My goal is to release pressurized steam at frequencies from 10Hz to 150Hz. The steam pressure used will not be over 100psi for this testing(due to a safety release valve). I would like the valve to be connected to the system with 1/4" ID tubing. The issue I am having right now is I would like the pressure released to have the same force as my current setup. Right now, I am using a pipette nozzle with a 1mm opening and the pressure set to around 40-60psi. I also having trouble finding valves that meet the pressure, speed, or temperature requirements of steam.  Is there an equation I can use to find the amount of force x distance x pressure or do I have to find and plot it manually.Now, I have found a few high speeds solenoid valves but the orifices seem too small for application. I am also not sure if I could take a regular solenoid valve from McMaster-Carr and pulse it at these rates reliably..but for this unique application you should speak directly to someone with more focus on solenoid valves.  Parker-Skinner, ASCO, Clippard are names for small solenoid valves.  I will fearlessly prognosticate that you are above the frequency response offered by even those.  You may wind up looking at the type of valve used for an inkjet printer.  Not much volume, but good frequency response.  You also made it hard on yourself by wanting to flow steam.  Steam is hot enough to cause problems in the electronics of the type of valves you migh use.
