Catalogue description records
This is a discharge valve assembly for the Kerr KZ-3150PT pump fluid end. It is a one-way fluid-end valve that opens on the pressure stroke to release pumped fluid and reseats to hold pressure on the return. The part is an aftermarket replacement for Kerr SKU KZ-300RD, listed for identification and fit reference rather than as an OEM-made item. It weighs about 0.53 lb.
A fluid-end valve assembly controls one-way flow through the pump — a suction valve admits fluid on the intake stroke and a discharge valve releases it on the pressure stroke. It typically comprises the valve body, seat, spring and guide.
