Kawasaki Hydraulic Valve

 

The KMX series consists of multiple control valves engineered to deliver systematic control over the actuators of excavators. Its integrated housing features a compact layout of complex main circuits and pilot signal circuits, optimizing structural design. To meet customized customer requirements, we offer bespoke, proprietary circuit configurations with a full range of special functions, such as straight travel, swing priority, high-pressure travel, flow merging and regeneration.

 

 

• Energy-efficient performance, enabled by low pressure drop and a flow regeneration function
• Precise operational control, supported by straight travel, priority control, flow merging and other practical functions
• Versatile functionality, compatible with auxiliary add-on valves for expanded application

• Semi-integrated valve body design, compact layout

• The KMX15 hydraulic valve adopts a semi-integrated structure, integrating the main oil circuit and pilot oil circuit within the valve body, significantly simplifying external pipelines and joints. This results in a compact overall layout, occupying less installation space, with a simpler pipeline arrangement and higher system integration, effectively improving equipment operational reliability. This is a core advantage of the KMX series compared to traditional split multi-way valves.

• Optimized flow path and low pressure loss design improve hydraulic system efficiency

  The internal oil passages have been optimized through fluid simulation, resulting in a more rational flow path and significantly reducing hydraulic oil flow pressure loss. Lower pressure loss allows the hydraulic pump output power to be transmitted to the actuators more efficiently, reducing energy waste, improving hydraulic system efficiency, and achieving fuel savings and reduced consumption.

• Outstanding performance in coordinated control of multiple actions

  Excavators often perform multiple actions simultaneously, such as boom lifting, stick extension and retraction, bucket retraction and extension, slewing, and traveling. This main control valve can precisely regulate multiple flow paths and rationally distribute the oil to each actuator, ensuring the synchronous and smooth operation of multiple actions.

• Supports regenerative oil circuit function to further reduce energy consumption. The valve body supports regenerative circuit configuration, which can recover the hydraulic oil released during the movement of the actuator and reuse it, reducing energy loss caused by overflow and continuously reducing the overall energy consumption of the machine.

 

 

• This hydraulic component is widely applied to various types of excavators for stable and efficient operation.
• It is perfectly suitable for crawler drills and pile drivers, delivering reliable performance in foundation construction projects.
• The product is also an ideal choice for forestry machinery, adapting to the tough working conditions of forestry operations. 

 

FAQ

 

Q1: What types of excavators is the KMX15 series hydraulic valve mainly used on?

A1: This series is primarily designed for medium-sized hydraulic excavators in the 20-30 ton class.

 

Q2: What control system does the KMX15 series use? Does it have pressure compensation functionality?

A2: The KMX15 series uses a negative flow control system. It detects pressure changes as the oil flows through the throttle orifice and sends a signal back to the main pump, thereby adjusting the pump's displacement and achieving energy savings.

 

Q3: What are the typical functions of the 15 series?

A3: This series of valves integrates multiple complex functions to meet the operational needs of excavators.

 

Q4: Will the internal confluence function cause flow exceeding limits?

A4: No. When performing combined actions such as boom lifting and stick digging, the oil from the dual pumps is supplied to one action through two independent valve cores before confluence. Not all flow passes through a single valve core, therefore, it will not cause single valve core flow exceeding limits.
