Safety valve

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.

Reliable protection

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.
