Garland Maine | My knowledge here comes from raven controls of Pwm valves on rogator sprayers and such.
Another possibility: in the vicinity of the electric coil on the hydraulic valve, is there an acorn nut? Possibly looks like it holds the coil on to the valve.
This acorn nut should be on the stem of the valve. The valve will spring closed, and the coil will pull the valve open a variable amount based on the pulses from the controller.
The acorn nut can be tightened to pull open the valve manually. So in the event of a controller failure you can tighten the nut and operate the flow manually.
Might work for you, might not. | |
