Paul, <br>
Best bet is to get some reference books from the libary or from a leading hydraulic manufactor. Parker Hannifin Corp.,<br>
has a number of hand books available, (parker.com.).<br>
I have bulletin # 0222-b2, Analyzing Hydraulic Systems.<br>
I'm not sure if mine is still available...
Paul,<br>
I beleive will will need more info. ( hydraulic/ air )<br>
Flow rate (GPM/LPM), fluid viscosity and<br>
specific gravity <br>
<br>
Example:<br>
Assume 50 GPM is flowing through 1 1/4" schedule 80 pipe. Viscosity is 100SUS and specific gravity is .865.<br>
pressure drop through 90 deg...

I can't understand why you would want a valve to follow the pressure you already have. You will have to explain it to me. The Hussco valve is a proportional pressure reducing valve used to operate larger prop. valves and pumps. The set pressures are comon for all manufactors.<br>...
Craig,<br>
Pressure drop or delta P, depends on the fluid flow ( in GPM ) ,Friction factor, Density and lenth. If you look at any <br>
good fluid power hand book the formula should be their.<br>
I have it, but can't type it accurately.<br>
Ofcorse, you can always put a gauge or transducer on...

All manufactors publish the cracking pressure for their style of valve. Velocity is not the a factor, although you do need flow to create pressure. <br>
Because all valves are made different, you should contact the manufactor to answer your question.
