FlowBiz: High-Performance PFA/FEP Lined Butterfly Valves
Premium Lined Butterfly Valve Manufacturer in India
FlowBiz Export Private Limited is a premier manufacturer of high-quality PTFE-lined butterfly valves, engineered to provide superior fluid control in highly corrosive and ultra-pure environments. Our valves feature a robust metallic body and a precision-moulded thermoplastic lining that acts as an impenetrable shield against aggressive chemicals, acids, and high-temperature media.
As a leading PTFE-lined butterfly valve manufacturer in India, FlowBiz combines advanced metallurgy with premium lining materials (PTFE, FEP, and PFA) to ensure a 100% leak-proof seal and zero contamination. Whether you are operating in the heavy industrial belts of Gujarat or the high-tech clusters of Maharashtra, our valves are built for long-term structural integrity and operational precision.
Technical Specifications
We offer a versatile range of configurations tailored to meet global industrial standards:
- Size Range: 50mm to 300mm (2 inches to 12 inches)
- Pressure Rating: PN10 / PN16
- Body Materials (MOC): Cast Iron, SG Iron (Ductile Iron), SS304, and SS316.
- Lining Options: FEP(Fluorinated Ethylene Propylene) and PFA(Perfluoroalkoxy).
- End Connection: Wafer Type (Designed to suit ASA 150 Class & DIN standards).
- Operation: Manual (Lever/Gear), Pneumatic, or Electric Actuation.
Key Features & Operational Benefits
- Total Corrosion Resistance: The full lining protects the body and stem from corrosive fluids.
- Bubble-Tight Shut-Off: The resilient seat design ensures a gas-tight seal even at low-pressure differentials.
- Low Friction Torque: The smooth surface of the PTFE/PFA liner reduces friction, resulting in easy operation and extended actuator life.
- Zero Contamination: Ideal for pharmaceutical and food-grade applications where the purity of the media is critical.
- Compact Wafer Design: Lightweight and space-saving, allowing for easy installation and maintenance between flanges.
Technical Comparison: Choosing the Right Lining
In the world of high-performance fluoropolymers, selecting the right lining is crucial for valve longevity. Here is the technical breakdown:
Feature | PTFE | FEP | PFA |
Full Name | Polytetrafluoroethylene | Fluorinated Ethylene Propylene | Perfluoroalkoxy |
Temperature Range | Up to 260°C | Up to 204°C | Up to 260°C |
Chemical Resistance | Excellent (Standard) | Good | Outstanding (Premium) |
Mechanical Strength | Moderate | Moderate | High (Resists deformation) |
Flex Life (Durability) | Good | Moderate | Superior (Best for high cycles) |
Clarity/Purity | Opaque | Transparent | High Purity (Ultra-smooth) |
Best Use Case | General Chemical Service | Moderately corrosive / Low temp | Severe service / High vacuum |
Why the Lining Choice Matters?
1. PTFE (The Reliable Standard)
PTFE is the "go-to" for most industrial chemical applications. It has a very low friction coefficient, meaning your valves open and close smoothly. However, because it cannot be melted and moulded (non-melt-processible), it is usually fitted as a separate liner.
2. FEP (The Cost-Effective Choice)
FEP is an excellent option for applications that don't reach extreme temperatures. It is highly resistant to chemicals and is more transparent than PTFE, but it has a lower melting point, making it unsuitable for very hot processes.
3. PFA (The Premium Performance)
PFA is the "Gold Standard" for FlowBiz valves. Because it is melt-processible, it can be precision-moulded directly to the valve body, creating a tighter bond. It offers the same heat resistance as PTFE but with much better mechanical toughness and resistance to "creep" (stretching under pressure).
