Description
Wafer Type Damper Valve - Low Pressure & High-Temperature Flow Control
FlowBiz Exports is a leading manufacturer and exporter of heavy-duty Wafer Type Damper Valves designed for low-pressure gas, air, and flue-gas ducting systems. Engineered for rapid isolation, air balancing, and temperature regulation, these valves offer a compact, lightweight structure that easily fits between pipe flanges in space-constrained industrial pipelines.
Key Features & Operational Superiority
- Compact Wafer Design: Ultra-thin face-to-face body structure minimizes pipe space requirements and overall installation weight.
- Low Pressure Drop: Streamlined disc profile reduces turbulence and air resistance, ensuring high flow efficiency in large-volume gas ducting.
- High-Temperature Resistance: Fabricated with heat-resistant steel and specialized disc trims capable of handling extreme hot gases and thermal expansion.
- Custom Actuation Options: Available with manual lever, gear operator, pneumatic cylinder, or motorized electric actuator for seamless automated control.
