Handslide Gate

The Vortex® Handslide Gate™ is designed specifically to handle dry bulk solids in gravity flow conveying. A full flow orifice provides unrestricted conveying of material with no disk or ledges to impede flow or cause material bridging.

• Displacement area as an alternative to packing materials into an end seal
• Live loaded, wear compensating hard polymer pressure plate seals
• Shimming system for in-line maintenance
• Optional locking pin to secure the blade in the open or closed position
• “Scissoring” action reduces seal wear and minimizes material shearing
• Stainless steel liners protect the gate’s seals from material flow
• Mechanically self-cleans its seals on the opening stroke, if actuated to full-open
• No internal cavities to prevent wedging, lodging, and spoilage
• Flange options to match up with equipment above and below the gate

Non-abrasive to moderately abrasive powders, pellets, and granules. Modifications are available for handling corrosive materials and/or for wash-down.

2 – 14 in | 50 mm – 355 mm ID & OD diameters are available. Also available in schedule 10, 20 or 40 pipe sizes.

ANSI & Standard stud bolt pattern Modified pipe flanges available

180° F | 80° C for a standard gate, with modifications that allow for temperatures up to 400° F | 205° C

Nylon, PET, UHMW-PE, 25% glass-filled PTFE, molybdenum disulphide-impregnated nylon

Natural rubber and/or silicone rubber

ATEX Zone 20 (internal), ATEX Zone 21 (external), FDA

Mounting studs are removed and special mounting holes matching an ANSI pattern are provided for bolting through the gate flange. Not all holes are able to be used.

Modifications are made allowing 250 F (121 C) continuous to 300 F (149 C) intermittent service.

Modifications have been made to allow for continuous operation at 400 F (204 C) and intermittent operation at 450 F (232 C).

The gate blade is electropolished. Polyethylene (PET or UHMW) pressure plate seals are used in place of nylon. *Additional modifications are available depending on the application.
