Premium Stainless Steel Valve Sanitary Pneumatic Diaphragm, DN15 to DN65

1. Brief Introduction of Products:

A sanitary diaphragm valve is a highly specialized valve used in hygienic and aseptic applications. Its defining feature is a flexible membrane (diaphragm) that isolates the internal fluid from the mechanical operating parts, preventing contamination.

2. Key Functions:

•Diverting (Splitting): Directs a single flow from one inlet port into two different outlet ports.

•Mixing: Combines two separate flows coming into the valve into one combined outlet stream.

•Switching: Alternates flow paths between the ports depending on system requirements.

3. How It Works?

• Actuation: Compressed air enters the valve’s actuator, pushing the internal diaphragm down to seal the valve shut (or lifting it to open). 

• Isolation: The flexible diaphragm acts as a barrier, completely separating the fluid in the pipeline from the mechanical actuator components. 

• Fail-Safe Options: These valves are available in normally closed (NC) or normally open (NO) configurations, meaning they will default to a safe, closed, or open state if the air supply is interrupted.

4. Technical Specification:

     DIN/SMS/3A/ISO Standards

This product are also available in DIN, ISO/IDF, SMS, BSP standards. Please feel free to contact us if you need it in other standards!

5. Key Applications and Use Cases:

Because of their leak-tight and highly hygienic design, these valves are an industry standard in: 

• Pharmaceuticals and Biotech: Used in sterile process lines and aseptic environments.

• Food and Beverage: Utilized in systems requiring frequent washdowns and sanitary conditions.

• Semiconductor Manufacturing: Employed in ultra-high-purity gas distribution.

• Water Treatment: this flexing action opens and closes specific ports, seamlessly routing or isolating the media.
