Description
Note: This diaphragm valve cannot be used for drinking water.
The key component of the PVC diaphragm valve is a flexible diaphragm that separates the valve’s body from the flow path. This diaphragm is made of CPVC or UPVC which can withstand corrosive or acidic substances.

Tips: Flanged diaphragm valve advantages
Flanged diaphragm valves offer several advantages in various industrial applications. Their design features a flexible diaphragm that acts as a barrier between the process fluid and the valve components, providing numerous benefits:
- Exceptional Sealing: Diaphragms ensure a tight and reliable seal, preventing leakage and cross-contamination. This is particularly important in industries where purity and sterility are critical, such as pharmaceuticals or food production.
- Corrosion Resistance: Diaphragm valves can be made from materials that are highly resistant to corrosion, making them suitable for handling aggressive chemicals and corrosive fluids.
- Minimal Maintenance: Their simple construction minimizes the need for maintenance, resulting in reduced downtime and cost savings.
- Precise Flow Control: Diaphragm valves offer excellent throttling capabilities, allowing for precise control over flow rates, making them ideal for applications requiring accurate dosing or control.
- Biocompatibility: In the medical and biotech industries, these valves are suitable for handling sensitive or biocompatible fluids due to their diaphragm materials.
- Reduced Fouling: The smooth, obstruction-free flow path minimizes the risk of fouling and clogging, ensuring consistent performance.
- Versatility: Flanged connections make installation and integration into existing systems straightforward.
