January 19, 2016 - Alfa Laval announces Safety Valves that protect against overpressure in tanks and pipelines caused by overfilling or fermentation processes.
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.
Features
- Dedicated and reliable protection against costly and devastating accidents
- Calibrated to the desired pressure set point, sealed and delivered with a PED certificate
- Hygienic design eliminates unsanitary leaks and overflow during and after pressure peaks
These safety valves protect 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.
