Thank you to everyone that has commented so far.
I should point out that the valves to be rerated are 30" in size. The gate valve body is of the fabricate body design.
What would the steps be, or is it possible to perform an analysis of existing valves to qualify it to operate at a higher pressure?
I want to operate a 900# ANSI valve up to say 2500 psi. This valve is normally limited to 2160 psi case pressure. The valve is WxW in both through conduit and...
Thanks for the information. The formula worked. I plotted Stator temp - Ambient = Constant1 * Amps square plus Constant2. Then used Excel to do a bestfit trendline.
The results were fairly linear. Rsquared = .87 for one motor and .94 for the second.
I have a few stator winding temperatures recorded at a few different current readings and ambient temperatures. What is the formula/relationship of stator temperature as a function of ambient temperature and current? This happens to be a large 2500 hp 3ph 4160 induction motor.
I would like to...
