A diverter valve is basically the exact opposite of a wastegaste. A wastegate is used to relieve drive pressure, while a diverter valve helps drive the turbo harder. Basically a flange with a flapper that closes off one volute on the exhaust side of your turbo. It redirects the exhaust gas to one part of the turbine wheel, driving it harder and helping it spool up. When you start off the flapper is closing off the one volute. Once you reach whatever boost level you have it set at, for example 5 psi, the flapper opens back up and gives exhaust to the whole turbine wheel like normal.
