Alfa Laval safety valves
Applying the Alfa Laval Safety Valve
The Alfa Laval Safety Valve is a spring loaded valve which is used to prevent over pressure in tanks and vessels in the dairy, food and beverage, and biopharm industries. Furthermore it helps to reliably avoid damages to people and equipment.
Working principle
Safety Valves are used to prevent inadmissible over pressures of fluids in tanks, containers and plant sections. In the factory the valve is configured with a set pressure upon request that is greater than the operating pressure. The valve opens against a spring force if the operating pressure increases the set pressure. Preferably, the Alfa Laval Safety Valve should be installed vertically. If mounted horizontal the set pressure will be a bit lower than specified due to the missing weight of the piston. Highest effect on DN80 and DN100.
Standard Design
The Alfa Laval Safety Valves are available in sizes from DN25 to DN100 with spring loaded set pressure range from 0.2 to 12 bar. A valve can be pneumatic or manually operated and are delivered with PED certificate.
