AWP dual safety overflow valves are designed for installation in the refrigerant cycles of industrial refrigeration systems. The safety valves which are independent of back pressure protect refrigeration systems and their components from excess pressure (see also EN 378 part 2). They comply with the technical regulations of the German Technical Control Board (TÜV) and with AD2000 regulations. Once the set response pressure is reached AWP safety valves begin to open. They open within a 10 % pressure increase until the designed limit of the lift is reached. When the pressure drops again they start closing once the set response pressure is reached. They close completely within a pressure drop of 10 % below the set reponse pressure.The 3-way valve enables easy checks and maintenances of the safety valves without the system’s operation to be interrupted. One of the two outlet nozzles is always open whereas the other one is closed. So one safety valve can be inspected or even disassembled while the other one is protecting the system.
