Introduction
Sanitary butterfly valves are essential components in industries where hygiene and contamination control are prioritized, such as pharmaceuticals, food processing, and biotechnology. The performance and durability of these valves greatly depend on the materials used in their liners. This article provides an in-depth analysis of the materials used in liners for sanitary butterfly valves, with a specific focus on the solutions offered by Sansheng Fluorine Plastics.
Materials Used in Sanitary Butterfly Valve Liners
The liners in sanitary butterfly valves play a crucial role in sealing and isolating the flow of fluids. The materials commonly used include:
- PTFE (Polytetrafluoroethylene): Known for its non-reactivity, low friction, and high-temperature resistance, PTFE is ideal for handling aggressive chemicals and high purity applications.
- EPDM (Ethylene Propylene Diene Monomer): This synthetic rubber is often used for its excellent resistance to heat, ozone, and weather conditions. It is suitable for use with water and steam.
- Silicone: Silicone liners are preferred for their flexibility, biocompatibility, and stability across a wide temperature range, making them ideal for pharmaceutical applications.
- FPM/FKM (Fluoroelastomer): These materials offer high resistance to chemicals and heat, making them suitable for demanding industrial applications.
Comparison of Materials
The selection of liner material depends on the specific application and conditions. Below is a detailed comparison based on key parameters:
| Material | Temperature Resistance (°C) | Chemical Resistance | Durability | Applications |
|---|---|---|---|---|
| PTFE | -200 to 260 | Excellent | High | Chemical, pharmaceutical |
| EPDM | -50 to 150 | Good | Moderate | Water, steam |
| Silicone | -60 to 230 | Good | Moderate | Food, pharmaceutical |
| FPM/FKM | -20 to 204 | Excellent | High | Industrial, chemical |
