Description
Double Flanged Butterfly Valve - High Performance Flow Control Solution
FlowBiz Exports is a trusted manufacturer and global supplier of high-quality Double Flanged Butterfly Valves engineered for demanding industrial operations. Designed with flanged end connections on both sides, these valves provide exceptional structural stability, tight shut-off, and low torque operation in large-diameter pipelines.
Key Features & Engineering Excellence
- Rigid Body Structure: Double flanged body design ensures easy installation, rigid piping support, and safe dead-end service capabilities.
- Bi-Directional Sealing: Provides zero-leakage tight shut-off in both flow directions, reducing operational downtime.
- Low Operating Torque: Optimized disc and stem alignment reduces actuator load and lowers energy consumption during operation.
- Replaceable & Integral Seat Options: Available in soft seats (EPDM, NBR, PTFE) for resilient sealing and metal-to-metal seating for high-temperature/high-pressure services.
