Thanks again. I assume by your first reply that finding a valve like this for just compressed air applications is hard as well, is this correct? Thanks.

Thanks for the response! Today I had a thought about using a rotary valve connected to an electric motor. I would just need a rotary valve that is open for 50% of the 360* turn. Is this idea feasible? I have pretty good CAD skills and could probably design something up real quick. The main...

I forgot to add, I am also having trouble finding keywords on what to search for.. Like I am at a complete loss at what type of airflow measurement I am looking for and can only think of CFM... If I do get a valve with a smaller orifice, can I just raise the pressure to get the same force?

Hello, I am trying to pulse pressurized steam in a fairly precise manner. I don't know much at all about valves, fluid dynamics, and such so any help would be greatly appreciated. My goal is to release pressurized steam at frequencies from 10Hz to 150Hz. The steam pressure used will not be...

Thanks, but my engine is apart right now so testing it like that is not possible.. The knock sensor is hard to change when the engine is assembled so I would like to test the knock sensor externally. I think I'll just buy a new knock sensor and find the differences...

Hi, I would like to test my knock sensor. I've read that they are piezoelectric devices and I happen to have a research project that deals with piezoelectric materials. I was wondering if I could use an impedance analyzer to determine whether or not my knock sensor is good or bad. If I do test...
