Product Description
The KMX15RA Control Valve is a multi-way directional control valve (Directional Control Valve / Main Control Valve) used in excavator hydraulic systems. Its main function is to control the direction, pressure, and flow of hydraulic oil, thereby enabling the operation of various excavator working mechanisms such as the boom, arm, bucket, swing, and travel.
This control valve is commonly used in the hydraulic systems of small excavators. It features a compact structure, sensitive control, stable performance, and high reliability, making it one of the core control components of the excavator hydraulic system.
The KMX15RA directional control valve provides accurate control of hydraulic oil flow and direction, ensuring smooth and responsive operation of excavator functions such as boom, arm, bucket, swing, and travel.
The valve features a compact multi-section structure that allows efficient installation within limited space, making it ideal for small excavator hydraulic systems.
Manufactured with high-quality materials and precision machining, the KMX15RA control valve offers excellent durability and stable performance even under demanding working conditions.
The valve operates through a pilot control system, allowing operators to achieve precise and smooth control of hydraulic movements with minimal effort.
Designed to ensure consistent pressure and flow distribution, the valve contributes to efficient system performance and improved overall machine productivity.

Charge pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
1.What is the KMX15RA Directional Control Valve used for?
The KMX15RA Directional Control Valve is used in excavator hydraulic systems to control the direction, pressure, and flow of hydraulic oil. It distributes hydraulic power to different actuators such as the boom, arm, bucket, swing, and travel motors.
2.What type of valve is the KMX15RA?
The KMX15RA is a multi-section directional control valve designed for excavators. It consists of several valve sections, each responsible for controlling a specific hydraulic function.
3.Which machines commonly use the KMX15RA Control Valve?
The KMX15RA control valve is commonly used in small excavators, especially in machines within the 3–6 ton class.
4. What are the main features of the KMX15RA Control Valve?
The valve features a compact structure, high reliability, precise control, and stable hydraulic performance, making it suitable for demanding construction environments.
5. How does the KMX15RA Directional Control Valve work?
The valve operates by moving internal spools in response to pilot pressure or operator input. This movement directs hydraulic oil to specific circuits, allowing the excavator's working devices to perform their respective movements.
6. What are the main components of the KMX15RA Control Valve?
The main components include valve spools, valve body sections, relief valves, check valves, and pilot control mechanisms, which together regulate the hydraulic flow and pressure.
7. Why is the KMX15RA Control Valve important in an excavator?
It is one of the core components of the hydraulic system because it controls the distribution of hydraulic power to all working functions of the excavator.
8. What are the common signs of a faulty KMX15RA Control Valve?
Common symptoms include slow or irregular movement of the excavator functions, hydraulic leakage, unstable pressure, or difficulty controlling certain operations.
Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
