After some investigation it was noted the piston and oil intake were in our opinion manufactured in such away it was never designed to have control if the door was only opened a little way.
We therefore changed the configuration, designing a bespoke one way valve, manufacturing it and used it in conjunction with the original system. You can see the valve was incorporated into the head of a "manufactured" bolt in the picture, this was not the first design, we were going to place a new valve into the piston itself but this was decided against for a number of reasons.
The Wallace now has control from 1 degree, through and up to 90 degrees instantly.
