Valves are used for controlling the air, oil and refrigerant circuits in compressors. They function mechanically and open and/or close at defined pressures. In case a valve functions incorrectly or does not function at all, this can lead to contamination of the connected system and end product, overheating as well as an unforeseen failure of the compressor.
Valves thus fall within the scope of those wear parts that are replaced during proactive maintenance before they can possibly fail.
The STASSKOL valves go under the name ESKAmaxflow. They complete the wide product range of wear parts that the company offers for piston compressors.
The design of the ESKAmaxflow valve series has been developed on the basis of the finite element method, abbreviated as FEM.
Tests of various valve designs revealed that valve seats with conical holes are significantly better in terms of flow behaviour, stress and deformation as compared to seats with oblong holes.
The gas flow has been calculated and optimised with CFD. This was followed by extensive tests of the valves in the in-house technical centre as well as numerous test runs in the field.
