Alfa Laval LKB UltraPure Sanitary Butterfly Valve, Hygienic Flow Control

The Alfa Laval LKB UltraPure sanitary butterfly valve, also referred to as the LKB UltraPure Klappenventil, is engineered for reliable on off flow control in high purity, aseptic and sterile hygienic processing applications. Built on the proven LKB valve platform, it delivers dependable shut off performance and controlled flow for low to medium viscosity fluids.

This Alfa Laval butterfly valve is widely used in biotechnology, pharmaceutical manufacturing, food and beverage and personal care production, where cleanability, product integrity and validation documentation are critical. The valve is available in manual and automated configurations, making it suitable for both simple hygienic utilities and fully controlled process lines.

For regulated industries, the LKB UltraPure supports qualification and validation through Alfa Laval Q-doc documentation, including material traceability and documentation transparency. This helps reduce qualification effort while maintaining hygienic standards in modern sterile and aseptic plants.

ISO 2037, Sterile, Aseptic Systems Compatibility

Available with ISO 2037, DIN and ASME BPE end connections, the LKB UltraPure integrates into ISO 2037 sterile and ISO 2037 aseptic hygienic process lines used in biotech and pharmaceutical plants. It provides reliable on off flow control as part of validated hygienic piping systems.

Features and Benefits

Hygienic Design for High Purity Applications

• Maintains safe and controlled on off flow control for low to medium viscosity fluids
• Minimizes contamination risk with surface finishes down to Ra less than 0.4 um, or electropolished options, depending on specification
• Supports hygienic installation practices aligned with ASME BPE, DIN 11850 and ISO 2037 connection standards, depending on selected end connections

Dependable Performance

• Optimised stem and disc geometry helps reduce flow resistance
• Advanced seal technology supports chemical resistance and thermal stability
• Available as manual, or pneumatically actuated butterfly valve configurations

Cost Effective, Easy Maintenance

• Economical alternative to diaphragm valves in hygienic systems where butterfly valve shut off is suitable
• Only one wear part typically requires replacement during service
• Quick inline installation supports reduced downtime

Documentation Transparency, Alfa Laval Q-doc

• Material certificates and traceability
• Manufacturing and quality documentation
• Equipment manuals and service instructions

Supports GDP and validation requirements in regulated industries.

Unique Control, ThinkTop and Actuation Options

For automated hygienic lines, the LKB UltraPure butterfly valve can be paired with Alfa Laval valve sensing and control units such as ThinkTop, helping align with searches like Alfa Laval Unique Control and automation related LKB Klappenventil configurations. Manual versions use quarter turn handles with locking options, while automated versions use pneumatic actuators to rotate the disc 90 degrees.

The LKB UltraPure butterfly valve is available in manual and pneumatically actuated versions.

Manual operation uses a quarter turn handle with multiple locking and regulating options.

Automatic operation uses a pneumatic actuator rotating the disc 90 degrees, available in NC, NO, or Air Air configurations. The valve integrates with Alfa Laval ThinkTop valve sensing and control units to support indication and control in hygienic processing environments.
