Many heavy construction machines, such as excavators, motor graders, and bulldozers, have hydraulic pumps as part of their hydraulic systems. These pumps are designed to pump high-pressure hydraulic oil (oil) and are controlled by the hydraulic motor control unit, which determines how much oil is pumped through the system. The CAT374D control valve is a two-position, two-way, four-way globe valve with a self-operated overflow function and high-performance hydraulic positioning. This valve is intended for use in excavator hydraulic systems. The product also aids in lowering system power consumption and increasing system efficiency.
