The Alfa Laval Safety Valve protects your equipment, your environment, and the health and safety of your workers. This safety device is designed to open and relieve excess pressure from vessels or equipment and then reclose and prevent the further release of fluid when the system returns to normal.
Relieve excess pressure
Pressure can build inside vessels or systems due to blocked discharge, thermal expansion, chemical reactions, or a combination of these events. The Alfa Laval Safety Valve is designed to flexibly relieve excess pressure from vessels or equipment at all times and under any circumstances. As the last and vital component in accident prevention, a high-quality, hygienic safety valve is an essential part of your operations.
Get the perfect fit
Depending on the causes of excess pressure, a different mass or volume flow may need to be discharged. With this type of variable flow, a perfectly fitted safety valve is essential. The Alfa Laval Safety Valve comes in sizes from DN25 to DN100 with a spring-loaded set pressure range between 0.2 and 12.0 bar depending on the size of the valve.
In a potentially dangerous situation, the Alfa Laval Safety Valve is designed to open at a predetermined set pressure. The compressed spring force, which keeps the valve closed below the set pressure, 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.
- Dedicated protection. The Alfa Laval Safety Valve delivers reliable protection against costly and devastating accidents.
- PED approved. Calibrated to the desired pressure set point, sealed and delivered with a corresponding PED certificate.
- Hygienic design. Designed to eliminate unsanitary leaks and overflow during and after a pressure spike.
How it works
The Alfa Laval Safety Valve comes in sizes from DN25 to DN100 with spring loaded set pressure range from 0.2 to 12.0 bar. The valve can be pneumatic or manually operated. The Alfa Laval Safety Valve is calibrated to the desired pressure set point, sealed and delivered with a corresponding PED certificate.
The closing force in the Alfa Laval Safety Valve is applied by a compressed spring with a set pressure greater than the operating pressure.
In a potentially dangerous situation, the valve will open at the predetermined set pressure. The spring force acts in the closing direction and the force created by the pressure at the inlet of the safety valve acts in the opening direction. At a certain point, these forces will be balanced out and the valve will make an initial discharge to relieve the pressure.
