Description
Metal Seat Butterfly Valve - High-Temperature & Severe Service Flow Control
FlowBiz Exports is a leading manufacturer and exporter of heavy-duty Metal Seat Butterfly Valves, specially engineered for high-temperature, high-pressure, and abrasive slurry applications where soft seats fail. Built with precision-machined metal-to-metal seating surfaces, these valves provide long-lasting durability, exceptional fire-safe protection, and reliable tight shut-off in extreme industrial environments.
Key Features & Operational Superiority
- Extreme Temperature Endurance: Rugged metal-to-metal seating operates seamlessly at elevated temperatures without seat deformation or degradation.
- Abrasive & Slurry Resistance: Stellite-hardfaced or stainless steel seating withstands erosive fluids, fly ash, and solid-laden media without scoring.
- Fire-Safe Structural Integrity: Inherently fire-safe design ensures complete operational safety during emergency high-heat exposure.
- Bi-Directional Sealing: Advanced seal geometry delivers reliable tight shut-off across high differential pressures in both flow directions.
