I would like to ask for help in solving the problem with the stuck VHP valve. There was a problem with reproducibility, from the tube from port 4 leaked very very slowly, one drop every few minutes. I cleaned the rotor and stator, screwed the valve head on - evenly, slowly to the first resistance until the head rested on the valve base. When I started it for the first time, I heard "wrrrr" and an error popped up. I unscrewed the screws 1/2 turn, the valve works, but the leak remains. The stator surface is perfect and the rotor doesn't look bad either. I attach photos.
1. Maybe the valve axis has too much resistance or the motor has lost torque? I would like some suggestions, simple rotor replacement due to its price (ca $ 500 !!) is a last solution, ,?
2. Is it possible to disassemble and remove the entire VHP valve block from the outside after unscrewing 3 screws (red dot)?
