It been very hard to work out how the remote operated bilge valve works.
You can see the double handle in the picture in Reply #488. By lifting the handle, the control rod (WHITE) rises and opens the valve. The control rod (WHITE) is linked to a wheel (RED) and rotates a cross over rod (Yellow) to the other wheel (Red) which move the other handle.
Tore/Maciek, what do you think of this system?
