 Key Features of WH Sanitary Stainless Steel Pneumatic Fluorine Lined Diaphragm Valve  

 1. Sanitary Design for Hygienic Applications  

The WH sanitary diaphragm valve is designed to meet 3-A, ASME BPE, and FDA standards, ensuring compliance with strict hygiene requirements. Its smooth, crevice-free surface prevents bacterial growth and facilitates easy cleaning (CIP/SIP).  

 2. High-Quality Stainless Steel Construction  

Made from 316L or 304 stainless steel, this valve offers excellent corrosion resistance and durability, making it suitable for aggressive media and high-purity applications.  

 3. Fluorine-Lined Diaphragm for Chemical Resistance  

The PTFE (Teflon) or PFA-lined diaphragm provides exceptional resistance to acids, alkalis, solvents, and corrosive chemicals, ensuring long service life even in harsh environments.  

 4. Pneumatic Actuation for Automated Control  

Equipped with a pneumatic actuator, this valve allows for remote and automated operation, improving efficiency in industrial processes. The actuator can be configured for single-acting (spring return) or double-acting operation.  

 5. Bubble-Tight Sealing & Zero Leakage  

The diaphragm sealing mechanism ensures zero leakage, preventing cross-contamination and ensuring process integrity. This makes it ideal for sterile and ultra-clean applications.  

 6. Easy Maintenance & Long Service Life  

The modular design allows for quick disassembly and maintenance without requiring special tools. The wear-resistant diaphragm extends valve lifespan, reducing downtime and replacement costs.  

 7. Multiple Connection Types Available  

The valve supports various sanitary connections, including:  

- Tri-clamp (DIN 32676, SMS, ISO 2853)  

- Butt weld (ASME BPE)  

- Flanged (DIN, ANSI, JIS)
