LESER Pressure Relief Valves for the Technical Gas Industry

The processes for the production of gases in the air separators to transport, store and process technical gases must be efficient and safe.
Your critical system components must function safe and reliably, and have simple maintenance measures that you are prepared for. Particularly true for the low-temperature and oxygen applications that have strict requirements for the selection of materials, and free from oil and grease.
Plants for technical gases contain many pressure relief valves of different sizes. These range from small valves for thermal expansion, to XXL valves for the initially high volume flows. For these in particular the tightness of your valves are crucial for best efficiency.
