can i fit a press equalising valve to a thermostatic shower?

[globalste]

Am considering ways to regulate the volume flowrate to the shower, as hot and cold are the same bore pipe, reducing pressure would reduce volume flowrate.

I thought about a pressure reduction valve to coldwater feed but not sure. The volume flowrate restrictor in the cold water restricts the shower too much and i get rubbish flow. Hmm, maybe i could drill the restrictor to increase bore?

have you considered telling us how the hot water is heated, and if hot and cold are the same pressure, or different?

Why do you need 2 do this ? As stated in last post has it been installed wrong ? ie Cold mains and gravity hot .
