Safety valves

Alfa Laval safety valves maintain optimal operating conditions in hygienic applications due to overpressure, vacuum or unacceptable fluid levels. Minimizing the risk of explosion and implosion by relieving excess pressure or liquid levels from pipelines, vessels or equipment protects hygienic processing systems across the dairy, food and beverage, and brewery industries. This translates into higher levels of safety, less downtime and higher yields.

How does a safety valve work?

Alfa Laval safety valves to relieve pressure or prevent vacuum conditions are delivered with the counterweights or spring set and locked at pre-set opening pressures or opening vacuums to suit either customer requirements or the tank design data. When the pressure or vacuum in the tank exceeds the pre-set opening value, the valve relieves the excess pressure or lets in atmospheric air.
