Valves used in safety applications tend to stay in opened or closed positions for very long, time intervals. As Emerson’s Joe McHugh explained in a Plant Engineering article, Double up on solenoid safety: …all valves experience stiction if they remain inactive for too long. (Note: Stiction is the friction that tends to prevent stationary surfaces […]

According to the Solenoid valve page on Wikipedia at the time this post was written, the invention of these devices dates back to 1910 by ASCO, now part of Emerson. Solenoid valves are electromechanical devices: …in which the solenoid uses an electric current to generate a magnetic field and thereby operate a mechanism which regulates […]

Wikipedia defines a solenoid valve as an: …electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can […]

For many applications in the process manufacturing and production industries, solenoid valves are used to “shut off, release, dose, distribute or mix fluids.” Wikipedia defines a solenoid valve as: …an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched […]

A post from a few years ago, Separate Versus Integral Final Element Accessories in Safety Applications, continues to generate some good questions. I thought I’d make these questions and associated answers more visible in today’s post. Here’s the first question: I understood the whole description, But while calculating PFDavg, We will have to add the […]
