Bathstore Quatra other components?

Hi, i have a Bathstore Quatra horizontal bath valve (with the 3 taps) CP0000250 is the correct replacement for the cartridge which I will be ordering however, there are 2 small valves with screw heads top and bottom of the main cartridge, I believe theses are to lower the pressure on either hot and cold inlets?? Are these available please and can you supply them? The one for the hot inlet (top one) the screw is solid and I have turned the brass screw head off.
