Welcome to FlowBiz Export Private Limited, a certified global manufacturing authority for heavy structural fluid control, large-bore distribution manifolds, and custom-fabricated quarter-turn isolation networks. Operating state-of-the-art sheet-rolling complexes, advanced multi-axis CNC machining centers, and heavy hydrostatic test bays in Gandhinagar and Ahmedabad, Gujarat, we stand as India's premier manufacturer, supplier, and global B2B exporter of industrial Mild Steel (MS) Fabricated Butterfly Valves.
Our high-capacity fabricated butterfly assets are engineered to provide maximum structural integrity and reliable throttling across high-pressure environments, bulk liquid lines, and facility utility pipelines. From our advanced corporate production headquarters in Gujarat, we seamlessly support major infrastructure projects across India's key industrial corridorsincluding Ahmedabad, Vapi, Valsad, Surat, Gandhinagar, Kutch, Ankleshwar, Bharuch, Mumbai, Nashik, Pune, Thane, Aurangabad, Satara, Sangli, Nagpur, Kolhapur, Indore, Dewas, Bhopal, Chennai, Coimbatore, and Salembacked by fast-tracked global logistics for direct international project export.
FlowBiz MS Fabricated Butterfly Valves utilize a specialized heavy-wall structural design where a precision-machined circular disc rotates on a high-tensile drive shaft. To eliminate the structural casting defects, gas porosity, and weight penalties common in traditional cast valves, our valve shells and inner discs are custom-welded from structurally verified premium steel plates.

Standard cast valves can harbor hidden micro-voids that structural pressure spikes or water hammer can turn into catastrophic casing cracks. Our butterfly valves are specifically designed and fabricated to perform in high-pressure conditions. By combining structurally rolled mild steel plates with robust ductile iron elements, the valve casing provides superior mechanical strength, excellent ductility, and structural longevity under severe pipeline stresses.
Whether your piping infrastructure is managing thin industrial air networks, volatile gas systems, or high-velocity fluid lines, our fabricated disc profile is engineered to optimize system efficiency. The thin, aerodynamic design of the internal disc allows it to slice through dense fluids with minimum resistance, reducing pressure drops and localized turbulence. This design makes the valve highly suitable for both quick, reliable shut-off and continuous flow modulation.
To ensure a long service life in harsh industrial plants, the valve shell features an advanced round, silver-finished protective coating. Beyond giving the valve a clean aesthetic, this industrial surface treatment provides exceptional resistance to atmospheric oxidation, chemical splashing, and severe weathering. This finish shields the underlying metal matrix and lowers regular external plant maintenance needs.
Equipped with an ergonomic manual hand lever or an enclosed heavy-duty worm gearbox, our valves offer efficient manual control for hands-on operation. This independent manual setup functions reliably without needing external electrical grids or compressed air drops. The compact profile fits cleanly between matching pipeline flanges, ensuring a secure fit, easy maintenance, and minimized downtime during installation.
FlowBiz high-performance MS fabricated butterfly valves are specified across primary processing lines:
Bulk Industrial Fluid Distribution: Sectional isolation within water treatment plants, manufacturing facilities, cooling tower loops, and raw intake headers.
Factory Process Air & Gas Networks: High-capacity compressed air distribution mains, non-corrosive gas pipelines, and industrial ventilation exhaust lines.
Chemical Facility Process Utilities: Low-to-medium pressure chemical transport, utility waste streams, and facility neutralization circuits.
Municipal Infrastructure Pipelines: Municipal water transmission lines, storm water pumping stations, and sewage filtration manifolds.
A: Standard cast iron valves are brittle and can fracture under heavy pipeline vibrations or thermal expansion cycles. Our fabricated valves leverage the superior strength of high-grade ductile iron and structural mild steel plates. This material matrix gives the valve body higher structural flexibility, allowing it to deform slightly under extreme pressure surges rather than crack. This design ensures long-term operational integrity where safety and structural durability are critical.
A: Proper mechanical alignment is essential to prevent flange distortion and premature seat wear. Technicians must align the valve's circular body cleanly between the matching pipeline flanges, ensuring that the piping is straight and parallel. Insert high-quality, pressure-rated gaskets between the sealing faces, then push standard structural bolts through the holes. Tighten these bolts progressively using a torque wrench in an alternating cross-star pattern to distribute clamping force evenly, achieving a secure, leak-proof mechanical joint.
A: Yes. While our standard valves are equipped with manual hand levers or gearboxes for efficient manual control, the topworks feature an industry-standard mounting pad. If your facility transitions to automated control loops or requires remote emergency isolation, your maintenance team can unbolt the manual handle and mount a pneumatic diaphragm cylinder, hydraulic piston, or an electric multi-turn actuator directly onto the existing shaft without removing the valve from the pipeline.
A: The process begins with selecting premium, structurally verified ductile iron and mild steel plates, followed by precise multi-axis CNC fabrication to your required size dimensions. After precision assembly with high-resiliency elastomeric seats, each individual valve undergoes stringent quality checks and thorough pressure testing according to API 598 standards. This process ensures bubble-tight seating and structural performance before the assets are cleared for international dispatch.
