When industrial processes involve extreme temperatures, abrasive media, or high pressures, soft-seated valves quickly degrade. The FlowBiz Brand Metal-Seated Butterfly Valve with a Spherical Disc is specifically engineered to bridge this gap. Featuring an advanced all-metal sealing architecture, this valve offers exceptional throttling and bi-directional shutoff capabilities where traditional resilient-seated valves fail.
Manufactured by FlowBiz Exports Pvt. Ltd., these valves feature a precision-machined spherical disc that reduces friction during operation, ensuring low torque, minimal wear, and an extended operational lifespan in the most punishing industrial environments.
The disc geometry is meticulously machined into a spherical profile.
The Benefit: This design allows the disc to cam smoothly into the metal seat, minimizing localized scuffing, reducing operational torque requirements, and drastically extending the lifecycle of the sealing surfaces.
Unlike elastomeric or PTFE seats that degrade under intense thermal stress, our all-metal seating configuration remains structurally sound.
The Benefit: Safe, reliable operation across an expansive temperature range from 50C up to 400C, making it ideal for superheated steam, thermal fluids, and hot gas lines.
Even with a robust metal-to-metal contact interface, precision engineering ensures an incredibly tight seal.
The Benefit: Compliant with ASME B16.104 Class VI leakage standards, guaranteeing a bubble-tight, high-integrity shutoff for critical isolation.
To combat varied chemical compositions and corrosive media, FlowBiz offers these valves in an array of high-grade cast and forged metals:
Carbon Steel (CS): Ideal for non-corrosive, high-strength utilities.
Stainless Steel (SS 304 / SS 316): Excellent for general corrosion resistance.
Low-Carbon Stainless Steel (SS 304L / SS 316L): Superior resistance to intergranular corrosion after welding.
