Catalogue description records
The SJ300 Valve Assembly is an aftermarket replacement part for SJ300 mud pumps. A fluid-end valve assembly controls one-way flow through the pump — admitting fluid on the suction stroke and releasing it on the discharge stroke — and typically comprises the valve body, seat, spring and guide. It is supplied to match the form and fit of the original SJ300 component; the model designation is used for identification only and does not imply original-equipment manufacture.
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.
