Pilot-operated valve KMX series

flow-controlactuator controlmodular

Overview
The KMX series are multiple control valves designed to coordinate hydraulic actuators on excavators. Main and pilot circuits are compactly integrated into a single housing. Customized circuits and special functions — such as straight travel, swing-priority, high-pressure travel, flow confluence and regeneration — can be configured to meet machine requirements.

Features

• Energy-efficient design with low pressure drop and flow regeneration capability
• Precise controllability including straight travel control, priority circuits and flow confluence
• Modular functionality with auxiliary add-on valve options for machine-specific functions

Specifications

• Models: KMX13, KMX15, KMX32, KMX36
• Max. pressure: 34.3 MPa
• Rated flow: KMX13 = 180 L/min; KMX15 = 300 L/min; KMX32 = 450 L/min; KMX36 = 550 L/min
• Special circuits/functions: straight traveling, swing priority, highly pressurized traveling, confluence, regeneration

Applications

• Hydraulic excavators
• Crawler drills and pile drivers
• Forestry machinery

Focus
CFD (Computational Fluid Dynamics)-led design optimizes internal oil passages to minimize pressure loss and improve overall hydraulic efficiency.

Excavator system
Common excavator hydraulics use a variable displacement pump in an open-center control layout. Electronically controlled fixed-displacement systems are also used to optimize individual functions for smooth, efficient and precise machine control.
