Catalogue description records
The EW446/C15 Lower Valve Guide is an aftermarket replacement part for the fluid-end valve assembly of EW446 and C15 mud pumps. It seats below the valve in the valve pot, keeping the valve aligned with its seat so the valve opens and closes squarely on each stroke. Model and part references are used only to identify fitment; the guide is an aftermarket component and is not represented as OEM-manufactured.
The lower valve guide supports and centres the valve body from beneath, keeping it aligned to its seat through each stroke.
