Diesel Stop Solenoids: Finding the Right Fit

[Josh111]

I am designing a stop system for a old diesel engine. The application I am using needs a pull type solenoid that can have a stroke of 9/16" - 1 1/2". it needs to have a return spring of at least 20 lbs. It needs to be continuous duty ( probably 2 coil).This will be used as a "engage to run" setup. The spring loaded solenoid will push the injector shut when power is removed.



I have looked at several brands including F. W. Murphy and Trombetta. These do not seem to meet my requirements. I did however find some in the woodward/synchrostart line that will work, however they are quite expensive. Can anyone tell me what some other companies are that make diesel stop solenoids?

These are the models I have looked at:

F. W. Murphy #RP2309B

Trombetta 600 Series
Woodward # 2370 - 12 -E2U1B5S2
