The multi-way valve allows the operator to precisely control the various hydraulic functions of the excavator, realize the combined control of multiple hydraulic channels, make the operation more flexible, thereby improving work efficiency and reducing operation time. The multi-way valve can improve the versatility of the equipment, reduce hydraulic loss and meet different work needs by distributing hydraulic oil to different actuators (such as bulldozing, digging, grabbing, etc.).

The selling point of Rexroth hydraulic pumps is their high performance, precise control, environmental protection and energy saving, and global service network. They are suitable for high-end excavators and users who need complex operations, and customers who focus on high efficiency and long-term economic benefits. Doosan hydraulic pumps are more suitable for customers who need strong reliability and cost control due to their strong power, stable output, high cost performance and adaptability to harsh environments, especially in medium-sized excavators and high-load operations. Both have their own characteristics and can meet the needs of different markets and customers.

The R90 excavator has become a core competitive product in export trade with its efficient and energy-saving engine, advanced electronically controlled hydraulic system, enhanced structural design, comfortable driving environment, convenient maintenance system, excellent performance parameters and brand strength.
