Description
Double Flanged Damper Valve - Heavy-Duty Flow & Draft Control
FlowBiz Exports is a premier manufacturer and exporter of industrial-grade Double Flanged Damper Valves, engineered for high-volume air, gas, and flue gas handling. Built with dual flanged end connections, these damper valves provide superior structural strength, vibration resistance, and secure pipeline integration for heavy-duty industrial ducting networks.
Key Features & Operational Superiority
- Rigid Double Flange Construction: Ensures sturdy bolt-up alignment between duct flanges, providing stability in high-vibration and high-velocity gas environments.
- Minimal Pressure Drop: Full-bore disc design allows maximum air/gas flow efficiency with minimal pressure drop across duct systems.
- Thermal Expansion Accommodation: Specially engineered disc clearances and shaft bearings prevent binding during extreme thermal fluctuations.
- Flexible Actuation: Can be equipped with manual hand levers, worm gearboxes, pneumatic cylinders, or electric rotary actuators for automated control.
