Catalogue description records
This is an abrasive-resistant (AR) suction valve assembly for the SC-170DD pump. A fluid-end suction valve assembly admits fluid on the intake stroke and typically comprises the valve body, seat, spring and guide. The "AR" designation indicates it is configured for abrasive service. It is supplied as an aftermarket replacement part matched to the SC-170DD fluid end.
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.
