Industry News

Sanitary diaphragm valves and sanitary globe valves are essential components in fluid control systems, particularly in industries with stringent hygiene requirements such as food, pharmaceuticals, and bioengineering. These valves ensure precise flow control, prevent contamination, and meet strict sanitary standards. With diverse production needs, both sanitary diaphragm valves and sanitary globe valves offer a wide range of options in terms of types, specifications, and materials, enabling users to select the ideal solution for their specific applications.

I.Understanding Sanitary Globe Valves 

While diaphragm valves are widely used for their sealing and contamination prevention capabilities, sanitary globe valves provide exceptional flow regulation and shut-off performance. These valves feature a spherical body and a movable disk that controls fluid flow, making them ideal for applications requiring precise flow adjustment. 

 Key Features of Sanitary Globe Valves:
Precise Flow Control: The linear motion of the disk allows for fine-tuned flow regulation, making them suitable for     dosing and metering applications.

Leak-Tight Shut-Off: The design ensures a tight seal, minimizing the risk of leakage.

Easy Maintenance: Their simple construction allows for easy disassembly and cleaning, crucial for sanitary applications.

Applications of Sanitary Globe Valves:

Pharmaceuticals: Used in processes requiring accurate dosing of active ingredients.

Food and Beverage: Ideal for controlling the flow of viscous liquids like syrups or dairy products.

Biotechnology: Ensures precise media flow in fermentation and bioreactor systems.

II.Structural Types: Tailored for Specific Applications

Both sanitary diaphragm valves and sanitary globe valves come in various configurations to meet specific operational needs.

Diaphragm Valve Types:

Straight-Through: Simple design with low flow resistance, suitable for most standard applications.

Angle: Enables 90-degree flow direction changes, saving installation space.

three-Way: Provides an additional cleaning position, ideal for CIP processes.

Globe Valve Types:

T-Pattern: Traditional design for general flow control.

Y-Pattern: Reduces pressure drop, suitable for high-pressure applications.

Angle Pattern: Combines flow regulation and directional change in one valve.

For example, a dairy production line might use straight-through diaphragm valves for material transfer and sanitary globe valves for precise control of cream flow during mixing, ensuring consistent product quality.

III.Specifications: Matching Scale and Efficiency 

The selection of valve specifications, whether for diaphragm valves or sanitary globe valves, directly impacts system performance. Sizes range from DN15 to DN200, catering to diverse needs from laboratory research to industrial production.

  Diaphragm Valves: DN15 valves are often used in R&D labs, while DN150 valves are suitable for large-scale fermentation tanks.

  Sanitary Globe Valves: DN20 valves are ideal for small-batch pharmaceutical dosing, while DN100 valves handle larger flow rates in beverage production.

IV.Material Selection: Ensuring Durability and Compliance 

Material choice is critical for both valve types, ensuring compatibility with media and compliance with industry standards.

Common Materials:

316L Stainless Steel: Offers excellent corrosion resistance and durability.

EPDM: Provides reliable sealing for general applications.

PTFE: Ideal for highly corrosive or high-purity media.

Specialized Applications:

Sanitary Globe Valves: Often use polished 316L stainless steel bodies and PTFE seals for high-purity applications like vaccine production.

Diaphragm Valves: Utilize EPDM or PTFE diaphragms for sterile processes in biopharmaceuticals.

VI.Application Considerations: Precision for Specific Needs

Choosing between diaphragm valves and sanitary globe valves depends on the specific requirements of the application:

  Diaphragm Valves: Best for applications requiring contamination prevention and easy cleaning, such as sterile processing or CIP systems.

  Sanitary Globe Valves: Ideal for applications requiring precise flow control, such as dosing, metering, or pressure regulation.
For instance, in a pharmaceutical plant, diaphragm valves might be used for sterile media transfer, while sanitary globe valves are employed for accurate dosing of active pharmaceutical ingredients (APIs).
