Different applications require different valve features
Breakthroughs in valve design have made major recent contributions to improving the efficiency levels in a PDH process. With the right valves, this efficiency is available now for the production of polymer-grade propylene without a steam cracker or fluid catalytic cracking unit.
What’s key for this particular application is to make sure that valves you choose offer efficient recovery, while guaranteeing safety under all circumstances.
If you’re uncertain about selecting the correct dryer switching valves for your unit, consider solutions capable of tolerating fluctuations in temperature while keeping bi-directional tightness over a period of several years of operation.
If choosing reactor depressurizing valves are a concern, search from solutions with extremely fast operation – a primary requirement for this function, as they must open instantly at over-pressurization. Also robust stem packing is a must to prevent any leaks that cause loss of product and safety issues.
