Ventilate

Ball Valves

Alfa Laval’s ball valves are made for situations where the liquid just needs to pass freely, without narrow passages or unnecessary pressure drop. Their full-flow design makes them ideal for handling thicker liquids or products with particles. You get a reliable valve that does not clog and ensures a smooth flow even in demanding processes.

Butterfly Valves

Alfa Laval’s butterfly valves are reliable and hygienic on/off valves, widely used in stainless steel piping systems for the food, biotech, pharma, and personal care industries. 

With their simple design and large opening area, they offer low flow resistance and are ideal for applications where quick and frequent opening and closing of the flow is required. The valves are also available in versions that allow easy installation and intelligent process control.

• Low flow resistance and high throughput
• Suitable for liquids with low to medium viscosity
• High hygiene standard – CIP/SIP compatible
• Easy to install, service, and automate
• Available in UltraPure version for demanding applications

Control Valves

Alfa Laval’s control valves are designed to ensure stable and precise control of liquids and gases in hygienic process systems. They are widely used in various industries where reliable flow control is crucial for product safety and process quality. 

The range covers everything from check valves and vent valves to special valves for CO₂ control.

• Prevents backflow and protects product integrity
• Ensures efficient venting without product loss
• High operational reliability with low maintenance needs
• Optimized for precise pressure control and gas regulation

Diaphragm Valves

Alfa Laval’s diaphragm valves are developed for applications where sterility and precise fluid control are crucial. This is the case in high-purity and aseptic processes found in, among others, the food, dairy, biotechnology, and pharmaceutical industries. 

The valves are compact and flexible and are available in different configurations with valve bodies, diaphragms, and actuators that can be adapted to process needs.

• Hygienic and aseptic design for sterile processes
• Compact and lightweight construction – ideal for installation in tight spaces
• Modular design for easy adaptation and replacement
• Available with documentation packages for use in pharmaceutical environments
• Reliable sealing with reduced risk of contamination

Double Seal Valves

Alfa Laval’s double seal valves are designed to separate two different fluid streams in the same valve, without any risk of cross-contamination. They are an obvious choice in matrix piping systems and other installations where space and efficiency are in focus. 

The construction of the valves makes them a cost-effective alternative to more advanced mixproof solutions, without compromising on hygiene and operational reliability.

• Simultaneous handling of two fluids without cross-contamination
• Standardized and cost-effective solution
• Suitable for hygienic applications with high demands
• Easy to install and service

Regulating Valves

Alfa Laval’s regulating valves are developed to ensure precise control of liquid and gas flow in hygienic processes. They are used in everything from dosing and mixing to pressure regulation in tanks and pipelines and are designed to maintain high operational reliability, product quality, and process control.

• Precise and reliable flow and pressure control
• Suitable for demanding applications with high hygiene requirements
• Easy integration with existing process equipment
• Excellent cleaning properties and low maintenance
• Quick and easy setup with modern automation features

Double Seat Valves

Alfa Laval’s double seat valves – also known as mixproof valves – allow two different fluids to pass through the same valve without the risk of cross-contamination. The modular valves are designed for high flexibility and can be adapted to even the most demanding applications, both in standard and aseptic environments.

• Simultaneous handling of fluids without risk of cross-contamination
• Modular design – easy adaptation and upgrade
• High cleanability with effective CIP/SIP
• Lower total costs through extended lifespan and fewer downtimes
• Meets strict hygiene and documentation requirements (e.g., 3-A and FDA)

Safety Valves

Alfa Laval’s safety valves ensure the protection of your systems and products against dangerous pressure conditions in hygienic processes. They ensure that tank and piping systems are not damaged by overpressure, vacuum, or unwanted liquid levels, thereby contributing to safe operation and longer equipment lifespan.

• Prevents overpressure and vacuum in tanks and pipes
• Increases safety for both equipment and personnel
• Easy integration into SCANDI BREW® tank top systems
• Reliable performance even under demanding operating conditions
• Compact design and high operational reliability

Sampling Valves

Alfa Laval’s hygienic sampling valves are used to take liquid samples from tanks and piping systems in a safe and sterile manner. They allow for the collection of representative samples for quality control and analysis – without contaminating the product or the sample source. 

• Sterile sampling without risk of cross-contamination
• High accuracy and reproducibility
• Suitable for both bulk and micro samples
• Easy to operate and maintain
• Available in versions for both CIP and aseptic processes

Shut-off Valves

Alfa Laval’s shut-off valves are specially designed to handle products with high viscosity, large particles, or with requirements for minimal pressure resistance. These hygienic three-way valves enable reliable diversion of product streams where traditional valves often fall short. They are ideal for demanding applications where product protection and efficient flow are crucial.

• Efficient handling of viscous media and products with particles
• Low pressure drop that reduces load and energy consumption
• Flexible three-way function for optimal flow control

Single Seat Valves

Alfa Laval’s single seat valves (SSVs) are robust, versatile, and hygienic valves with a single plug design. They are available in both manual and pneumatic versions and are ideal for processes where there is a need for efficient shut-off, control, or switching of liquids and gases.

• Reliable and leak-free regulation with long lifespan
• Suitable for both simple and complex flow tasks
• Available in many configurations – for both standard and demanding applications
• Can be equipped with advanced automation and monitoring (e.g., ThinkTop)
