Protecting employees, equipment and the environment

In a potentially dangerous situation it will open at a predetermined set pressure. The compressed spring force, keeping the valve closed, is forced open when pressure builds up at the inlet of the safety valve. As these forces balance out, the valve will discharge and decrease pressure, ultimately reclosing as the system returns to normal.

It provides dedicated protection against costly and devastating accidents and is calibrated to the desired pressure set point, sealed and delivered with a PED certificate. Its hygienic design eliminates unsanitary leaks and overflow during and after pressure peaks.

The company recently introduced a range of Alfa Laval Scandi Brew anti vacuum and overpressure valves:

• Alfa Laval SB Pressure Relief Valve
• Alfa Laval SB Anti Vacuum Valve
• Alfa Laval SB Anti Vacuum House

These safety valves are said to protect against overpressure in tanks and pipelines caused, for example, by overfilling or fermentation processes. They also protect against implosion due, for example, to vacuum caused by cold rinsing after hot cleaning or blocking of gas supply during emptying.

The Alfa Laval Safety Valve can be combined with the Alfa Laval SB Anti Vacuum House to protect against both vacuum and overpressure in one hygienic valve solution with a single tank connection.
