This is a genuine OEM sourced replacement valve kit designed for DeWALT air compressors. The purpose of the valve plate is to allow air into the cylinder. Once the piston starts traveling up the reeds on the valve plate open and the air is sent into the tank. Over time valves and gaskets will become worn and would need to be replaced to keep your equipment running well. To complete this repair you would need a wrench set and a screwdriver to take off the housing and the cylinder head. Keep in mind this high-quality valve plate assembly is made of durable metal and is sold as an individual component.
