KMX15RQ Hydraulic Control Valve
Kawasaki KMX15RQ is a pilot-operated multi-way valve from the KMX15 series, designed for 20–25 t excavators. With a rated flow of 300 L/min and maximum pressure of 34.3 MPa, it features a precision-cast, integrated valve body and incorporates functions such as linear travel, swing-priority, and regenerative merging. Known for low energy consumption, high-precision control, and reliability, it serves as the core control component in medium-sized excavator hydraulic systems.
Key Features
1.Integrated Precision Valve Body
Fully cast, one-piece construction with CFD-optimized internal flow channels reduces pressure loss by 15–20% compared with sectional valves, minimizes leakage and deformation risks, and ensures a compact, easy-to-install and maintain design.
2.Energy-Saving Regenerative Circuit
Built-in regeneration for boom, arm, and bucket circuits converts potential energy into hydraulic energy, reducing system heat, increasing lowering speed, and preventing overspeed, delivering significant energy savings.
3.Precise Multi-Function Control
Supports linear travel, swing-priority, travel boost, and dual-pump merging. Multi-function responses are fast, smooth, and coordinated, enhancing operator feel and work efficiency.
4.Dual-Level Safety System
Main safety valve combined with branch safety valves protects the system. Main valve set at 31.4 MPa (standard) / 34.3 MPa (high), branch valves protect individual actuators from overload, improving overall system safety.
5.Low Noise and Smooth Operation
Optimized valve stem shoulder angles and flow transitions reduce directional shock and hydraulic noise, providing quieter, more comfortable operation.
6.Flexible Expansion Options
Additional auxiliary sections can be added to support attachments such as breakers and hydraulic shears, enabling customized solutions.
