HDP Gate

Designed to address higher-pressure applications up to 75 psig (5 barg) depending on size, the Vortex® HDP™ sets itself apart from traditional industry slide gates.

• Externally adjustable blade for in-line maintenance
• Patented “rising blade” action to positively seal against high pressures
• Replaceable parts for in-line maintenance and prolonged service life
• End seal displacement pocket to prevent material packing upon closure
• Unobstructed opening for unrestricted material flow and to maintain convey line pressures
• Optional air purge assembly keeps fine materials in the flow stream, to prevent them from collecting in the gate’s body
• No pinch points or exposed moving point for safety
• No internal cavities to prevent wedging, lodging & spoilage
• Lifting lugs for ease of installation
