in effect the motor has not got a well done cnc machining like you guess.
I have only done some micro adjustment to some components and the torque is raised slightly but is still not enough.
I have to improve it further!
I never give up!
Here is my new open center hydraulic valve, built to search the best in terms of smoothness, low actuation force, compactness and durability.
This time, for a longer lifespan, i built it with alloy steel hardened, a small production series for my and some friends.
The system is modular hence i can put together from 1 to 10 or more valves in an in-line assembly.
The video below shows three of them and only one with servo Hitec Hs82 installed.
This valves are already at work on a Cat 365 of a friend. The model weights 40 Kg and work at 45 BAR of pressure without any problem, so i'm quite happy.
