The Vortex Hand Slide Orifice 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. The gate seat and live-loaded seals are protected from material flow by a metal insert. By design, the valve “self cleans” material from the seat on each stroke of the valve blade improving overall seat life.

Material/ Metal contact is 316L stainless steel.
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 are made allowing 400 F (204 C) continuous to 450 F (232 C) intermittent service.
Gate blade is electropolished. Polyethylene (PET or UHMW) pressure plate seals are used to replace nylon.
