Could somebody identify this dump valve, and what spring I should have in it please?

The car as it stands has; stage 1 remap, milltek exhaust, TIP, Uni intercooler, Jetex filter..

It currently has a green spring, is this right and is the dump valve recommended?
 
different spring rates for higher or lower boost so it doesnt leak etc etc
 
Think mine might be leaking. Bought the car over a year ago standard with just the forge 007, since then gone up to revo2 with ko3s and all the trimmings and still on standard spring :(
