Overflow valves not dependent on back pressure, spring loaded.
AWP overflow valves are suitable for use as relief valves in the refrigerant cycles of industrial refrigerating plants. Overflow valves are safety devices for protecting the refrigerating system or its components from excess pressure (see also DIN 8975 part 7). They open independently of back pressure and close if the pressure drops to the 10% range below the set pressure. They comply with the technical regulations of the German Technical Control Board (TÜV).AWP overflow valves are maintenance-free. Any defects that occur in the functional performance of the valves can be repaired.
