Safety valves can be employed as relief or overflow valves in the refrigerant cycles of industrial refrigeration systems.
Safeguarding refrigeration systems, including it’s component parts, from excess pressure requires the installation of safety devices such as SVA & SVU Safety Valves from GEA.
Fully certified, they comply with the technical regulations of Internationally recognized classification authorities.
