GEA AWP safety overflow valves SVU

Safety valves not dependent on back pressure, spring-loaded.

Safety Overflow Valves SVU

AWP safety valves are suitable for installation as relief valves in the refrigerant cycles of industrial refrigeration systems. Standard safety valves are safety devices for protecting the refrigeration system and their components from excess pressure (see also DIN 8975 part 7).

They comply with the technical regulations of the German Technical Control Board (TÜV). AWP- safety valves open up to the valve lift stop if the start-to-leak pressure (set pressure) rises within the 10% range. They close if the pressure drops to the 10% range below the set point. The valves open independently of back pressure.

Technical features:

  • Available in steel or stainless steel
  • Selection of body material as per German DIN EN12284, AD2000 Series W
  • Working media: glycol-based cold brine refrigerant EN 378 p. 1, e.g. NH3, R134a, R290 (propane), R507, blends with refrigerator oil, neutral, gas and liquid media, glycol-based cold brine
  • Mounting position: vertical as per AD2000-leaflet A2, and horizontal
