Our fitment list for the K7V125 covers open-circuit construction machinery or industrial equipment. Fitment is a starting point: send the nameplate photo of the unit on your machine and we confirm the control suffix (DT / DTP / DTH) before you order.
FRANK primarily supplies FLUTEK products and also offers other brands. Contact us to confirm the exact brand and configuration before ordering. Machine brand names describe applications and do not by themselves confirm fitment.
