New exida Article in Valve Magazine

A new article written by exida safety engineer Loren Stewart appears in Valve Magazine. The article is entitled How to Improve Reliability and Safety of Solenoid Valves.
In an industrial setting such as a chemical plant, oil refinery or a deep-sea oil rig, there are safety instrumented systems in place that are designed to promptly bring about a safe shutdown of a process if certain hazardous conditions are detected. Such safe shutdowns frequently involve isolating a process fluid flow, often accomplished using an ESD (emergency shutdown) valve. If the ESD fails dangerously, when a hazardous condition necessitating a shutdown occurs and the ESD does not perform its function when required, the worst-case consequences can be catastrophic.
