Maintenance Slide Gates
Meyer Maintenance Slide Gates are essential components designed to effectively isolate sections of a system, ensuring easy removal, service, and emergency shut-off. These gates are specifically engineered to provide a reliable and cost-effective solution for controlling material flow in gravity batch unloading systems.
Positioned between rotary valves below and hoppers above, Meyer Maintenance Slide Gates offer a secure, positive shut-off, allowing for the service or replacement of rotary valves without the need to empty the hopper, ensuring minimal disruption to operations.
Manually operated with a low-profile design, the Maintenance Slide Gate is fully dust-tight from the inside out, making it an ideal choice for dry bulk handling, gravity, and pneumatic conveying systems. These gates are available in sizes to match standard square or round flange patterns of Meyer Airlock Feeders, with custom sizes available to meet specific requirements.
