Catalogue description records
This is a suction valve assembly for abrasive service, built for the Kerr KA-3500PT and Q5450PT pumps. Fitted in the fluid end, the suction valve opens on the intake stroke and closes against its seat on the pressure stroke to control one-way flow; the abrasive-service configuration is intended for duty handling abrasive media. It fits the KA-3500PT, T50 and T50-PT pump models and is an aftermarket replacement for Kerr SKU KA-305HT.
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.
