Titan 235-021A Valve Rod Assembly for Hydraulic Motor Service
Titan 235-021A is an OEM valve rod assembly used in the hydraulic motor of compatible PowrTwin, PowrLiner, PowrTex, and ProMark sprayer models. This assembly supersedes the older 235-021 designation and is listed in official Titan service manuals for PowrTwin 5500 and PowrTwin 6900 DI Plus. The valve rod assembly controls hydraulic flow within the motor and provides the spring-loaded valve action required for proper pump cycling. During hydraulic motor reassembly, Titan service instructions specify inspecting the valve rod assembly for damage and verifying normal spring action before installation. A broken spring retainer, worn valve rod, or damaged assembly causes valve sticking, erratic pump operation, or complete motor failure. This replacement restores reliable flow control and safe hydraulic motor function.
