Catalogue description records
This 3PN700 Valve Assembly is an aftermarket replacement part for the 3PN700 mud pump. 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 — and typically comprises the valve body, seat, spring and guide. It is supplied to match the form and fit of the 3PN700; the model designation is used for identification only and does not imply original-manufacturer production.
