For difficult applications or those involving sticky, abrasive, or corrosive materials, the patented Vortex® HDP® Slide Gate valve offers reliable service life for positive material shutoff.

The HDP® Slide Gate, designed specifically to handle dry bulk solids in pneumatic or gravity conveying systems. The HDP® can be applied to control material flow in gravity, dilute phase, or dense phase conveying systems up to 75 psig (5 bar), depending on size and modifications. It is available in 100 to 400mm (6 to 16 inches).

In difficult applications, the HDP® has proven to be reliable and exceeded the service life of the valves it replaced. Whether it’s cement, sand, or cullet, the HDP®’s patented rising blade seals high pressure without abrading the seal, which compensates for wear over extended use and reduces the need for frequent maintenance. The HDP® is also able to handle high-temperature applications, up to 450° F (232°C).

Adapting the HDP® Slide Gate to system requirements is made easy with air, electric, or hydraulic actuators, position indication switches, and ANSI #125/150 or DIN flanges. The HDP® also offers a wide variety of modifications to accommodate a range of temperatures, corrosive, humid, and hazardous environments.

Additional options include 304 Stainless Steel, 316L Stainless Steel, or a combination of Carbon Steel and 304 Stainless Steel material contact; built-in material shear protector to minimize material contact with the seal upon blade closure, thus maintaining seal integrity; and optional pre-wired terminal box, NEMA 4, NEMA 7/9, or ATEX-rated single or double solenoids, and proximity or magnetic reed position indication switches.
