On each Moro Kaiser Boom, there are three solenoid assemblies. These solenoid assemblies are electric over hydraulic: when you push a certain direction on your pendant control the solenoid assembly sends hydraulic fluid to the correct hydraulic cylinder making the boom move in the desired direction.
The solenoid assembly consists of two coils (caps) and one manifold (block).
