If the valve is bent, it will not seal the exhaust properly (it will leak out of the barrel). It could do this irregularly during a shooting session or may get stuck in the open position and not seal at all. It might affect accuracy if the valve doesn't open or close consistently, resulting in large variations of velocity. I've not seen this; typical symptom is the exhaust valve leaks. If you are mechanically inclined this is something that can be replaced if you order the valve body assy with the exhaust valve from RAW.
