Valves for hygienic purposes

Alfa Laval ball valves are versatile full-bore valves that enable full fluid flow with zero flow restriction and minimal pressure drop. This enables easy transfer of viscous liquids or liquids containing particles through hygienic processing lines.

• Optimizes product recovery and complete cleanability of the valve bore and pipeline due to the full-bore, piggable design
• Minimized pressure losses, especially when handling high-viscosity liquids
• Zero flow restriction makes handling liquids containing large particles easy

Alfa Laval butterfly valves are relatively straightforward on/off routing valves and the ideal choice to optimize fluid handling in various applications.

Benefits:

• Excellent flow efficiency
• Reliable cost-effective performance
• Perfectly suited for food, beverage, home-personal care, biotech and pharmaceutical industries (UltraPure version)

Alfa Laval control/check valves manage the flow of process liquids and gases through hygienic process systems.

• Protect process systems against potential damage by eliminating vacuum conditions to equalize pressure in the system
• Ensure plant safety and protect upstream equipment by preventing reverse flow and water hammer
• Safely pressurize or release air from process pipelines and systems, preventing equipment damage whilst safeguarding product integrity and yield

Alfa Laval double seal valves are cost-effective mixproof valves that safely handle the simultaneous flow of two different products or fluids through the same valve without the risk of cross-contamination.

• Safely isolates two process fluids or a process fluid and cleaning media without the risk of contamination
• Increases both operational and product safety due to self-draining design
• Produces higher quality products at lower costs using aseptic double seal valves to secure your process

Alfa Laval diaphragm valves are aseptic inline valves to shut off, divert and/or regulate the fluid flow through hygienic, high-purity and aseptic processing lines.

• Ensure high-quality, contaminant-free products due to hermetic design and aseptic diaphragm technology
• Save time and money with compact, lightweight, easy-to-install valves from two-way to customized valve clusters
• Increase performance with purpose-built valves with minimal deadlegs and maximum drainability and cleanability

Alfa Laval regulating valves provide precision control of flow rate or pressure in hygienic processing lines. They are ideal for use in metering, blending, weighing, and filling system applications across the dairy, food, beverage, home-personal care, biotech, and pharmaceutical industries.

• Optimizes processes by monitoring and adjusting flow rate or pressure – quickly, safely and effectively
• Hygienic and aseptic designs that comply with international standards for hygienic processes
• Easy installation, reliable operation, and low maintenance

Alfa Laval safety valves maintain optimal operating conditions in hygienic applications due to overpressure, vacuum or unacceptable fluid levels. Minimizing the risk of explosion and implosion by relieving excess pressure or liquid levels from pipelines, vessels or equipment protects hygienic processing systems across the dairy, food and beverage, and brewery industries.

• Prevent injury to personnel and damage to pipelines, process vessels and equipment from vacuum conditions or unacceptable pressure and fluid levels
• Improve worker safety and protect against workplace accident or injury
• Minimize risk of damage due to explosion, implosion or collapse

Alfa Laval’s range of hygienic sampling valves are valves used to draw liquid samples for evaluation in hygienic and aseptic processes without contaminating the sample or the sample source.

• Representative, contamination-free sampling with various options and accessories, including a double seat valve cleaning functionality
• Safe sampling using quality sampling accessories, including pressure relief valves, to assure proper usage and workplace safety
• Sterile sampling using quality sampling accessories, including a steam generator or hypodermic needle, to ensure extraction of microbial-free samples

Alfa Laval shutter valves are hygienic three-way valves that divert the flow of products that are highly viscous, contain large particles, or have strict requirements on minimizing pressure loss. Compact, reliable and pressure-shock resistant, these valves can be operated in manual or automatic (pneumatic) mode.

Alfa Laval single seat valves (SSVs) are robust and reliable manual and pneumatic valves with a single plug design. Versatile and purpose-built, whether used for shutoff or changeover, these compact, modular valves are ideal for use wherever high standards of hygiene are required across the dairy, food, beverage, brewery, home-personal care and many other industries.

• Exceptional valve hygiene and durability
• Enhanced product safety due to superior cleanability with smooth, no-crevice inner valve body
• Reduced wear part maintenance requirements due to defined seal compression that extends seal life
