Description
MS Fabricated Butterfly Valve - Heavy Duty & Custom Flow Control
FlowBiz Exports is a leading manufacturer and exporter of heavy-duty MS Fabricated Butterfly Valves (Mild Steel Fabricated). Custom-engineered for large diameter pipelines, water supply mains, HVAC, and industrial air/gas ducting, these fabricated valves provide high structural integrity, lightweight installation, and tailored face-to-face dimensions to meet exact site requirements.
Key Features & Operational Superiority
- Custom Fabrication Flexibility: Built from structural carbon/mild steel plates, allowing fully customizable face-to-face dimensions, flange drilling, and disc profiles.
- Cost-Effective Large Diameter Solution: Provides a robust and economical alternative to heavy cast iron or cast steel valves in large pipeline diameters.
- High Flow Efficiency: Streamlined disc geometry minimizes pressure drop and turbulence in high-volume fluid and air conveyance systems.
- Corrosion Protection Coating: Finished with high-build epoxy, polyurethane, or anti-corrosive industrial coatings for superior longevity against ambient weather and fluid exposure.
