At around 500PSI it doesn't take much area to get a significant force and yes it is around 5%...

    Custom valve design and seating pressure

    Thanks for the input. I will try my best to answer the questions. "Also, calculate the force margin of the two valves, i.e. what is the closing force acting per linear inch of seal length per unit of inlet-outlet pressure differential. LI, if you look, the seal line (line of contact btwn seal...

    Valve Seal design - Issues with holding pressure

    Hi Guys, I am working with a prototype in which we designed a valve seating against an Oring. Please see below To seat the valve there is a spring force and a pressure force as indicated by the arrows. The valve works well for our pressure range 0-600 Psi. The problem is when a colleague...
