To remove the valve from the your Quest basin tap, firstly make sure you have turned off both water supplies. You can remove the handle by pulling it away from the valve and spline adaptor. You will need to unscrew the screw from the top of the valve and then remove the spline adaptor to avoid any damage. You should then be able to twist the valve out using a suitable spanner.
