HDP Gate

Designed to handle higher-pressure applications up to 75 psig (5 barg), depending on size, the Vortex® HDP™ stands out from traditional industrial slide gates.

• Externally adjustable blade for in-line maintenance
• Patented “rising blade” action to provide a positive seal against high pressures
• Replaceable parts for in-line maintenance and extended service life
• End seal displacement pocket to prevent material from becoming trapped during closure
• Unobstructed opening to ensure unrestricted material flow and maintain convey line pressures
• An optional air purge assembly keeps fine materials in the flow stream to prevent them from accumulating in the gate body
• No pinch points or exposed moving parts for safety
• No internal cavities to prevent wedging, lodging, and spoilage
• Lifting lugs for easy installation

Gravity flow, dilute-phase, and dense-phase pneumatic conveying applications up to 75 psig | 5 barg | +0.5 MPa, depending on gate size. Can be used in pressure or vacuum systems.

Non-abrasive to moderately abrasive powders, pellets, and granules. Well-suited for handling sticky and/or corrosive materials, and for wash-down.

4–14 in | 100–350 mm ID and OD diameters are available. Also available in Schedule 10, 20, or 40 pipe sizes.

ANSI #125/150, DIN PN10 Custom flanges are available

250°F | 120°C for a standard gate, with modifications that allow temperatures up to 400°F | 205°C

304 or 316L stainless steel, carbon steel

Magnetic reed switches, proximity switches, or mechanical limit switches

Sealed-Body Air Purge Special Service Inlet

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

PET replaces nylon for the blade support guides.

Replace the ANSI-pattern inlet flange with a flange that matches the DIN mounting pattern. (Includes metric inserts.) Replace the lower flange on the outlet return pan to include laser-cut holes that match the DIN mounting pattern.

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

Add a welded integral Special Service Inlet to the standard Insert Flange and Insert Ring Assembly. (Must be oriented toward the closing end of the valve stroke) *Additional modifications available depending on the application
