The core tube is the metal tube in the centre of the coil. Remove the plastic screw on the end, slide off the coil and there is the core tube. They usually screw into the main valve body or are clamped on with bolts.
You could use a rotary flow divider for accurate flow splits. I have never seen one for water, only oil but I can't see why they wouldn't make them for water.
Some sort of reduction gearing would make this a fairly simple job. You could then use a small electric motor which would probably be easier and cheaper than a hydraulic system.
What type of motor is that? It has a very low pressure rating and very high flow. A pump that produces that sort of flow will be quite a lot larger than what you actually require if you go up in pressure and down in flow.
(you can't escape me)
I want to learn as much as I can about marine propellors. I want to start with the maths side first and although all the basics are covered in general maths educational materials, I am looking for something more biased towards marine propulsion. Does anyone know a website with lots of diagrams...
A lot of dislike for a master/slave set up in here. Sure a servo operated system would be nice and more accurate but as the OP has pointed out several times, accuracy is not the most important thing in this application.
Master slave will work, just fit some PRV's and bleed points in a couple...
As there is no flow at the dead end, there is no pressure drop. If there was flow, there would be a pressure drop but then by definition, it would not be a dead end. Remember flow is just an arbitrary representation of the rate in which force can be created in hydraulics.
