Hygienic Safety Valve Protects Against Pressure Buildup

The Alfa Laval Safety Valve, a true spring-loaded safety valve, is designed to protect both equipment and people. 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. The valve is calibrated to the desired pressure set point, sealed, and delivered with a certificate. A hygienic design eliminates unsanitary leaks and overflow during and after pressure peaks.  

The safety valve complements the Alfa Laval Scandi Brew range, of hygienic, anti-vacuum and overpressure valves. These safety valves protect against overpressure in tanks and pipelines caused by overfilling or fermentation processes. They also protect against implosion due 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 into a combined safety valve, protecting against both vacuum and overpressure in one hygienic valve solution with a single tank connection.
