Yes. One quick way is to go to a motion/bearing supply and ask for a catalog. They may even be willing to help you select one. They may lean towards the higher priced versions, so use logic. Some of these vendors even have gas/liquid/hydraulic specialist in-house to help you. Also, one of the supply houses that carry a bundle of commercial gaggets (not mentioning a name)will have a choice to pick from. Many proportional or metering valves operate on small voltages. 12VDC should not be a problem. Often you purchase the valve and the correct coil or actuator for the voltage you are providing. If you want to select a various amount of flow according to how the engine is performing (for example), you will need a product in the cab that will vary the voltage to the valve in order to achieve this. This could be as simple as a wire wound resistor "pot" to divide the voltage and thus adjust the current flow to the coil making the valve adjustment. Be sure the "pot" will handle the current the coil or actuator is rated at. (And remember that leaning out an engine can cause it to get mighty hot at the top of the pistons. You can melt the piston domes.) -randy- The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
