Detailed Description

Multi-Port Diaphragm Valve – Compact, Hygienic Solution for Complex Flow Control

The multi-port diaphragm valve is an advanced hygienic valve solution engineered to optimize space, reduce dead legs, and simplify piping layouts in high-purity process systems. It is particularly well-suited for pharmaceutical, biotechnological, and food-grade applications where cleanliness, efficiency, and process reliability are critical.

Key Features and Advantages:

◆ Compact and Space-Saving Design

Combines multiple flow paths within a single valve body, minimizing the need for complex pipework and reducing the system’s overall footprint.

◆ Hygienic Construction

Manufactured from high-grade stainless steel (typically SS316L) with smooth internal surfaces, electropolished finishes, and fully drainable designs to meet stringent sanitary requirements such as ASME BPE, EHEDG, and 3-A.

◆ Multiple Configurations

Available in T-, L-, U-, and custom porting designs to accommodate various process requirements such as sampling, distribution, diversion, mixing, or tank switching.

◆ Reduced Dead Volume

Optimized internal geometry significantly reduces dead space and the risk of contamination, supporting effective CIP/SIP processes.

◆ Flexible Operation

Available in manual, pneumatic, or electric actuation. Can be equipped with smart control heads, position sensors, and feedback systems for integration into automated process lines.

◆ Process Efficiency

By consolidating multiple functions into a single valve block, this design reduces the number of welds, lowers the risk of leakage, and simplifies validation and maintenance procedures.

◆ Diaphragm Technology

Utilizes proven diaphragm sealing technology to isolate the product contact area from external mechanical components, ensuring high sealing integrity and sterile operation.

Typical Applications:

Media distribution and collection systems

Bioreactor feed and harvest lines

CIP/SIP routing

Aseptic processing and fill-finish lines
