Product Overview
The CAT 345-9961-01 is a solenoid-actuated directional control valve engineered for precise hydraulic circuit switching in Caterpillar heavy equipment and compatible industrial hydraulic systems. Operating on a two-position, four-way spool configuration, this valve directs pressurized fluid to extend or retract actuators, cylinders, and motors through electrical solenoid command. As a standard directional control valve, it serves as a critical control element in load-sensing and open-center hydraulic circuits, providing reliable flow routing with minimal internal leakage and fast response characteristics. The 345-9961-01 is manufactured to Caterpillar OEM tolerances, ensuring direct interchangeability and long service life in demanding mobile and stationary hydraulic applications.
