Junteng Sanitary Aseptic Stainless Steel 316 Manual Tri-Clamp Silicone Sealing Diaphragm Valve

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. How It Works?

• Sealing Mechanism: When the valve is closed, a compressor pushes the flexible diaphragm down against a central ridge or seat in the valve body.

• Isolation: The diaphragm completely separates the fluid from the valve's stem and actuator. This eliminates the need for traditional stem packing seals, which can trap bacteria and cause leaks. 

• Flow Control: Lifting the actuator allows the diaphragm's natural elasticity to flex upward, providing an unobstructed path for fluid with very low pressure drop. 

3. Key Design Features:

• Materials: Product-wetted parts are constructed from high-purity, corrosion-resistant stainless steel (typically 316L). The diaphragm itself is usually made of food/pharmaceutical-grade elastomers like EPDM, Silicone, or PTFE. 

• No Dead Legs: They are designed to prevent "dead legs" or crevices where product can pool, which is critical to stopping bacteria and mold growth. 

• Cleanability: The smooth internal surfaces are engineered to be easily sterilized and cleaned using Clean-in-Place (CIP) and Steam-in-Place (SIP) methods. 

4. Technical Specification:

     3A 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!

• Materials: Typically constructed with a 316L stainless steel body and a dual-layer diaphragm (such as PTFE and EPDM) to handle high purity standards.

• Operation: Valves can be manually operated or controlled pneumatically.

• Connections: Available with various sanitary connections including tri-clamp, butt-weld, or threaded ends. 

5. Key Applications and Use Cases:

• Pharmaceutical & Biopharma: Essential for sterile processing lines, WFI (water for injection) systems, and aseptic fluid transfer where zero contamination is required. 

• Food, Dairy & Beverage: Used in processing lines for milk, wine, and brewing where daily clean-in-place (CIP) and sterilize-in-place (SIP) processes are necessary.

• Semiconductor & Electronics: Utilized for ultrapure water (UPW) systems and corrosive chemical delivery lines to prevent particulate buildup and maintain ultra-clean standards. 

• Chemical Processing: Deployed to handle highly corrosive acids, bases, and abrasive slurries without damaging the valve's working parts.
