Made from durable metals and hard polymers, it ensures a dust-tight or positive seal with deflectors and retainers that protect seals from material flow, reducing wear and extending lifespan. Its self-cleaning mechanism prevents metal-on-metal contact, eliminating galling and contamination while improving durability. Replaceable parts like bonnet seals and cam-adjustable rollers can be serviced without removing the gate, offering convenience and easy maintenance.
Compatible with gravity-fed hoppers, silos, mixers, screw conveyors, etc. it handles non-abrasive powders to moderately abrasive granules and can be customized for sticky or corrosive materials. Wash-down modifications and compliance with FDA and ATEX regulations broaden its versatility. Standard sizes range from 6 to 30 inches, with custom options available, and drive mechanisms include air cylinders, hand wheels, chain wheels, or electric actuators. Position confirmation is available via magnetic reed, proximity, or limit switches, with optional clear bonnet covers for monitoring.
Features like the Special Service Inlet, sealed body air purge, and live-loaded, wear-compensating polymer seals ensure long-term performance with minimal maintenance. Setting the standard for precision, reliability, and efficiency, the Vortex Roller Gate avoids common slide gate issues like leakage, wedging, and seal wear.
