Advantages
• Small installation height required, ideal for space-constrained applications.
• The screw is not exposed, making it less prone to rust, impact damage, and debris entanglement.
• More durable in dusty and muddy environments, less likely to jam the screw.
• Simple structure, cheaper than through-type valves.
• Safe operation, preventing injury to personnel and equipment.
Applicable Media & Scenarios
• Sewage, sludge, mud, ash, dust, coal dust slurry
• Papermaking, wastewater treatment, mining, dust removal flues, slurry pipelines
• Confined spaces, underground pipe corridors, outdoor open-air environments, and high-dust environments
