How To Choose The Right Material For Sanitary Diaphragm Valve?

When choosing the material of Sanitary Diaphragm Valve, you need to consider multiple factors, including corrosion resistance, high temperature resistance, wear resistance, and compliance with specific hygiene standards. ‌

Corrosion resistance‌:

The diaphragm material of the diaphragm valve is usually made of synthetic materials such as polytetrafluoroethylene (PTFE) and polypropylene (PP), which can resist corrosion from most chemical media and ensure long-term stability and safety. ‌
High temperature resistance‌:

For sanitary applications that require aseptic conditions, the choice of materials is crucial. 316 stainless steel is a corrosion-resistant material that can maintain stability in high temperature environments, which is very suitable for such applications. ‌
Wear resistance‌:

Considering that sanitary diaphragm valves need to be cleaned frequently, the wear resistance of the material is equally important. 316 stainless steel is very suitable for such occasions that require frequent cleaning due to its excellent wear resistance. ‌
Sanitary standards‌:

Sanitary diaphragm valves must comply with international food, pharmaceutical and biological product industry hygiene standards, such as FDA certification, EHEDG certification, etc. These certifications ensure the safety and reliability of the valve in the applicable environment. ‌
Other considerations:

Installation and removal: For easy installation and removal, the clamp disc design is a good choice, which makes the operation easier and less labor-intensive.

Scope of application: Sanitary diaphragm valves are suitable for corrosive, viscous and abrasive fluids, as well as sanitary applications that require aseptic conditions. Its wide range of applications makes it an ideal choice for many application scenarios.

In summary, choosing the right material is crucial to ensuring the performance and applicability of sanitary diaphragm valves. Users should carefully select the most suitable material combination based on specific application requirements and environmental conditions to achieve safe and efficient operation.
