The challenge
The ARKEMA company operates its plant in non-stop mode, which requires high availability of the connected supply equipment, such as tanks with compressed air. To ensure high availability of the plant, ARKEMA opted for the new change-over valves from LESER .
Why did the customer choose LESER products ?
For ARKEMA, quality and reliability are the most important decision criteria when choosing Safetys and Change-over valves .
More efficient plant operation with LESER change-over valves
The LESER change-over valve of the type n 330 and 320 offers the solution for safe and efficient plant availability 24 / 7. It is easy to operate and, in combination with Safetys valves , provides permanent protection for a permanently running plant.
Flow tests and computational fluid dynamics (CFD) simulations were used to develop a flow-optimized design with minimal pressure loss.
Each configuration of these change-over valves has a specific resistance coefficient that allows reliable and precise calculation of the inlet pressure drop .
Due to their durable design, these new change-over valves are maintenance-free and tested through endurance trials. They are the economical solution because a suitable selection can be made for every application .
