additional resistance to corrosion and wear. This provides the Vortex Maintenance Gate with long-term and reliable service.
• Many alternative maintenance gates allow metal-on-metal sliding, which creates galling. This causes a gate to seize and bind, and can create foreign metal fragment contamination. The Maintenance Gate's hard polymer liners eliminate metal-on-metal contact to resolve each of these concerns.
• Many alternative maintenance gates rely on soft rubber seals which are directly exposed to the material flow stream. These seals rapidly erode or tear away in service. This deficiency promotes leakage of materials and dusts past the gate and to atmosphere, in addition to actuation issues and several other maintenance concerns. The Maintenance Gate addresses these issues by incorporating a bonnet seal cartridge, which houses a PTFE-treated packing gland. PTFE-treated packing gland provides greater wear resistance and longer service life than alternative sealing materials. Within the bonnet seal cartridge, the packing gland expands to create a dust-tight seal around the vertical perimeter of the blade. The bonnet seal cartridge shields the packing gland from the material flow stream, to protect it from abrasion. This design maintains the gate’s positive seal with infrequent maintenance intervention. Once the packing gland has experienced significant frictional wear, it can be removed and replaced to restore the gate’s dust-tight seal. This maintenance process can be performed while the gate remains in-line.
• The Maintenance Gate’s stainless steel blade and hard polymer liners are FDA-compliant. This makes it an excellent choice in food handling applications and other applications where carbon steel and aluminum are not acceptable for material contact.
