Regulating Valves

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. They also ensure safe and effective operation, easy maintenance, high product quality and enhanced productivity.

Let Alfa Laval regulating valves control your hygienic and aseptic processing lines by maintaining precision control of flow rate or pressure. Designed to meet process demands for hygiene and safety, these valves monitor and adjust process parameters to boost performance whilst ensuring product quality and safety as well as process integrity.

How Do Regulating Valves Work?

Regulating valves are controlled either manually on site or from a remote location in one of the following ways:

• Adjusting a regulator on the backside of the diaphragm to set the air pressure to a fixed pressure set point
• Using pneumatic actuators controlled by a positioner
• Using a digital electropneumatic process controller

The Alfa Laval SB Pressure Exhaust Valve is a pneumatic regulating valve that automatically releases pressure in a hygienic process tank when it exceeds the set pressure. To ensure safe pressure regulations at all times, the set pressure can easily be adjusted manually or from a remote location that is connected to the central control system.

This pneumatic regulating valve is designed for use in process tanks or vessels for hygienic applications in the brewery, food, dairy, beverage and many other industries.

Safe, effective pressure regulation

Easily integrated into a central process control system, this pneumatic valve ensures safe, reliable and hygienic performance by releasing pressure in the process tank when it exceeds the set point pressure. The set point pressure can be adjusted manually or remotely.

Hygienic, easy-to-clean design

Smooth surfaces and food-grade finishes ensure superior hygiene. For fast, effective cleaning, a cleaning nozzle is supplied for inline cleaning during CIP of the vent/recovery mains. Alternatively, an optional CIP supply valve can connect directly to the valve housing.

Flexible valve mounting

The valve can be positioned on the tank top, as part of a tank top system, or elsewhere in the pipework with proper drainage from the housing.

The Alfa Laval SB Tank Pressure Regulator maintains the working pressure in the vapour space, or at the top, of a process tank during filling, processing and emptying. It generally connects directly to the gas pipe or Cleaning-in-Place (CIP) pipe that leads in to the tank top, or is incorporated into a flow panel. This ensures process safety and effectiveness as well as safeguards product integrity.

This control valve typically regulates the pressure in tanks used in the dairy, food, beverage, brewery and many other industries. The valve easily integrates with an Alfa Laval SCANDI BREW® tank top system.

Secure tank top pressure control

Maintaining the working pressure at the tank top is critical. The tank pressure regulator makes sure that the pressure in the vapour space of a process tank is always at the optimal setting. This ensures the safety and effectiveness of your processes and safeguards product integrity.

Modular hygienic design

All pressure regulator components are made of high-quality hygienic materials that meet stringent food and beverage processing standards. Modular design provides the flexibility to meet most installation requirements. Hygiene is assured through the use of a CIP adaptor to provide full cleanability.
