Ebay Valve.. all good

I installed the 4WRPE bosch bargain valve found on ebay, along with my 4-20ma to +/-10V converter toady, in place of one of the 4WREE valves used on the tibia axis. The valve and electronics are both working well! I doubt we will use this valve in the final machine, however, with the use of my signal converter it has made a very cheap spare, the valve cost around £140 and excluding my design time the converter probably about £30. To purchase this valve from bosch, the list price would be £1600!
