I seriously doubt your spongy pedal is due to a problem with the proportioning valve. If you haven't replaced all the flex hoses recently, I would replace them with stainless braided hoses. They have become much more cost effective in recent years, and the increase in pedal feel is remarkable. If that doesn't solve the problem, then you have to start looking at the master cylinder and calipers.
