What valve to use to connect a Crosswater valve to copper pipes

[deanomc]

I am installing a three way shower (fixed head, bath and hand) and need to know what connectors to use to connect the five 22mm inlets and outlets to copper pipe. All pipework in the wall is 15mm copper pipes using york fittings. Is there and fitting out there that will connect direct to the shower ( male 22mm screw) which I will then be able to solder 15mm pipe direct to. Thanks

The only thing I can find is a 'Compression Adaptor 15mm x 3/4" Male' but I really would like to weld it and not use compression.
